BT139B-600E-JSM from JSMSEMI, in a TO-263. 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 1 of the triac (pin 1, T1(1) in the package diagram), the reference terminal for gate triggering. |
| 2 | T2 | passive | Main terminal 2 of the triac (pin 2, T2(2) in the package diagram), also connected to the mounting tab; the datasheet rates the device at 600 V VDRM/VRRM and 16 A IT(RMS). |
| 3 | G | input | Gate (pin 3, G(3) in the package diagram); the datasheet gives a gate trigger current of up to 35 mA (quadrants I-III) or 70 mA (quadrant IV) at VD=12 V, IT=0.1 A, and a gate trigger voltage of up to 1.5 V. |
