Product details

650 V / 20 A SiC Schottky — zero-recovery switching

The Infineon IDW40G65C5BXKSA2 is a silicon carbide Schottky diode from the CoolSiC+ series, rated 650 V reverse voltage and 20 A average forward current in a through-hole TO-247-3 package. This is the main reason designers pick SiC over ultrafast silicon in hard-switched PFC, LLC resonant converters, and high-frequency boost stages.

Forward drop and thermal headroom

Maximum forward voltage is 1.7 V at 20 A. Reverse leakage at 650 V is 210 µA.

Package and mounting — TO-247-3

The PG-TO247-3 package uses the standard TO-247 footprint with three through-hole leads. No exposed paddle to solder; the tab is electrically live (cathode potential), so the heatsink must be isolated or the mounting hole kept clear.

It is RoHS3 compliant (lead-free).

Frequently asked questions

Is IDW40G65C5BXKSA2 compatible with high-frequency power conversion?

Yes — the zero reverse recovery time (trr = 0 ns) eliminates the stored-charge switching loss that limits ultrafast silicon diodes. This makes the part well suited for hard-switched topologies like PFC and LLC converters operating above 100 kHz.
