    Infineon Technologies Released New OptiMOS™ 5 Linear FET 2

    2 Min Read

    The safe hot-swap operation in AI servers and telecom requires MOSFETs with a robust linear operating mode as well as a low R DS(on). Infineon Technologies AG addresses this challenge with the new OptiMOS™ 5 Linear FET 2, a MOSFET designed to provide the ideal trade-off between the R DS(on) of a trench MOSFET and the wide safe operating area (SOA) of a classic planar MOSFET.

    The device prevents damage to the load by limiting the high inrush current and ensures minimal losses during operation due to its low R DS(on). Compared to the previous generation (the OptiMOS Linear FET), the OptiMOS Linear FET 2 offers improved SOA at elevated temperatures and reduced gate leakage current, as well as a wider range of packages. This allows for more MOSFETs to be connected in parallel per controller, reducing bill-of-material (BOM) costs and offering more design flexibility due to the extended product portfolio.

    The 100 V OptiMOS 5 Linear FET 2 is available in a TO-leadless package (TOLL) and offers a 12 times higher SOA at 54 V at 10 ms and 3.5 times higher SOA at 100 µs compared to a standard OptiMOS 5 with similar R DS(on). The latter improvement is particularly important for the battery protection performed inside the battery management system (BMS) in case of a short circuit event. During such events the current distribution between parallel MOSFETs is critical for the system design and reliability.

    The OptiMOS 5 Linear FET 2 features an optimized transfer characteristic that allows for improved current sharing. Taking into account the wide SOA and improved current sharing, the number of components can be reduced by up to 60 percent in designs where the number of components is determined by the short-circuit current requirement. This enables high power density, efficiency, and reliability for battery protection which are used in a wide range of applications including power tools, e-bikes, e-scooters, forklifts, battery back-up units and battery-powered vehicles.

    The new OptiMOS 5 Linear FET 2 MOSFET is now available. Further information can be found at www.infineon.com/optimos-linearfet and www.infineon.com/ipt023n10nm5lf2.

  • Toshiba to Sample 1200V SiC MOSFETs in Bare Die Format

    Toshiba to Sample 1200V SiC MOSFETs in Bare Die Format

    3 Min Read

    Toshiba Electronics Europe GmbH has developed new 1200V silicon carbide (SiC) MOSFETs with low on-resistance (RDS(ON)) and high levels of reliability. The devices are particularly suited to applications within automotive traction inverters. They are now available and shipping as early test samples in bare die format – allowing customers to customise them to meet the needs of their applications.

    The new X5M007E120 uses a manufacturing process that reduces on-resistance per unit area by up to 30%. Unlike existing methods that utilise a striped-pattern construction, the new devices arrange the embedded Schottky barrier diodes (SBDs) in a check-pattern to achieve lower on-resistance.

    Many SiC MOSFETs increase on-resistance as body diodes are energised during reverse conduction, which can lead to reliability issues. Toshiba SiC MOSFETs alleviate this issue by preventing body diodes from operating as SBDs are embedded into the MOSFETs. This approach maintains the reduction in on-resistance while ensuring reliability during reverse conduction.

    With electric motors consuming over 40% of the world’s electrical energy, efficient operation is essential to sustainability. The re-arrangement of SBDs in this device has suppressed body diode energisation, and the upper limit of unipolar operation has increased to around double without increasing the SBD mounting area. Additionally, channel density is improved. These enhancements contribute to energy efficiency in applications, including motor control inverters.

    Reducing RDS(ON) within a SiC MOSFET can cause excess current flow during short-circuit operations. By adopting a deep barrier structure, the X5M007E120 reduces excessive current within the MOSFET section and leakage current in the SBDs section during short-circuit operation. This enables durability during short-circuit conditions while maintaining high levels of reliability against reverse conduction operation.

    The new X5M007E120 has a VDSS of 1200V and is rated for a drain current (ID) of 229A continuously, with 458A for pulsed operation (ID Pulse). RDS(ON) is as low as 7.2mΩ, and the device can operate with channel temperatures (Tch) as high as 175°C. The devices are AEC-Q100 qualified for automotive applications.

    Engineering samples of the new X5M007E120 are expected to ship during 2025, with mass production samples scheduled to start in 2026.

    Toshiba will continue to seek ways to further improve the characteristics of its products. The company will contribute to realising a decarbonised society by providing customers with power semiconductors for applications where energy efficiency is essential, such as inverters for motor control and power control systems for electrical vehicles.

