Power MOSFET

Overview

Microsemi, a leader in military and commercial aerospace semiconductors, offers a large portfolio of MOSFETs, including Power/Military MOSFETs in hermetic packaging to further support the needs of high reliability customers. These devices are DLA qualified and offer great value to HiRel Customers and mission critical applications. All these QPL devices come in JAN, JANTX, JANTXV, JANS qualification levels. Commercial grade is also available. For more information refer to  Power/Military MOSFETs (837.2 kB)

For Industrial applications,  Power MOS 8™ is Microsemi's latest family of high speed, high voltage (500-1200 V) N-channel switch-mode power transistors with lower EMI characteristics and lower cost compared to previous generation devices. These new MOSFETs / FREDFETs have been optimized for both hard and soft switching in high frequency, high voltage applications rated above 500 W. There are 2 product types in the Power MOS 8™ MOSFET family:

1) MOSFET
2) FREDFETs have a fast recovery body diode characteristic, providing high commutation dv/dt ruggedness and high reliability in ZVS circuits.

Quiet Switching
The new Power MOS 8™ series is a result of extensive research into quiet switching. Input and reverse transfer capacitance values as well as their ratio were set at specific values to achieve quiet switching with minimal switching loss. The Power MOS 8™ series of devices are inherently quiet switching,  table when connected in parallel, very efficient, and lower cost than previous generations.

Body Diode Options
As with previous generation products, Power MOS 8™ MOSFETs and FREDFETs are available in all voltage ratings. A FREDFET is a MOSFET with a faster recovery intrinsic body diode. This results in improved reliability in ZVS circuits due to shorter minority carrier lifetime and increased commutation dv/dt ruggedness. If a fast recovery body diode is not needed, MOSFET versions are available.
