Low-Noise SSRs Meet Critical EMI Standards | DigiKey

Emrs Versus SSRSBasics of SSR OperationSSRS For Low Emi EnvironmentsConclusionThe output switch is the key part of the SSR. For an AC output relay, the output can be controlled by a triac or back-to-back silicon-controlled rectifiers (SCRs). The key advantage of the SCR solution is a fast dv/dt characteristic, particularly when the relay is turned “off”. For example, when an SSR with a triac controlling the output switches o...See more on digikey Author: Steven KeepingLittelfuse
