The base resistor (R1) is 10 kOhms and the base-emitter resistor (R2) is 47 kOhms, so you get a fixed on/off threshold without needing external resistors for the bias network. This is common in switching loads like driving a relay coil, a small LED string, or as a level shifter in low-current digital interfaces. ## Key ratings — what they mean for a design Collector-emitter breakdown is rated at 50 V, and the maximum continuous collector current is 100 mA. That covers a lot of small-signal switching jobs — 12 V or 24 V industrial logic, 5 V microcontroller outputs driving a 50 mA load. The 200 MHz transition frequency means it can handle PWM up into the low-MHz range, though the pre-biased resistors limit switching speed compared to a discrete transistor pair. ## Package and footprint It comes in the tiny SC-101 / SOT-883 package — Infineon calls it PG-TSLP-3. That is a three-pin leadless package about 1.0 mm × 0.6 mm, so it saves board space but needs a decent solder-paste stencil and a microscope for hand rework. Surface-mount only, as you would expect. ## Lifecycle and sourcing Infineon lists the BCR 185F E6327 as obsolete.","metaTitle":"Infineon BCR 185F E6327 PNP Pre-Biased Transistor, 50 V","metaDescription":"Infineon BCR 185F E6327 PNP pre-biased transistor in SC-101/SOT-883 package. 50 V VCEO, 100 mA Ic, 200 MHz fT.

The closest functional alternative would be another PNP pre-biased transistor in a similar package (SOT-883 or SOT-323) with the same R1/R2 ratio of 10 kOhms / 47 kOhms — for example, the BCR 185 series includes other package variants, but check the pinout and footprint carefully.
