Two PNP transistors with built-in bias resistors
The Infineon BCR185SH6327XTSA1 packs two PNP pre-biased transistors into a single SOT-363 package. Each transistor integrates a 10 kΩ series base resistor and a 47 kΩ resistor between base and emitter, so you can drive the base directly from a microcontroller or logic output without external biasing components. Collector-emitter breakdown is rated at 50 V, and each transistor handles up to 100 mA continuous collector current. Transition frequency is 200 MHz, which covers most low-frequency switching and driver applications up to a few megahertz.
NRND — plan for a production alternative
Infineon lists the BCR185SH6327XTSA1 as Not Recommended for New Designs (NRND). If you are qualifying a BOM for a new build, look at the BCR185 series siblings in the same SOT-363 footprint — the base resistor and base-emitter resistor values (10 kΩ and 47 kΩ) define the turn-on threshold, so a part with the same resistor divider ratio is the closest functional match.
SOT-363 footprint and power budget
The package is a 6-lead VSSOP / SC-88 / SOT-363 (Infineon calls it PG-SOT363-PO). Total package dissipation is 250 mW, so derating is necessary if both transistors run near 100 mA simultaneously.
