Product details

Pre-biased PNP — what the integrated resistors save you

The BCR 166F E6327: The BCR 166F is a PNP pre-biased transistor from Infineon, meaning a base resistor (R1) of 4.7 kOhms and an emitter-base resistor (R2) of 47 kOhms are built into the SOT-723 package. That eliminates two passives from the BOM and shrinks the board footprint for a simple digital-switch or inverter function.

50 V, 100 mA — where it fits

160 MHz transition frequency — switching speed headroom

Transition frequency is 160 MHz. Saturation voltage is 300 mV max at 500 µA base and 10 mA collector.

The SOT-723 package (also marked as PG-TSFP-3) is a three-lead body.

Obsolete — sourcing path

Infineon lists the BCR 166F as obsolete.

Frequently asked questions

Is BCR 166F E6327 obsolete and what is its lifecycle status?

Yes, Infineon classifies the BCR 166F E6327 as obsolete. No official replacement or successor part number has been published by the manufacturer.

What is the replacement or equivalent for BCR 166F E6327?

Infineon has not published a direct replacement for the BCR 166F E6327. A functionally similar pre-biased PNP in SOT-723 from another manufacturer would need to match the 4.7 kOhms base resistor, 47 kOhms emitter-base resistor, 50 V Vce, and 100 mA Ic ratings — verify pinout and resistor values against the BOM before substituting.
