BTA41-1600B

KY · Thyristors (SCR)/Modules · TO-3P

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.
