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). That means it is still available for existing production runs, but the manufacturer advises against using it in new projects. 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. Surface-mount assembly with standard reflow profiles works; no exposed pad to stitch.
