STMicroelectronics X0203NN-5AA4 is a sensitive gate Silicon Controlled Rectifier (SCR) designed for surface mount applications within a TO-261-4 (TO-261AA) package, also known as SOT-223. This component offers an 800V off-state voltage rating and a 1.25A RMS on-state current capability. Key electrical characteristics include a maximum gate trigger current (Igt) of 200 µA and a maximum gate trigger voltage (Vgt) of 800 mV, identifying it as a sensitive gate SCR. The device exhibits a hold current (Ih) of 5 mA and a low off-state leakage current of 5 µA. Non-repetitive surge current handling is rated at 22.5A and 25A for 50Hz and 60Hz respectively, with a maximum on-state voltage (Vtm) of 1.45V. Operating temperature range is specified from -40°C to 125°C. This SCR is commonly utilized in industrial control, power switching, and lighting control applications. Packaging is provided on tape and reel.
