• Designed and qualified for industrial level
DESCRIPTION
VS-8STH06FP 600 V series are the state of the art
tandem hyperfast recovery rectifiers: excellent switching
performance and extremely low forward voltage drop trade
off is overcome, boosting overall application performance.
Specially designed for CCM PFC application, these devices
show incomparable performance in every current intensive
hard switching application.
Optimized reverse recovery stored charge enables
downsizing of boosting switch and cooling system,
increased operating frequency make possible use of smaller
reactive elements. Cost effective PFC application is then
possible with high efficiency over wide input voltage range
and loading factor.
Plastic insulated package features easy mounting together
with not insulated parts.
