# SRT10L45SCS

**YFW** · Schottky Diodes · TO-252

SRT10L45SCS from YFW, in a TO-252. 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 the first Schottky leg (pin 1 in the diode symbol); each leg is rated 45 V VRRM and 10 A average forward current. |
| 2 | K | passive | Common cathode, connected to the case/tab (pin 2 in the diode symbol); 45 V maximum DC blocking voltage. |
| 3 | A2 | passive | Anode of the second Schottky leg (pin 3 in the diode symbol); each leg is rated 45 V VRRM and 10 A average forward current. |

## CAD (KiCad official)

- Symbol: `SRT10L45SCS`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `srt10l45scs-etched.step` / `srt10l45scs-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `srt10l45scs.step` / `srt10l45scs.glb` are the bare package body.
