Philips Semiconductors Product specification

High-voltage car ignition diode BYX134G

FEATURES

• Glass passivated

• High maximum operating

temperature

• Low leakage current

• Excellent stability

DESCRIPTION

Rugged glass package, using a high
temperature alloyed construction.

The SOD61AC2 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.

The BYX134G is marked with a black
cathode band on the body.

• Guaranteed avalanche energy
absorption capability.

APPLICATIONS

• Car ignition systems

MBK907

• Automotive applications with
extreme temperature
requirements.
