**JSMSEMI** · TRIACs · TO-3P

BTA26-600BRG from JSMSEMI, in a TO-3P. 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 | A1 | passive | Main terminal 1 (A1) of the triac, the reference terminal for gate triggering; the device is rated for 25 A average on-state current at Tc=105℃. |
| 2 | A2 | passive | Main terminal 2 (A2) of the triac, also connected to the mounting tab; rated for VDRM/VRRM of 600 V. |
| 3 | G | input | Gate trigger input; IGT max is 50 mA in quadrants I to III and 100 mA in quadrant IV, with VGT max 1.3 V at VD=12 V, RL=33 Ω. |
