The logic-level SCRs are suitable in all applications where the available gate current is limited (IGT < 500 µA). These are used for small motor control, detection, overvoltage crowbar protection or stand-by mode in power supplies, capacitive ignition for motorbikes and HID lamp ballasts, and pilot circuits in solid state relays. They feature optimized forward voltage drop and inrush current capability, for reduced power losses and high reliability in harsh environments.
They are available in SMD packages – SOT223, SOT23, SMB Flat, DPAK – and through-hole packages – TO92, TO202, IPAK, TO220AB, TO220-FP.

New SCR optimized for rugged circuit breaker applications
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.
