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.
