BT134-600-MS from MSKSEMI, in a SOT-89. 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 reference terminal for the 600 V repetitive peak off-state voltage (VDRM/VRRM) and the 2 A RMS on-state current rating. |
| 2 | T2 | passive | Main terminal T2 of the TRIAC, carrying the on-state current rated at 2 A RMS and the 600 V repetitive peak off-state voltage. |
| 3 | G | input | Gate terminal used to trigger the TRIAC; the peak gate current is rated at 1.8 A and the peak gate power at 4 W, with an average gate power of 0.5 W. |
