# STPS40150CG-TR

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

STPS40150CG-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 common-cathode Schottky pair (20 A average per diode, VRRM 150 V). |
| 2 | K | passive | Common cathode of both diodes, also connected to the tab (VRRM 150 V, 40 A average per device). |
| 3 | A2 | passive | Anode of diode 2 of the dual common-cathode Schottky pair (20 A average per diode, VRRM 150 V). |
