Pre-biased NPN — what the integrated resistors save you
The BCR 101T E6327 is a pre-biased NPN transistor from Infineon with two 100 kΩ resistors integrated between base and emitter (R1 and R2). This means the base bias network is already on-die — you drop two external resistors from the BOM and shrink the placement footprint to a single SC-75 package. The transistor itself is rated for a collector current of 50 mA and a collector-emitter breakdown voltage of 50 V, with a DC current gain (hFE) of 70 minimum at 5 mA, 5 V. Transition frequency is 100 MHz, so it handles low-speed switching and level-shifting in digital or analog interface circuits without issue.
Maximum power dissipation is 250 mW.
