Product details

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.

Frequently asked questions

What is a replacement for BCR148S?

Infineon has not published an official successor for the BCR148S. A functionally similar dual pre-biased NPN in SOT-363 from another manufacturer may serve as a substitute, but pin compatibility and bias resistor values (47 kΩ base, 47 kΩ emitter-base) must be verified against your design.
