The TO-220-3 package (supplier device package TO-220AB) is a standard through-hole footprint. The tab is internally connected to the MT2 terminal — account for this when heatsinking or isolating the device. The Bulk packaging means loose tubes, not tape-and-reel; order quantities should reflect tube multiples if automated insertion is planned.
For a BOM line, this part is a current-production item with no imminent supply risk.
The RMS on-state current is 4 A. This is the continuous load current rating for the triac.
The maximum gate trigger current is 35 mA. The maximum gate trigger voltage is 1.5 V.
Yes. The 800 V off-state voltage provides ample margin for 240 VAC mains, including common line transients.
The BTA204-800C has a higher off-state voltage rating (800 V vs 600 V). If the circuit is designed for 600 V, the 800 V part is a drop-in replacement provided the other ratings (4 A RMS, 35 mA Igt, TO-220-3 package) match the application requirements.
