# 15S150SP

**YFW** · Schottky Diodes · TO-277

15S150SP from YFW, in a TO-277. 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 of the Schottky rectifier (leg 1); 15 A average forward current rating per diode, 150 V reverse voltage. |
| 2 | A | passive | Anode terminal of the Schottky rectifier (leg 2); 15 A average forward current rating per diode, 150 V reverse voltage. |
| 3 | K | passive | Cathode terminal (marked K), the exposed tab of the package, with 150 V maximum repetitive peak reverse voltage. |

## CAD (KiCad official)

- Symbol: `15S150SP`
- Footprint: `Package_TO_SOT_SMD:TO-277A`
- 3D model: TO-277 (KiCad packages3D, STEP)
- 3D model files: `15s150sp-etched.step` / `15s150sp-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `15s150sp.step` / `15s150sp.glb` are the bare package body.
