Toshiba Electronic Devices & Storage Corporation has added DTMOSVI(HSD), power MOSFETs with high-speed diodes suitable for switching power supplies, including data centers and photovoltaic power conditioners, to its latest-generation DTMOSVI series with a super junction structure. Shipments of the first two products “TK042N65Z5” and “TK095N65Z5,” 650V N-channel power MOSFETs in TO-247 packages, start today.
The new products use high-speed diodes to improve the reverse recovery characteristics important for bridge circuit and inverter circuit applications. Against the standard DTMOSVI, they achieve a 65% reduction in reverse recovery time (trr), and an 88% reduction in reverse recovery charge (Qrr) (measurement conditions: -dIDR/dt= 100A/μs).
The DTMOSVI(HSD) process used in the new products improves on the reverse recovery characteristics of Toshiba’s DTMOSIV series with high-speed diodes (DTMOSIV(HSD)), and has a lower drain cut-off current at high temperatures. The figure of merit “drain-source On-resistance × gate-drain charges” is also lower. The high temperature drain cut-off current of TK042N65Z5 is approximately 90% lower, and the drain-source On-resistance × gate-drain charge 72% lower, than in Toshiba’s current TK62N60W5.
This advance will cut equipment power loss and help to improve efficiency. The TK042N65Z5 shows a maximum improvement in power supply efficiency over the current TK62N60W5 of about 0.4%, as measured in a 1.5kW LLC circuit.
A reference design, “1.6 kW Server Power Supply (Upgraded)”, that uses TK095N65Z5 is available on Toshiba’s website today. The company also offers tools that support circuit design for switching power supplies. Alongside the G0 SPICE model, which verifies circuit function in a short time, highly accurate G2 SPICE models that accurately reproduce transient characteristics are now available.
Toshiba plans to expand the DTMOSVI(HSD) line-up with the release of devices in TO-220 and TO-220SIS through-hole packages, and TOLL and DFN 8×8 surface-mount packages.
The company also will continue to expand its line-up of the DTMOSVI series beyond the already released 650V and 600V products and the new products with high-speed diodes. This will enhance switching power supply efficiency, contributing to energy-saving equipment.

Innoscience Technology will demonstrate industry-leadership at the upcoming IEEE Applied Power Electronics Conference and Exposition (APEC) 2024.
At the industrial session, Innoscience will address the exponential demand in power by datacenters due to the processing power necessitated by Artificial Intelligence (AI) applications. The paper will show that with Innoscience’s 650V InnoGaN, it is possible to make a 2kW AC/DC conversion PSU with a high power density and a peak efficiency above 96%, thereby meeting the recent stringent 80 Plus titanium efficiency rating.
Thanks to the absence of a body diode on GaN devices, a simple Totem pole PFC architecture can be implemented while still reaching high levels of efficiency. At the booth Innoscience will also showcase a 4.2kW AC/DC conversion PSU meeting 80 Plus titanium efficiency rating within a power density of 130W/in3.
Moreover, to address the 48V to 12V DC-DC power conversion inside the data center, Innoscience will present an all GaN HEMTs based 1kW 48V-12V unregulated LLC solution that features GaN power devices both at the primary side (100V devices) as well as at the secondary side (40V devices). In order to maximize the power density and simplify the circuit, the solution uses Innoscience’s recent integrated SolidGaN solution (ISG3201), which integrates an half-bridge (made by two 100V/3.2mOhm InnoGaN devices) with its driver, protection etc.. in one package. The final all GaN 1kW 48V-12 converter has a size of only 50mmx30mmx9mm, which is 70% smaller than a Silicon counterpart rated only 600W. The converter achieves a peak efficiency of 98.5%.
Dr. Denis Marcon, General Manager Innoscience Europe, comments: “Reliability is also an important consideration for data centers, because they operate 24/7 and they must guarantee continuity of service. Therefore, in this paper we will also present strong reliability data of Innoscience’s HV and LV GaN power devices, including end-of-life testing for life-time calculation which shows reliability data at the parts-per-billion level.”
Yi Sun, General Manager Innoscience America comments: “Innoscience today has one of the widest portfolio of GaN power device solutions covering 30V to 700V applications, a family of GaN discrete available in standard packages (e.g. QFN, FCQFN, TO252 etc..) as well as integrated GaN IC solutions that include in one chip the GaN FET, the driver, protections etc.”
Visitors to the Innoscience booth at APEC will also see new products, such as the NV100FQ030A, a 100V bidirectional IC that can be employed to deliver high efficiency in applications including battery management systems, high-side load switching in bidirectional converters, and various switching circuits in power systems.
Yi Sun, adds: “Innoscience is leading the GaN industry with many new products that are industry firsts. That is why our devices are finding applications in all markets, from consumer chargers through industrial and communications and into the automotive sector. Join us at booth 1543 to find out more.”
