PNP pre-biased transistor with integrated bias resistors
The Infineon BCR169E6327HTSA1 is a PNP pre-biased transistor in a SOT-23-3 surface-mount package. It integrates a 4.7 kOhm base resistor (R1), eliminating the need for an external bias resistor in switching and driver applications. The device is rated for a collector-emitter breakdown voltage of 50 V and a continuous collector current of 100 mA, with a power dissipation limit of 200 mW. Its 200 MHz transition frequency suits it for low-frequency switching up to the low-MHz range.
NRND — planning for a replacement
This means Infineon is not actively promoting it for new project starts, though existing production runs may still be fulfilled through the channel. For a new BOM line, a pin-compatible PNP pre-biased transistor from the same BCR169 base family should be evaluated.
SOT-23 footprint and mounting
The device is supplied in a TO-236-3 / SC-59 / SOT-23-3 package, specifically the PG-SOT23 variant from Infineon. It is a surface-mount component intended for reflow soldering.
