Zero-recovery SiC Schottky for hard-switched power stages
Its zero reverse recovery time (0 ns trr) eliminates the switching-loss component in hard-switched topologies — boost PFC, LLC converters, and motor-drive rectifiers — where a silicon fast-recovery diode would burn tens of watts in reverse recovery charge.
Conduction loss and thermal budget at 8 A
At the rated 8 A forward current the maximum forward voltage is 2.1 V, which gives a conduction loss ceiling of 16.8 W. The TO-252 package's exposed metal tab must be soldered to a sufficient copper area on the PCB to keep the junction below 175 °C — the rated maximum junction temperature. The 70 µA reverse leakage at 600 V is typical for a 600 V SiC Schottky and contributes negligible off-state loss.
Package and footprint — TO-252 (DPak)
The PG-TO252-3 package (DPak, 2 leads plus tab) is a standard surface-mount power package. The tab is the cathode terminal and carries the bulk of the thermal path. The land pattern matches industry-standard TO-252 footprints — no special pad geometry required.
