MAC97A8G

FUXINSEMI · TRIACs · TO-92

MAC97A8G from FUXINSEMI, in a TO-92. 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 (MT1) of the triac, the reference terminal on the circuit diagram; the device is rated 0.8 A IT(RMS) and 600/800 V VDRM/VRRM.
2	G	input	Gate trigger input; triggers in all four quadrants with IGT max 5 mA (quadrants I-II-III) or 7 mA (quadrant IV) and VGT max 1.2 V at VD=12 V, IT=0.1 A.
3	A2	passive	Main terminal 2 (MT2) of the triac; repetitive peak off-state and reverse voltage 600/800 V, RMS on-state current 0.8 A.
