# STPS3045CG-TR

**STMicroelectronics** · Schottky Diodes · TO-263-2

STPS3045CG-TR from STMicroelectronics, in a TO-263-2. 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 of the dual center-tap Schottky rectifier, rated 15 A average forward current per diode and 45 V VRRM. |
| 2 | K | passive | Common cathode of both diodes, also connected to the exposed thermal tab, with VRRM of 45 V. |
| 3 | A2 | passive | Anode of diode 2 of the dual center-tap Schottky rectifier, rated 15 A average forward current per diode and 45 V VRRM. |
