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.
