TYP212 Datasheet, PDF (1/5 Pages) STMicroelectronics – SCR FOR OVERVOLTAGE PROTECTION

TYP 212 --->TYP 2012
SCR FOR OVERVOLTAGE PROTECTION
...FEATURES
HIGH SURGE CURRENT CAPABILITY
HIGH dI/dt RATING
HIGH STABILITY AND RELIABILITY
DESCRIPTION
The TYP 212 ---> 1012 Family uses high perform-
ance glass passivated chips technology.
These Silicon Controlled Rectifiers are designed for
overvoltage protection in crowbar circuits applica-
tion.
