BTB04-600BW

WEIDA · TRIACs · TO-252

BTB04-600BW 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 (the symbol shows T1 on pin 1), the current return and reference for gate triggering; rated for 4 A RMS on-state current (IT(RMS)).
2 T2 passive Main terminal 2 of the triac (the symbol shows T2 on pin 2), which withstands VDRM/VRRM of 600/800 V repetitive peak off-state and reverse voltage.
3 G input Gate trigger input; for the BW grade IGT is max 50 mA and VGT is max 1.5 V in quadrants I-II-III (VD=12 V, RL=33 Ω), with peak gate current IGM of 4 A.
