Alpha and Omega Semiconductor Limited announced the release of two αMOS5™ 600V FRD Super Junction MOSFETs. αMOS5™ is AOS’s market and application-proven high voltage MOSFET platform, designed to meet the high efficiency and high-density needs of servers, workstations, telecom rectifiers, solar Inverters, EV charging, motor drives and industrial power applications.
The design of today’s mid-high power switched-mode power supply (SMPS) and solar inverter systems boil down to four major challenges – higher efficiency, higher density, lower system costs, and uncompromised robustness. High Voltage Super Junction MOSFETs are dominant the choice for topologies such as single/interleaved/dual boost/CrCM TP PFCs, LLC, PSFB, multi-level NPC/ANPC and so forth.
αMOS5™ has been the leading High Voltage Super Junction solution tailored for fast switching, ease-of use and robustness in mission-critical applications. αMOS5™ FRD FETs are engineered with strong intrinsic body diode to handle hard commutation scenarios, when the freewheeling body diode is in reverse recovery due to abnormal operations, such as short-circuit or start-up transients.
The two products released, the AOK095A60FD (TO-247) and AOTF125A60FDL (TO-220F), are 600V FRD FETs with 95mohm and 125mohm maximum Rdson, respectively. In tests conducted by AOS engineers, the body diodes of these two FRD FETs have survived high di/dt, under abnormal system conditions, even at elevated junction temperatures of up to 150°C. Additionally, AOS tests have shown that these devices’ turn off energy (Eoff) are noticeably lower than the competition’s, which contributes to higher efficiency in light or mid-load conditions.
“We defined our products for traditional power supplies, as well as DC/DC and DC/AC converters of solar inverters and ESS systems, where bi-directional topologies are needed. As energy storage-ready inverters become the trend and high voltage batteries are utilized increasingly in AC-coupled systems, the AOK095A60FD and AOTF125A60FDL will become industry leading solutions for bi-directional DC/DC and inverter/PFC applications that serve a wide range of power supplies, solar PV inverters, and ESS hybrid converters,” said Richard Zhang, Senior Director of Product Line and Global Power Supply Business at AOS.
Technical Highlights
- Rugged, fast recovery diode (FRD) with reduced Qrr for demanding use cases
- Engineered for both hard and soft switching topologies with ultra-low switching loss
- Strong UIS and SOA capabilities
- Engineered to prevent self turn-on
- Suitable for LLC, PSFB, CrCM Totem-Pole, Multi-level NPC and CrCM H-4/Cyclo Inverter applications

The paradigm shift towards offloading complexity to suppliers and adopting smaller IGBT modules is evident in various applications. In response to the global push for downsizing and integration, Infineon Technologies AG introduced the 4.5 kV XHP™ 3 IGBT modules that will fundamentally change the landscape for medium voltage drives (MVD) and transportation applications operating at 2000 to 3300 V AC in 2- and 3-level topologies.
Applications benefiting from the new devices include large conveyor belts, pumps, high-speed trains, locomotives, as well as commercial, construction and agricultural vehicles (CAV).
The XHP family comprises a 450 A dual IGBT module with TRENCHSTOP™ IGBT4 and an emitter-controlled diode, and a 450 A double diode module with emitter-controlled E4 Diode. Both modules feature improved isolation of 10.4 kV. Together, they help to simplify paralleling and downsizing without sacrificing efficiency.
Previously, complex busbars were required to parallelize switching modules, resulting in complicated design efforts and leakage inductance. The innovative design of the XHP family simplifies paralleling by conveniently placing the connections side by side. As a result, only a single straight busbar is required for paralleling.
The 4.5 kV XHP family also allows developers to reduce the number of units. Conventional IGBT solutions use multiple single switches and a double diode. With the new devices, however, designs can be reduced to two dual switches and a smaller double diode – a significant step forward in integrated drives.
The combination of the XHP 3 FF450R45T3E4_B5 dual switch and the DD450S45T3E4_B5 double diode enables significant cost savings and a smaller footprint. For example, Infineon’s previous IGBT solutions required four 140 x 190 mm² or 140 x 130 mm² switches and one 140 x 130 mm² double diode. With the new XHP family, the components can be reduced to two 140 x 100 mm² dual switches and a smaller 140 x 100 mm² double diode.
The IGBT modules FF450R45T3E4_B5 and DD450S45T3E4_B5 are available now. More information is available at www.infineon.com/XHP.

The accelerated transition to electric vehicles has led to significant innovations in charging systems that demand more cost-efficient and high performing power electronics. Addressing this, Infineon Technologies AG expands its 650 V CoolMOS™ CFD7A portfolio by introducing the QDPAK package.
This package family is designed to provide equivalent thermal capabilities with improved electrical performance over the well-known TO247 THD devices, thus enabling efficient energy utilization in onboard chargers and DC-DC converters.
Efficient and powerful electric vehicle charging systems help reduce charging times and vehicle weight, increasing design flexibility and reduce the total cost of ownership of the vehicle. This new addition complements the existing CoolMOS CFD7A series, offering versatility with top-side and bottom-side cooled packages. The QDPAK TSC (top side cooled), enables designers to achieve higher power densities and optimal PCB space utilization.
The 650 V CoolMOS CFD7A offers several important features for reliable operation in high-voltage applications. Thanks to its reduced parasitic source inductance, the device can minimize electromagnetic interference (EMI), ensuring clear signals and consistent performance.
The Kelvin source pin also provides improved precision for current sensing, ensuring accurate measurements even in challenging conditions. With a creepage distance suitable for high voltage applications, as well as high current capability and high power dissipation (P tot) of up to 694 W at 25°C, it is a versatile and powerful device for a wide range of high-voltage applications.
New system designs using 650 V CoolMOS CFD7A in QDPAK TSC will maximize PCB space use, doubling power density and enhancing thermal management via substrate thermal decoupling. This approach simplifies assembly, eliminates board stacking and reduces the need for connectors, thereby lowering system costs. The power switch reduces thermal resistance by up to 35 percent, providing high power dissipation that outperforms standard cooling solutions.
This feature overcomes the thermal limitations of bottom side cooled SMD designs using FR4 PCBs, resulting in a significant boost in system performance. The optimized power loop design locates drivers near the power switch, improving reliability by reducing stray inductance and chip temperatures. Overall, these features contribute to a cost-effective, robust, and efficient system ideal for modern power needs.
As announced in February 2023, the QDPAK TSC package has been registered as a JEDEC standard for high-power applications, helping to establish a broad adoption of TSC in new designs with one standard package design and footprint. To further to accelerate this transition, Infineon will also release additional Automotive Qualified devices in QDPAK TSC for onboard chargers and DC-DC converters in 2024, such as 750 V and 1200 V CoolSiC™ devices.
