onsemi Single, Pre-Biased Bipolar Transistors NSBA124EMXWTBG

The NSBA124EMXWTBG is a PNP bias resistor transistor with integrated base and base-emitter resistors, designed for digital switching and IC input control. Housed in the XDFNW3 package (1.00 × 1.00 × 0.38 mm), it features a wettable flank for automated optical inspection and meets AEC-Q101 qualification for automotive applications. It operates with a maximum collector-emitter voltage of -50 V and collector current of 100 mA, with a power dissipation of 450 mW at 25°C and thermal resistance of 145 °C/W. The device is Pb-free, halogen-free, and RoHS compliant. Its internal bias resistors are R1 = 22 kΩ and R2 = 22 kΩ, with a DC current gain (hFE) of 60 minimum at IC = -5 mA and VCE = -10 V. The input voltage range for turn-on is -2.5 to -1.7 V, and turn-off is -1.2 to -0.8 V. It is packaged in tape and reel for surface-mount assembly.
