BTB06-600CW from WEIDA, in a TO-252. 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 1 (T1), the triac's current-carrying terminal on the gate side, for a device rated 6 A IT(RMS) and 600 V VDRM/VRRM. |
| 2 | T2 | passive | Main terminal 2 (T2), the other current-carrying terminal of the 6 A, 600 V triac. |
| 3 | G | input | Gate trigger input; for the CW grade IGT is max 35 mA (VD=12V, RL=33Ω) with VGT max 1.5 V in quadrants I-II-III. |
