Dual pre-biased NPN in SOT-363
The Infineon BCR148SE6433HTMA1 packs two NPN pre-biased transistors in a single 6-VSSOP / SOT-363 package.
Infineon lists the BCR148SE6433HTMA1 as obsolete.
The 50 V VCEO gives you comfortable headroom for 12 V, 24 V, and most 48 V industrial rails. The 100 mA Ic per transistor handles small relays, LEDs, and logic-level loads. With hFE minimum 70 at 5 mA and Vce(sat) of 300 mV at 10 mA, the part switches cleanly without wasting much voltage across the collector-emitter junction. The 250 mW total power limit means you need to watch the thermal budget if both transistors run near full current simultaneously.
