STTH50W03CW

STMicroelectronics · Fast Recovery / High Efficiency Diodes · TO-247-3

STTH50W03CW from STMicroelectronics, in a TO-247-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A1 passive Anode of diode 1, rated 25 A average forward current per diode with 300 V repetitive peak reverse voltage.
2 K passive Common cathode of both diodes, which is also connected to the tab, and is rated 300 V VRRM.
3 A2 passive Anode of diode 2, rated 25 A average forward current per diode with 300 V repetitive peak reverse voltage.
