Philips Semiconductors Product specification

High-voltage car ignition diode BYX135G

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 SOD61AD2is 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.
