(FOR IGBT PROTECTION)

Features

Protects From Load Switching In AC Applications

For 120Vac, 240Vac and 440Vac Circuits

Fits Terminal Spacing on Most IGBTs

Fast Clamping – Subnanosecond

•

These devices will protect your IGBT in applications where it is

used in overload protection or switching ac loads. Transient

voltages produced when switching occurs in the positive one-half

of the cycle are clamped below the destruct level of the IGBT.

Unique low inductance shunt path virtually eliminates L(di/dt)

effects. Available as screened device for high reliability

applications. Includes burn-in and environmental tests.

Maximum Ratings @ 25°C

60kw peak pulse power dissipation for 120V @ 1.2/50µs

120kw peak pulse power dissipation for 240V @ 1.2/50µs

240kw peak pulse power dissipation for 440V @ 1.2/50µs

Operating and storage -55°C to +150°C

Shunt path inductance < 20nH

Duty cycle – .01% max.
