概述
Description
BC859C is a general‑purpose silicon PNP small‑signal transistor from the BC859 family. The “C” grade indicates high current gain. It is the PNP complement of the BC849 and is used for amplification and switching in small-signal/analog circuits. Typical specs (many vendors): Vceo around 45 V, Ic up to ~100 mA, low noise and good hFE in the high‑gain range (grade C). Package: commonly available in SOT‑23 (surface‑mount). Applications include biasing, level shifting, and small‑signal amplification in audio/analog circuits. For exact pinout, electrical limits, and gain ranges, consult the datasheet for the specific manufacturer and lot.
Equivalent
BC859C is a PNP small‑signal transistor. Common equivalents: BC557C / BC556C (through‑hole), BC858 / BC857 (same family), and general PNP parts like 2N3906 / MMBT3906 (SMD). Always verify Vce, Ic, hFE (group C), package/pinout and noise specs before substituting.
Features
BC859C is a small-signal NPN silicon transistor. Key features:
- Low-noise, high-gain device (group C)
- General-purpose amplifier and switching transistor
- Suitable for audio preamps, sensor interfaces, and control circuits
- Collector current up to about 100 mA
- Voltage rating in the tens-of-volts range (Vceo is modest for small-signal use)
- Available in common package options (TO-92 through-hole and SMD variants)
Notes: “C” indicates the high-gain grade within the BC859 family.

Pinout
BC859C is a 3‑pin PNP small‑signal transistor. Its typical function is general‑purpose amplification and switching (high‑gain PNP, "C" = high hFE). Typical SOT-23 pinout: pin 1 = Base, pin 2 = Emitter, pin 3 = Collector. (Pinout can differ by package/manufacturer—check the specific datasheet for your device.)
