The BCR 146F E6327 carries an Obsolete lifecycle status.
Package and mounting
This is an NPN digital transistor with two bias resistors built into the SOT-723 package: 47 kOhms for the base resistor (R1) and 22 kOhms for the base-emitter resistor (R2). The pre-biased topology eliminates two external passives from the board, which matters when you are swapping a part in a tight layout or retrofitting a panel where PCB real estate is already spoken for. The 50 V collector-emitter breakdown and 70 mA maximum collector current cover low-side switching and logic-level interface jobs in industrial controls, small relays, or indicator drivers.
Package reality — SOT-723 / PG-TSFP-3
The part comes in a SOT-723 surface-mount package (Infineon calls it PG-TSFP-3). It is a three-pin, very small outline transistor.
Maximum power dissipation is 250 mW.
