**KY** · Thyristors (SCR)/Modules · TO-92

MAC97A6 from KY, 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 | T1 | passive | Main terminal T1 of the triac (MT1), the reference terminal for gate triggering; device is rated IT(RMS) 1A at Tc=110°C and 600V VDRM/VRRM for MAC97A6. |
| 2 | T2 | passive | Main terminal T2 of the triac (MT2); repetitive peak off-state and reverse voltage is 600/800V (MAC97A6/MAC97A8) with IT(RMS) of 1A. |
| 3 | G | input | Gate trigger input; gate trigger voltage VGT ≤1.2V and trigger current IGT ≤3mA (quadrants I, II, III) or ≤7mA (quadrant IV) at VD=12V. |
