NXP USA Inc. BT149B-126 is a sensitive gate Silicon Controlled Rectifier (SCR) designed for general-purpose switching applications. This component features a repetitive peak off-state voltage of 200V and an average on-state current of 500mA, with a maximum RMS on-state current of 800mA. The BT149B-126 exhibits a gate trigger current (Igt) of 200 µA maximum and a gate trigger voltage (Vgt) of 800mV maximum, facilitating triggering from low-power control circuits. Its hold current (Ih) is rated at 5mA maximum, and the off-state current is 100 µA maximum. Non-repetitive surge current handling is 8A and 9A at 50Hz and 60Hz respectively. The device is packaged in a TO-92-3 through-hole configuration, supplied in Tape & Box (TB) packaging. This SCR is suitable for use in industrial control, power switching, and lighting control systems.
