STMicroelectronics- New SCR optimized for rugged circuit breaker applications
High surge voltage 1.25 A SCR for circuit breaker
The newcomer to ST’s logic level thyristor family, the TS110-8, is dedicated to miniature circuit breakers. It enables designers to reach a very low power consumption and a high robustness design thanks to its low leakage current and its 1250 V direct surge voltage capability. It provides high off-state immunity (dV/dt=200 V/μs) that ensures the breaker does not trip in case of an electrical fast transient (EFT) on the mains. The TS110-8 is available in the through-hole TO92 package, with two pinout versions, and in the surface-mount 3-lead SMBFlat-3L package.
