# STPS3045CW

**STMicroelectronics** · Schottky Diodes · TO-247-3

STPS3045CW 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 VRRM 45 V, IF(AV) 15 A, IFSM 220 A for tp = 10 ms). |
| 2 | K | passive | Common cathode of both diodes (center tap), also connected to the tab; 2 x 15 A, 30 A per device at TC = 155 °C. |
| 3 | A2 | passive | Anode of diode 2 (per-diode VRRM 45 V, IF(AV) 15 A, IFSM 220 A for tp = 10 ms). |

## CAD (KiCad official)

- Symbol: `STPS3045CW`
- Footprint: `Package_TO_SOT_THT:TO-247-3_Vertical`
- 3D model: TO-247-3 (KiCad packages3D, STEP)
- 3D model files: `stps3045cw-etched.step` / `stps3045cw-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `stps3045cw.step` / `stps3045cw.glb` are the bare package body.
