Market Demands
- Solid State Relays for AC applications use one Triac or two Silicon Controlled Rectifiers (SCRs) connected anti-parallel
- High reliability at high power and high temperature
- Electronics must be able to withstand high temperatures: high Tj(max) of 150°C is needed for the SCRs
- VZC and CZC switching for Low EMI
- A high power SSR uses a substrate with two SCRs connected anti-parallel mounted as bare dice
