HEXFET® POWER MOSFET
500 V olt, 1.5Ω HEXFET
HEXFET technology is the key to International Rectifier’s
advanced line of power MOSFET transistors. The efficient geometry design achieves very low on-state resistance combined with high transconductance.
HEXFET transistors also feature all of the well-established advantages of MOSFETs, such as voltage control, very fast switching, ease of paralleling and electrical parameter temperature stability. They are well-suited
for applications such as switching power supplies, motor controls, inverters, choppers, audio amplifiers, high
energy pulse circuits, and virtually any application where
high reliability is required.
The HEXFET transistor’s totally isolated package eliminates the need for additional isolating material between
the device and the heatsink. This improves thermal ef ficiency and reduces drain capacitance.
