Q6040J7TP from Littelfuse, in a TO-218-3. 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 | MT1 | passive | Main terminal 1, the reference terminal for all gate polarities and quadrant definitions of this 40 A triac. |
| 2 | MT2 | passive | Main terminal 2 of the 40 A triac, rated for VDRM/VRRM of 400 to 1000 V (Q6040J7 is 600 V). |
| 3 | Gate | input | Gate trigger input, with IGT max 100 mA and VGT max 2.0 V at VD = 12 V, RL = 60 ohm for the Qxx40x7 in quadrants I, II and III. |
