HIGH TEMPERATURE TRANSIL™
FOR AUTOMOTIVE APPLICATIONS
FEATURES
■ High performance TRANSIL designed to fit
high temperature environment like automotive
applications
■ High reliability planar technology
■ High performance in voltage regulation mode
■ Very low leakage current:
I_R max. = 5µA @ T_amb = 150°C
■ Peak pulse power: 600W (10/1000µs)
■ Fast response time
■ Unidirectinal type
■ Low clamping factor
DESCRIPTION
This high performance Transil series has been de-
signed to fit high temperature environment such as
automotive applications, using surface mount
technology. These devices are using high reliabil-
ity planar technology resulting in high performanc-
es in voltage regulation mode and low leakage
current at high temperature.
