Product details

Pre-biased NPN for space-constrained switching

The Infineon BCR148E6433HTMA1 is an NPN pre-biased transistor — a digital transistor that integrates two 47 kOhm resistors (R1 and R2) in a single SOT-23 package. This eliminates two external passives from the board, saving placement cost and PCB area in simple switching applications like relay drivers, LED indicators, or logic-level interface circuits.

50 V breakdown, 100 mA collector — typical low-side switch

Rated for a collector-emitter breakdown of 50 V and a maximum collector current of 100 mA, this part suits low-power, moderate-voltage switching where the load current stays under 100 mA. The 300 mV saturation voltage at 10 mA collector current and 500 µA base drive means it switches cleanly into saturation with minimal dissipation in the on-state.

Sourcing an obsolete part — what to expect

Infineon lists the BCR148E6433HTMA1 as Obsolete. If the design can tolerate a footprint change, a current-production pre-biased NPN in SOT-23 from Infineon or a competitor may be a more sustainable choice.

Frequently asked questions

What is the replacement for BCR148E6433HTMA1?

Infineon has not published a direct successor order code for the BCR148E6433HTMA1. A current-production pre-biased NPN in SOT-23 with similar 47 kOhm resistors and 50 V / 100 mA ratings may be functionally equivalent, but the pinout and electrical characteristics should be verified against the original design.

BCR148E6433HTMA1 vs BCR148 — are they the same?

The BCR148 is the base product number; the full order code BCR148E6433HTMA1 is a specific Infineon reel variant (Tape & Reel) of that base transistor. Electrically they are identical — same 47 kOhm resistors, same 50 V / 100 mA ratings. The suffix only affects packaging and shipping format.
