Application Notes for IGBTVS

Microsemi’s IGBTVSTM protector is intended for transients produced during load switching with a duty cycle not

to exceed .01%. For protecting against transients produced when IGBTs are applied as ac power switches and

over current protectors. Stored energy in the line and load produces damaging transient voltages during power

down or fault interrupt. Microsemi’s IGBTVSTM transient suppressor protects from nanosecond rise transients

with surge currents to 200A, 1.5/50µs. Typical application on a 3

power line is illustrated below.

Each control module contains IGBTs,

gate drive and two IGBTVS
