600 V power Schottky silicon carbide diode

Datasheet - production data

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.
