# BTA08F

**YFW** · TRIACs · TO-220F

BTA08F from YFW, in a TO-220F. 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 | T1 | passive | Main terminal 1 of the triac, which carries the on-state RMS current up to 8 A (TC ≤100°C). |
| 2 | T2 | passive | Main terminal 2 of the triac, with repetitive off-state peak voltage VDRM/VRRM of 600/800 V depending on the variant. |
| 3 | G | input | Gate trigger terminal, with gate trigger current IGT ≤5/10/35 mA (TW/SW/CW), gate trigger voltage VGT ≤1.3 V and peak gate current IGM of 4 A. |
