Product details

Pre-biased NPN in a tiny SOT-883 package

The BCR 135L3 E6327: The Infineon BCR 135L3 is an NPN pre-biased digital transistor with two integrated resistors (10 kΩ base, 47 kΩ emitter-base) that eliminate the external bias network. The SOT-883 (PG-TSLP-3-4) package handles collector currents up to 100 mA and blocks 50 V, with a transition frequency of 150 MHz.

Active production — no obsolescence headache

Infineon lists the BCR 135L3 as Active.

Saturation voltage is specified at 300 mV maximum with 500 µA base current and 10 mA collector current — well within the Vce(sat) budget for a typical low-side switch driving a relay coil or an LED string. The 100 nA collector cutoff keeps leakage negligible at high temperature, which matters if the load is a high-impedance input.

Frequently asked questions

Can BCR 135L3 replace BC848?

Not directly — the BC848 is a standard NPN transistor with no internal bias resistors. The BCR 135L3 includes a 10 kΩ base resistor and a 47 kΩ emitter-base resistor, so the circuit would need to be designed for those bias conditions. If the original design used external resistors, the BCR 135L3 can replace the BC848 plus those two passives, saving board space.
