BTB16Q-600BW

FUXINSEMI · Thyristors (SCR)/Modules · TO-263

BTB16Q-600BW from FUXINSEMI, 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 A1 passive Main terminal 1 (A1) of the triac, the lead on the circuit diagram's lower terminal; the part is rated for IT(RMS) 16 A and VDRM/VRRM 600 V (600BW).
2 A2 passive Main terminal 2 (A2), connected to the uninsulated mounting tab; the middle lead is absent from the package, and the part is rated for IT(RMS) 16 A and VDRM/VRRM 600 V.
3 G input Gate trigger input; IGT is at most 50 mA (BW grade) and VGT is at most 1.3 V in quadrants I-II-III at VD=12 V, RL=33 Ω, and peak gate current IGM is 4 A.
