Littelfuse Inc. EC103B3 is a sensitive gate Silicon Controlled Rectifier (SCR) with a repetitive peak off-state voltage of 200V. This through-hole component, packaged in a TO-92 (TO-226-3) case, offers an RMS on-state current handling capability of 800mA and an average on-state current of 510mA. Key parameters include a maximum gate trigger current (Igt) of 500 µA and a maximum gate trigger voltage (Vgt) of 800 mV. The device exhibits a low leakage current with a maximum off-state current of 1 µA and a hold current (Ih) of 8 mA. It is rated for non-repetitive surge currents of 16A and 20A at 50Hz and 60Hz respectively. Operating temperature range is from -40°C to 110°C. This SCR is suitable for applications in power control and switching circuits across various industrial and consumer electronics sectors.
