# STPS30100ST

**STMicroelectronics** · Schottky Diodes · TO-220

STPS30100ST from STMicroelectronics, in a TO-220. 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 | A | passive | Anode terminal; terminals 1 and 3 are short-circuited for the static characteristics, with repetitive peak reverse voltage VRRM of 100 V. |
| 2 | K | passive | Cathode, the common terminal connected to the mounting tab, rated for average forward current IF(AV) of 30 A at Tc = 125 °C with Rth(j-c) of 1 °C/W. |
| 3 | A | passive | Anode terminal; short-circuited to terminal 1 for the static electrical characteristics, with surge non-repetitive forward current IFSM of 300 A (tp = 10 ms). |
