Automotive Alternator Diode
SG-17VLEF Series
Data Sheet
Description
The SG-17VLEF series are the rectification diodes
designed for high efficiency alternator circuit of
automotives, and have zener characteristics with high
surge capability.
The package is a press-fit type, and has high heat
release capability and high reliability for high
temperature and humidity environment. In addition, the
bridge circuit can be configured easily in small area by
using suffix “S” type and suffix “R” type of reverse
polarity type.
Features
TJ = 200 °C Capability Suitable for High Reliability
and Automotive Requirement
Thermal Fatigue Capability: 5,000 cyc.
