STTH1003S
Hight efficiency rectifier
Features
■ Ultrafast recovery
■ Low power losses
■ High surge capability
■ Low leakage current
■ High junction temperature
Description
The STTH1003S is an ultrafast recovery power
rectifier dedicated to energy recovery in PDP
applications.
It is especially designed for clamping function in
energy recovery block. The compromise between
forward voltage drop and recovery time offers
optimized performances.
