Product specification

High-voltage car ignition diodes

BYX134GP

FEATURES

• Glass passivated

• High maximum operating

temperature

• Low leakage current

• Excellent stability

• Guaranteed avalanche energy

absorption capability.

APPLICATIONS

• Car ignition systems

• Automotive applications with

extreme temperature

requirements.

DESCRIPTION

Rugged glass package, using a high

temperature alloyed construction.

The SOD107A 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.
