Product specification
High-voltage car ignition diode
BYX135GL
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 SOD119AD 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.
