onsemi Single, Pre-Biased Bipolar Transistors NSBC124EMXWTBG

NSBC124EMXWTBG is an NPN bias resistor transistor in the XDFNW3 package, designed for digital switching and IC input control. It integrates a 22 kΩ series base resistor and a 22 kΩ base-emitter resistor, reducing external component count. The device supports a maximum collector-emitter voltage of 50 V and a collector current of 100 mA, with a power dissipation of 450 mW at 25°C. Junction temperature ranges from -65°C to +150°C. The part is AEC-Q101 qualified, RoHS compliant, and features a wettable flank for automated optical inspection. Its input voltage (on) is 1.6 V typical at 5 mA collector current, with a collector-emitter saturation voltage of 0.25 V max at 10 mA collector current and 0.3 mA base current.
