Web10 jul. 2024 · Triac power dissipation. If i swap the load with another that draws P = 2.33 kW, then I becomes ~ 10 A; in this condition the triac overheats and it doesn't un-latch due to thermal runaway. To properly size the heatsink, I need to know how much power the triac is dissipating, and I realized that in the datasheet there is no such thing as an ... cupcake boxes westpackWebThyristor is a three terminal device with four layers of alternating P and N type material (three P-N junctions). The three terminals are Anode, Cathode and Gate.
