# STTH1002CT

**STMicroelectronics** · Fast Recovery / High Efficiency Diodes · TO-220

STTH1002CT from STMicroelectronics, in a TO-220. 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 (per-diode VRRM 200 V, IF(AV) 5 A at Tc = 155°C). |
| 2 | K | passive | Common cathode of the dual center-tap rectifier, also connected to the metal tab (VRRM 200 V). |
| 3 | A2 | passive | Anode of diode 2 (per-diode VRRM 200 V, IF(AV) 5 A at Tc = 155°C). |

## CAD (KiCad official)

- Symbol: `STTH1002CT`
- Footprint: `Package_TO_SOT_THT:TO-220-3_Vertical`
- 3D model: TO-220 (KiCad packages3D, STEP)
- 3D model files: `stth1002ct-etched.step` / `stth1002ct-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `stth1002ct.step` / `stth1002ct.glb` are the bare package body.
