Product details

The Infineon BCR 135 B6327 is an NPN pre-biased digital transistor — a standard switching transistor with two bias resistors integrated into the package: a 10 kΩ base resistor (R1) and a 47 kΩ base-emitter resistor (R2). This integration saves one or two external resistors per channel on the PCB, which matters when you are populating a dense board or trying to reduce pick-and-place cost on a high-volume design. It comes in a standard SOT-23-3 surface-mount package (Infineon designates it PG-SOT23).

Infineon lists the BCR 135 B6327 as obsolete.

Saturation voltage and gain — the switching performance numbers

The Vce saturation is specified at 300 mV maximum with a 500 µA base drive and 10 mA collector current — a clean, low-drop switch for logic-level loads. The 100 nA maximum collector cutoff current (ICBO) means leakage is negligible in off-state, so it will not pull a weakly driven output low.

Frequently asked questions

Where can I buy BCR 135 B6327 and what is the price?

The BCR 135 B6327 is obsolete and sourced through independent distribution. Submit an RFQ through this listing for a firm quote.

What is the replacement for BCR 135 B6327?

Infineon has not published a direct successor for the BCR 135 B6327. For a form-fit-function substitute, look for another NPN pre-biased digital transistor in SOT-23 with a 10 kΩ base resistor and 47 kΩ base-emitter resistor, rated for at least 50 V and 100 mA. The BCR 135 series includes several variants with different resistor ratios; verify the resistor values match your circuit's base drive requirements before substituting.
