Overview
Description
BC857C is a general‑purpose PNP transistor (complement of BC807), suitable for small‑signal amplification and switching.
Key specs (BC857C):
- Ic max: 100 mA
- Vceo: 45 V
- Ptot: 300 mW
- hFE: ~420–800 at Ic = 2 mA (grade C)
Package: available in TO‑92 through‑hole and SOT‑23 variants; A/B/C grading denotes gain range (C being high gain).
Common uses: emitter follower and common‑emitter amplifiers, audio preamps, and general signal switching.
About “215”: not a standard electrical suffix; likely a lot/date/SKU code from a supplier. If you have a specific datasheet or vendor for BC857C,235/215, please share it and I’ll map the exact specs to that variant.

Application
BC857C is a general-purpose PNP transistor (complement of BC847). Its high gain and low noise suit:
- Small-signal amplification in audio, sensor, and front-end circuits
- Emitter-follower or common-emitter stages for biasing and impedance matching
- Buffering, level shifting, and interfaces in digital/logic circuits
- Switching applications and drivers (relays, LEDs)
- Bias networks and DC-DC converter support
- Portable, battery-powered electronics due to moderate Vceo and low leakage
Note: “-215” may refer to packaging/variant code; core applications remain as above.
