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

STTH100W04CW 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; per-diode repetitive peak reverse voltage is 400 V (VRRM) and average forward current is 50 A at Tc = 120 °C. |
| 2 | K | passive | Common cathode shared by diode 1 and diode 2; the device is rated for VRRM 400 V and IF(AV) 2 x 50 A (100 A per device at Tc = 110 °C). |
| 3 | A2 | passive | Anode of diode 2; per-diode repetitive peak reverse voltage is 400 V (VRRM) and average forward current is 50 A at Tc = 120 °C. |
