Hello, I am designing Electric Heater control circuit. My circuit has two SCR in inverse-parallel strucuture and I use both of phase angle and zero cross control. I have used SCR component model BTW69, but the issue is that I need big heat dissipating sink. Please introduce me new substitute component of BTW69, which has less power dissipation. My heater needs 2500W power, AC 220V, current is about 12A.
I would be happy if you introduce more modern approach to control Electric heater.
