controlled avalanche rectifiers

BYX105G; BYX106G;

BYX107G; BYX108G

FEATURES

• Glass passivated

• High maximum operating temperature

• Low leakage current

• Excellent stability

• Guaranteed avalanche energy absorption capability

• Recovery times ranging from 600 to 50 ns

• Soft-recovery switching characteristics

• Compact construction.

APPLICATIONS

• High-voltage power supply units in, for example, X-ray

or radar systems.

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.
