BTA41-1600B from KY, 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 | T1 | passive | Main terminal T1 of the triac; the BTA41-1600B rates 1600 V repetitive peak off-state voltage and 40 A RMS on-state current at Tc=110°C. |
| 2 | T2 | passive | Main terminal T2 of the triac; the device is rated for surge on-state current of 400/420 A and an operating junction temperature range of -40 to 125°C. |
| 3 | G | input | Gate terminal used to trigger the triac; gate trigger current is specified at ≤50 mA (quadrants I, II, III) and ≤100 mA (quadrant IV), with a peak gate current of 8 A and average gate power of 1 W. |
