IXYS Introduces 40V High-Current TrenchT4 Power MOSFETs

These 40V TrenchT4™ Power MOSFETs constitute a new generation of

high-current Trench devices from IXYS Corporation (NASDAQ: IXYS), a global

manufacturer of power semiconductors and integrated circuits (ICs) for energy

efficiency, power management, transportation, medical, and motor control

applications. Available at either 270A or 340A current rating, they are optimized

for synchronous rectification in switched-mode power conversion applications.

With on-state resistance as low as 1.7 milliohms (devices with less than 1

milliohm on-resistance 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 new MOSFETs are avalanche rated as well and can withstand a junction

temperature up to 175°C. They are thus robust against device failure 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).

Ideal 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, and

cordless power tools.

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.
