**STMicroelectronics** · Thyristors (SCR)/Modules · TO-220AB

BTB10-800BWRG from STMicroelectronics, in a TO-220AB. 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 | Main terminal A1, the reference terminal for A2 and the gate (BTB10-800BW, 10 A IT(RMS), VDRM/VRRM 800 V). |
| 2 | A2 | passive | Main terminal A2, which is also connected to the non-insulated metal tab on the TO-220AB (IT(RMS) 10 A at Tc = 105 °C, VDRM/VRRM 800 V). |
| 3 | G | input | Gate trigger input, with IGT max 50 mA (VD = 12 V, RL = 33 Ω) and VGT max 1.3 V in quadrants I-II-III. |
