Product details

Pre-biased NPN — integrated bias resistors simplify the BOM

This is an NPN pre-biased transistor in a SOT-723 surface-mount package (PG-TSFP-3). The base resistor (R1) and emitter-base resistor (R2) are both 47 kOhms, integrated on-chip. This eliminates two external resistors from the BOM and shrinks the board footprint for switching and interface applications where the base drive is fixed.

The 100 MHz transition frequency suits low-to-mid speed switching up to a few MHz.

SOT-723 footprint — layout and rework notes

The SOT-723 package (Infineon code PG-TSFP-3) is a three-lead, leadless surface-mount package. The small pad geometry demands careful solder paste volume control.

Frequently asked questions

What is the replacement for BCR 148F B6327?

A functionally equivalent pre-biased NPN transistor with 47 kOhm integrated resistors in a SOT-723 package would be the closest match, but pin compatibility and electrical ratings must be verified against the original design.

What is the difference between BCR 148F B6327 and BCR 148S?

The BCR 148F B6327 is in a SOT-723 package (PG-TSFP-3), while the BCR 148S is typically in a SOT-23 or SOT-323 package. The SOT-723 is smaller (1.2 x 1.2 mm body) with a finer lead pitch, which affects the PCB footprint and rework method. Electrical specifications (47 kOhm resistors, 100 mA Ic, 50 V Vce) are the same across the BCR 148 family.
