Product details

Pre-biased NPN — what the integrated resistors buy you

The BCR 146T E6327: The BCR 146T is an Infineon NPN pre-biased transistor that integrates two resistors into the package: a 47 kΩ base resistor (R1) and a 22 kΩ emitter-base resistor (R2). This eliminates two external passive components from the BOM for simple switching and interface applications — the transistor turns on when the base drive exceeds the resistor divider threshold, with no external bias network to design or place. Rated for 50 V collector-emitter breakdown and 70 mA continuous collector current, with a transition frequency of 150 MHz.

SC-75 SOT-416 footprint

Packaged in the 3-pin SC-75 (SOT-416) case — supplier device code PG-SC75-3D — this is a small surface-mount footprint suited for dense PCB layouts. The 250 mW power dissipation ceiling limits continuous current in free-air; derate per the thermal resistance for the board copper area you allocate.

Obsolete — sourcing reality

Infineon lists the BCR 146T as Obsolete. Sourcing is limited to the independent distribution channel — new-old-stock and surplus inventory only.

Frequently asked questions

What is the replacement for BCR 146T E6327?

Infineon has not published an official successor for this order code. The functionally similar BCR146T E6327 is an AEC-Q101 automotive-grade variant with the same 47 kΩ / 22 kΩ resistor values and 150 MHz fT, but it is also not an official drop-in replacement — verify the package and ratings against your design.

What are the base and emitter-base resistor values for BCR 146T E6327?

The integrated base resistor R1 is 47 kΩ, and the emitter-base resistor R2 is 22 kΩ. These set the turn-on threshold: the transistor starts conducting when the base voltage exceeds approximately 0.7 V × (R1 + R2) / R2.
