600 V power Schottky silicon carbide diode

Features

■ No or negligible reverse recovery

■ Switching behavior independent of

temperature

■ Particularly suitable in PFC boost diode

function

Description

The SiC diode is an ultrahigh performance power Schottky diode. It is manufactured using a silicon carbide substrate. The wide band gap 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.
