BTA04F

YFW · TRIACs · TO-220F

BTA04F from YFW, in a TO-220F. 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, the current return terminal relative to which the gate is triggered; the device is rated IT(RMS) 4 A (TC≤105°C) and ITSM 40 A.
2 T2 passive Main terminal T2 of the triac, rated for VDRM/VRRM of 600/800 V and IT(RMS) of 4 A (TC≤105°C).
3 G input Gate trigger terminal with IGT ≤5/10/35 mA (TW/SW/CW) and VGT ≤1.3 V in quadrants I-II-III, peak gate current IGM 4 A (tp=20us) and average gate power 1 W.
