# STTH1002CG-TR

**STMicroelectronics** · Fast Recovery / High Efficiency Diodes · D2PAK

STTH1002CG-TR from STMicroelectronics, in a D2PAK. 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 center-tap rectifier (VRRM 200 V, IF(AV) 8 A per diode). |
| 2 | K | passive | Common cathode of both diodes, also connected to the tab (the drawing shows only a short stub for this lead). |
| 3 | A2 | passive | Anode of diode 2 of the dual center-tap rectifier (VRRM 200 V, IF(AV) 8 A per diode). |
