BTB04-600CW 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 of the triac (T1(1) in the symbol), the reference terminal for gate triggering, rated for 4 A RMS on-state current. |
| 2 | T2 | passive | Main terminal 2 of the triac (T2(2) in the symbol), rated for VDRM/VRRM of 600/800 V and 4 A RMS on-state current. |
| 3 | G | input | Gate terminal (G(3) in the symbol), with trigger current IGT of 35 mA max for the CW suffix (VD=12 V, RL=33 Ω) and VGT of 1.5 V max. |
