BT134 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 (MT1), the current return terminal for the 2 A RMS on-state current (IT(RMS)) with VDRM/VRRM of 600 V or 800 V. |
| 2 | T2 | passive | Main terminal T2 of the triac (MT2), also connected to the tab, carrying the 2 A RMS on-state current with VDRM/VRRM of 600 V or 800 V. |
| 3 | G | input | Gate trigger terminal, with peak gate current IGM of 4 A and peak gate power PGM of 5.0 W. |
