Controlled avalanche rectifier

BY527

FEATURES

• Glass passivated

• High maximum operating

temperature

• Low leakage current

• Excellent stability

• Guaranteed avalanche energy

absorption capability

• Available in ammo-pack.

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.
