Product details

Pre-biased NPN in an ultra-small leadless package

The BCR 139L3 E6327: The Infineon BCR 139L3 is an NPN pre-biased transistor that integrates a 22 kOhm base resistor (R1) directly in the package. This eliminates the external base resistor and saves board area, making it a compact switching solution for loads up to 100 mA collector current and 50 V collector-emitter breakdown. With a transition frequency of 150 MHz, this device handles moderate-speed switching — think PWM dimming at tens of kHz or level-shifting digital signals up to a few MHz. The package is SC-101 / SOT-883 (Infineon designation PG-TSLP-3-4), a leadless 3-pin surface-mount package with a tiny footprint.

Frequently asked questions

What is the difference between BCR 139L3 E6327 and BCR 135L3?

The BCR 139L3 E6327 and BCR 135L3 are both NPN pre-biased transistors in the same SC-101 / SOT-883 package, but they differ in the integrated base resistor value. The BCR 139L3 uses a 22 kOhm resistor, while the BCR 135L3 uses a different value (typically 10 kOhm or 47 kOhm depending on variant). Check the base resistor rating against your drive current requirements to select the correct one.

What is a pre-biased transistor?

A pre-biased transistor (also called a digital transistor or resistor-equipped transistor) integrates one or two bias resistors inside the package. For the BCR 139L3 E6327, a 22 kOhm resistor is connected between the base and the input pin, eliminating the need for an external base resistor. This saves board space, reduces component count, and simplifies PCB layout in switching applications.
