Obsolete — sourcing through independent distribution
The BCR 148F B6327 carries an Obsolete lifecycle status.
Pre-biased NPN — integrated bias resistors simplify the BOM
This is an NPN pre-biased transistor in a SOT-723 surface-mount package (PG-TSFP-3). The base resistor (R1) and emitter-base resistor (R2) are both 47 kOhms, integrated on-chip. This eliminates two external resistors from the BOM and shrinks the board footprint for switching and interface applications where the base drive is fixed.
Rated for a maximum collector current of 100 mA and a collector-emitter breakdown voltage of 50 V, with a power dissipation ceiling of 250 mW. The DC current gain (hFE) is a minimum of 70 at 5 mA, 5 V. The 100 MHz transition frequency suits low-to-mid speed switching up to a few MHz. The Vce saturation voltage is 300 mV max at 500 µA base current and 10 mA collector current — a reasonable floor for a logic-level load driver.
SOT-723 footprint — layout and rework notes
The SOT-723 package (Infineon code PG-TSFP-3) is a three-lead, leadless surface-mount package. The small pad geometry demands careful solder paste volume control.
