Product specification

Ultra fast low-loss

controlled avalanche rectifier

BYW28 series

FEATURES

• Glass passivated

• High maximum operating

temperature

• Low leakage current

• Excellent stability

• Guaranteed avalanche energy

absorption capability.

DESCRIPTION

Rugged glass SOD115 package,

using a high temperature alloyed

construction.

The package is hermetically sealed

and fatigue free as coefficients of

expansion of all used parts are

matched.
