**DIYI Elec Tech** · Fast Recovery / High Efficiency Diodes · TO-252

SFD1060S from DIYI Elec Tech, 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 | A | passive | Anode lead; forward-biased toward cathode tab; supports up to 10 A average forward current (TC = 100 °C) with 1.4 V typical / 1.6 V max forward voltage at 10 A. |
| 2 | A | passive | Anode lead (internally connected to Pin 1); same electrical node as the left anode lead. |
| 3 | K | passive | Cathode / heatsink tab; maximum recurrent peak reverse voltage 600 V (VRRM); maximum DC reverse current 10 µA at TJ = 25 °C / 500 µA at TJ = 125 °C; thermal resistance junction-to-case RθJC = 4.6 °C/W. |

## CAD (KiCad official)

- Symbol: `SFD1060S`
- Footprint: `Package_TO_SOT_SMD:TO-252-2`
- 3D model: TO-252 (KiCad packages3D, STEP)
- 3D model files: `sfd1060s-etched.step` / `sfd1060s-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sfd1060s.step` / `sfd1060s.glb` are the bare package body.
