Descripción general

Description

BC857C is a general‑purpose PNP transistor in the BC857 family (complement to BC847). The “C” denotes the highest gain group.
Key specs (typical):
- Vceo: ≈ -45 V; Vcbo ≈ -50 V; VeBo ≈ -5 V
- Ic max: ≈ -500 mA
- Ptot: ≈ 625 mW
- DC current gain hFE: ≈ 420–800 (group C)
Package/pinout:
- TO‑92 through‑hole (flat face toward you: E–B–C). SMD (SOT‑23) variants use the same general pin arrangement.
Applications:
- General-purpose switching and small-signal amplification
- Used where a PNP device is needed (emitter at higher potential than base)
Operating note:
- Turns on when base is about 0.6–0.7 V below the emitter
- Saturation, biasing, and thermal performance follow typical small-signal transistor practices
If you need, I can tailor this to a specific package or datasheet.

Features

BC857C features (general-purpose PNP transistor)
- Type: PNP, general-purpose transistor (complement to BC847)
- Gain: Hfe ~ 420–800 (Grade C) at Ic ≈ 2 mA
- Collector current: Ic max = 100 mA
- Voltage ratings: Vceo = 45 V; Vebo ≈ 5 V
- Package: TO-92 (through-hole) and also available in SOT-23; RoHS/Pb-free
- Temperature range: -55 °C to +150 °C
- Applications: switching and amplification in low-power circuits
- Packaging/marking: widely available, suitable for through-hole and small-signal surface-mount designs
Notes: BC857C is a high-gain, low-power PNP transistor suitable for general-purpose amplification and switching.

Package

The BC857C,215 is supplied in a SOT‑23 (3‑pin) surface‑mount package. The “,215” suffix denotes the tape‑and‑reel packing code.

Pinout

- Pin count: 3 pins
- Function: BC857C is a PNP small-signal general-purpose transistor (used for amplification or switching). The “215” is a lot/date code and does not change the device’s function.

Manufacturer

Manufacturer: Nexperia (originally Philips Semiconductors/NXP).
Nexperia is a Dutch multinational semiconductor company that designs and manufactures discrete devices (such as transistors), logic, and MOSFETs, along with diodes and related components.

Application

BC857C is a general‑purpose PNP small‑signal transistor (high‑gain variant).
Applications:
- Low‑noise, small‑signal amplification (audio, sensor preamps)
- Switching and digital logic drivers (pull‑ups/pull‑downs, high‑side switches)
- Biasing and level‑shifting in analog circuits
- Emitter‑follower/output driver stages for moderate loads
- Complement to BC847/NPN in complementary push‑pull stages

Equivalent

BC857C is a PNP general‑purpose small‑signal transistor (TO‑92). Common equivalents:
- BC857A/B (same family, different gain)
- BC856, BC557 (PNP counterparts with similar specs)
- Through‑hole substitutes: 2N3906, 2N2907
- SMD equivalents: MMBT3906, PMBT3906 (SOT‑23)
Note: check pinout and gain/specs for replacements.
