BT137S-600E from KTP, 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; the datasheet rates the device for 8 A RMS on-state current and 600 V VDRM/VRRM. |
| 2 | T2 | passive | Main terminal T2 of the triac (MT2), connected to the tab; the datasheet rates the device for 8 A RMS on-state current at TC≤68℃ and 600 V VDRM/VRRM. |
| 3 | G | input | Gate trigger terminal, with maximum IGT of 10 mA (quadrants I-III) and 25 mA (quadrant IV) and maximum VGT of 1 V at VD=12 V. |
