# BTA26-800CWRG

**JSMSEMI** · TRIACs · TO-3P

BTA26-800CWRG 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 A1 (MT1) of the triac, the current return terminal, rated for 25 A average on-state current at Tc=105°C. |
| 2 | A2 | passive | Main terminal A2 (MT2) of the triac, also connected to the tab, with repetitive peak off-state and reverse voltage of 800 V. |
| 3 | G | input | Gate trigger input operating in 4 quadrants, with gate-trigger current of 35 mA max (quadrants I to III) and 50 mA max (quadrant IV) at VD=12 V, RL=33 Ω. |
