The STPSC4H065D is a 650 V, 4 A Silicon Carbide Schottky diode from STMicroelectronics, housed in a TO-220-2 through-hole package. Its defining characteristic is zero reverse recovery time (0 ns trr), which eliminates the turn-off loss spike and stored-charge ringing that plague ultrafast silicon diodes. This makes it a straight drop-in for any continuous-current PFC or resonant converter leg where the designer wants to shed the recovery tail without reworking the snubber network.
175°C junction – headroom for cramped layouts
Forward voltage is 1.75 V max at 4 A, and reverse leakage at 650 V is 40 µA.
Through-hole TO-220-2 – rework-friendly, no stencil needed
The TO-220-2 package (supplier device package TO-220AC) is a two-lead through-hole form with a metal tab for heatsinking. No hot-air rework profile to tune – a soldering iron and a desoldering wick are all it takes to swap one out on a prototype or repair board. The tab is the cathode (pin 2), so the mounting hole is at drain/collector potential; an insulating washer and thermal compound are needed if the heatsink is shared with other devices.
Active production – no last-time-buy clock
Listed as Active in the lifecycle status. For a BOM that needs a SiC Schottky in a TO-220-2, this is a stable line item with no imminent obsolescence risk.
