STPSC406
600 V power Schottky silicon carbide diode
Datasheet
-
production data
Features
•No or negligible reverse recovery
•Switching behavior independent of
temperature
•Dedicated to PFC boost diode
Description
The SiC diode is an ultrahigh performance power
Schottky diode. It is manufactured using a silicon
carbide substrate. The wide bandgap material
allows the design of a Schottky diode structure
with a 600 V rating. Due to the Schottky
construction no recovery is shown at turn-off and
ringing patterns are negligible. The minimal
capacitive turn-off behavior is independent of
temperature.
ST SiC diodes will boost the performance of PFC
operations in hard switching conditions.
