STTH20R04
High efficiency rectifier
Features
■ Ultrafast recovery
■ Low power losses
■ High surge capability
■ Low leakage current
■ High junction temperature
Description
The STTH20R04 is an ultrafast recovery power
rectifier dedicated to energy recovery in PDP
application.
It is especially designed for clamping function in
energy recovery block.
The compromise between forward voltage drop
and recovery time offers optimized performances.