    Nexperia Introduced New Series of High-Performance Gate Driver ICs

    2 Min Read

    Nexperia introduced a new series of high-performance gate driver ICs designed for driving both high-side and low-side N-channel MOSFETs in a synchronous buck or half-bridge configuration. These devices deliver high current output and excellent dynamic performance, boosting efficiency and robustness in applications.

    The automotive-qualified NGD4300-Q100 is ideal for electronic power steering and power converters, while the NGD4300 has been designed for use with DC-DC converters in consumer devices, servers and telecommunications equipment as well as for micro-inverters used in various industrial applications.

    The floating high-side driver in these ICs can operate from bus voltages up to 120 V and use a bootstrap supply with an integrated diode, features which simplify overall system design and help to reduce PCB size. They can deliver up to 4 A (peak) source and 5 A of sink current to guarantee short rise and fall times even for heavy loads.

    The gate driver has a low 13 ns delay and offers excellent channel-to-channel delay matching of only 1 ns. These delays are significantly lower than for similar competing gate drivers and help to minimize dead-time by maximizing switching duty-cycle. 4 ns rise and 3.5 ns (typical) fall times help to deliver higher efficiency and support high frequency and fast system control. These gate drivers accept input control signals complying with both TTL and CMOS logic levels.

    “These devices are the first in our new portfolio of high-performance half-bridge gate drivers” according to Irene Deng, general manager of the IC solutions business group at Nexperia. “This release demonstrates how Nexperia is using process innovation to respond to the burgeoning demand for robust gate drivers that can increase power converter efficiency while also delivering smoother motor control in consumer, industrial and automotive applications.”

    For superior robustness in power conversion and motor driving applications, these ICs are fabricated using a silicon-on-insulator (SOI) process. This allows the negative voltage tolerance of the HS pin to extend to -5 V, significantly reducing the risk of damage caused by system parasitic component and unexpected spikes. The NGD4300 and NGD4300-Q100 are available in a choice of DFN-8, SO-8 and HSO-8 packages to offer engineers the flexibility to trade-off between device size and thermal performance, depending on application requirements.

  • ROHM Developed Surface Mount SiC Schottky Barrier Diodes that Improve Insulation Resistance by Increasing Creepage Distance between Terminals

    2 Min Read

    ROHM has developed surface mount SiC Schottky barrier diodes (SBDs) that improve insulation resistance by increasing the creepage distance between terminals. The initial lineup includes eight models – SCS2xxxNHR – for automotive applications such as onboard chargers (OBCs), with plans to deploy eight models – SCS2xxxN – for industrial equipment such as FA devices and PV inverters in December 2024.

    The rapidly expanding xEV market is driving the demand for power semiconductors, among them SiC SBDs, that provide low heat generation along with high-speed switching and high-voltage capabilities in applications such as onboard chargers. Additionally, manufacturers increasingly rely on compact surface mount devices (SMDs) compatible with automated assembly equipment to boost manufacturing efficiency. Compact SMDs tend to typically feature smaller creepage distances, fact that makes high-voltage tracking prevention a critical design challenge.

    As leading SiC supplier, ROHM has been working to develop high-performance SiC SBDs that offer breakdown voltages suitable for high-voltage applications with ease of mounting. Adopting an optimized package shape, it achieves a minimum creepage distance of 5.1mm, improving insulation performance when contrasted with standard products.

    The new products utilize an original design that removes the center pin previously located at the bottom of the package, extending the creepage distance to a minimum of 5.1mm, approx. 1.3 times greater than standard products. This minimizes the possibility of tracking (creepage discharge) between terminals, eliminating the need for insulation treatment through resin potting when surface mounting the device on circuit boards in high voltage applications. Additionally, the devices can be mounted on the same land pattern as standard and conventional TO-263 package products, allowing an easy replacement on existing circuit boards.

    Two voltage ratings are offered, 650V and 1200V, supporting 400V systems commonly used in xEVs as well as higher voltage systems expected to gain wider adoption in the future. The automotive-grade SCS2xxxNHR are AEC-Q101 qualified, ensuring they meet the high reliability standards this application sector demands.

    Going forward, ROHM will continue to develop high-voltage SBDs using SiC, contributing to low energy consumption and high efficiency requirements in automotive and industrial equipment by providing optimal power devices that meet market needs.
