Product specification

High-voltage soft-recovery

controlled avalanche rectifier

BYX90G

FEATURES

• Glass passivated

• High maximum operating

temperature

• Low leakage current

• Excellent stability

• Soft-recovery switching

characteristics

• Guaranteed avalanche energy

absorption capability.

APPLICATIONS

• High-voltage rectification at high

frequencies

• Sub-component for very high

voltage rectifiers, for example, in

X-ray and radar equipment.

DESCRIPTION

Rugged glass package, using a high

temperature alloyed construction.

This package is hermetically sealed

and fatigue free as coefficients of

expansion of all used parts are

matched.

The package is designed to be used

in an insulating medium such as

resin, oil or SF6 gas.
