What this SiC Schottky brings to the power stage
Its defining characteristic is zero reverse recovery time — listed as 0 ns trr — which eliminates the switching losses that plague silicon ultrafast diodes in hard-switched topologies. The TO-247-3 through-hole package (PG-TO247-3) handles the thermal load of a 30 A average forward current, and the 175°C maximum junction temperature gives headroom in a cramped enclosure.
No official second source or pin-compatible alternate is recorded in the Infineon CoolSiC™+ family, though other 650 V, 30 A SiC Schottkies in TO-247 exist from Wolfspeed and ST — each with its own gate-drive and thermal characteristics that require layout-level validation before substitution.
