Toshiba TK042N65Z5 and TK095N65Z5 power MOSFETs

Toshiba has added power MOSFETs with high-speed diodes to its latest-generation DTMOSVI series with a super junction structure. The first two products, TK042N65Z5 and TK095N65Z5, are 650 V N-channel power MOSFETs in TO-247 packages.

Applications include industrial equipment, switching power supplies (data centre servers, communications equipment, etc), EV charging stations, power conditioners for photovoltaic generators and uninterruptible power systems.

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 and an 88% reduction in reverse recovery charge, according to values measured by Toshiba.

A reference design, ‘1.6 kW Server Power Supply (Upgraded)’, that uses TK095N65Z5 is available on Toshiba’s website. The company also offers tools that support circuit design for switching power supplies.
