BT137S-800E from KY, in a TO-252. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | T1 | passive | Main Terminal 1 (MT1); bidirectional AC power terminal, conducts up to 8 A RMS at Tc = 110 °C, holding current IH ≤ 30 mA (grade E). |
| 2 | T2 | passive | Main Terminal 2 (MT2); bidirectional AC power terminal and exposed solder tab for heatsinking; VDRM/VRRM = 800 V, ITSM = 84 A (tp = 10 ms). |
| 3 | G | input | Gate trigger input; VGT ≤ 1.3 V, IGT ≤ 25 mA (quadrants I/II/III) / ≤ 70 mA (quadrant IV) at VD = 12 V, RL = 30 Ω; peak gate current IGM = 4 A. |
