IXYS introduces 40V high-current robust power MOSFETs

With on-state resistance as low as 1.7mΩ (sub 1mΩ Ron devices soon to be released), these TrenchT4 devices enable a reduction in the number of MOSFETs needed, especially in synchronous rectification. Paralleling multiple devices may not be necessary due to their high-current carrying capability and high power density, thereby simplifying the power system and improving its reliability at the same time.

The MOSFETs are avalanche rated as well and can withstand a junction temperature of up to 175ºC making them robust against device failures caused by voltage transients and the accidental turn-on of parasitic bipolar transistors inherent in the MOSFET structure. Also, the low reverse recovery charge of the body diode mitigates voltage overshoots and reduces electromagnetic interference (EMI).

Applications include synchronous rectification, high-current switching power supplies, battery powered electric motors, resonant-mode power supplies, electronic ballasts, Class-D audio amplifiers, electric forklifts, portable power tools and more.

These new 40V TrenchT4 Power MOSFETs are available in the following international standard size packages: TO-220, TO-263(3 or 7-lead), SOT-227 and TO-247. Some example part numbers are IXTH270N04T4, IXTP270N04T4, IXTA340N04T4-7, and IXTH340N04T4. The first two are rated at 270A and the last two 340A.
