I have a heat sink attached to the triac. The line voltage input is VAC, the load voltage reads I have a 10K resistor from MT2 to the gate, and from the gate to neutral is a.
The triac switches on and off perfectly, but too hot. I noticed the load V datashee 12V lower than the line V, so I tried lowering the resistor value from 10K which was to allow around 12mA to the bta088-400c to 4.

As a result the load V went up to Gate voltage under a 7 amp resistive load was. Below is the link to the data sheet. Feb 25, 2. Mar 14, 20, 5, The triac will dissipate about 7W average with a 7A datawheet. What is the heatsink? Feb 25, 3.
datasyeet Nov 30, 18, 9, I suspect that the. If this is true, the only thing left to consider is the heat sink. Feb 25, 4.
Aug 21, 5, 1, If datashewt can’t get a thermocouple, you can try this test: Unplug the input AC line, put a dab of siliva on the tip of your finger and touch the tab on the triac -if its hot but doesn’t “fry spit” then its not too hot. By the way, datasheft should be located such that there is sufficient air flow. I agree with 12, it looks like the 0. You can also reduce the capacitor value to reduce the delay; perhaps the triac turning on at a lower voltage because of the reduced delay, thereby reducing turn-on losses, but that might not get you as much benefit as using a better heatsink.

At power line frequencies, TRIAC switching losses are very low no matter when you turn it on, since it turns on so rapidly. The vast majority of the power dissipation is from the forward conduction loss due to the load current flowing through its ON voltage.
