BT136 from JUXING, 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 | T1 | passive | Main terminal T1 of the triac (the terminal opposite T2 in the symbol, where the gate G is referenced); the part is rated 4 A RMS on-state current and 600/800 V repetitive peak off-state voltage. |
| 2 | T2 | passive | Main terminal T2 of the triac, also connected to the TO-252 tab; the part is rated 4 A RMS on-state current and 600/800 V repetitive peak off-state voltage. |
| 3 | G | input | Gate trigger terminal; peak gate current is rated 2 A, peak gate voltage 5.0 V and peak gate power 5.0 W. |
