Overview

Description

BC859C is a low-noise, general‑purpose PNP small‑signal transistor in a SOT‑23 package. The “C” grade indicates higher current gain within the BC859 family, making it suitable for high‑gain stages, buffers, and light switching in analog circuits.
Key specs (typical):
- Package/pinout: SOT‑23; E–B–C (pins 1–3) with the flat face toward you
- Vceo: ~45 V
- Ic max: ~100 mA
- Ptot: ~250 mW
- Gain (hFE) at Ic ≈ 2 mA: roughly 200–500 (high‑gain C grade)
- Ft: several hundred MHz
- Temp range: −55 to ~150 °C
Note: exact values vary by lot; consult the datasheet for your specific part and packaging.

Features

BC859C features:
- PNP silicon small-signal transistor
- High-gain variant (grade C)
- Collector current up to about 100 mA
- Collector-emitter voltage (Vceo) ~45 V
- Low-noise device suitable for audio/preamp stages
- Available in TO-92 plastic package (through-hole); gain grade variants also in other formats
- General-purpose, commonly used for amplification and switching tasks

Package

The BC859C is a PNP small‑signal transistor commonly supplied in the SOT‑23 (3‑lead surface‑mount) package. Some manufacturers also offer it in the through‑hole TO‑92 package. Check the specific datasheet for pinout and package code.

Pinout

- Pin count: 3
- Function: PNP general‑purpose small‑signal transistor (SOT‑23), used for amplification and switching.

Manufacturer

The BC859C is a standard PNP small‑signal transistor manufactured by multiple semiconductor companies (examples: Nexperia (formerly NXP’s discretes), Diodes Incorporated, ON Semiconductor, ROHM, Vishay, Central Semiconductor). These manufacturers are semiconductor companies that design and produce electronic components—discrete devices (transistors, diodes, MOSFETs), logic and analog ICs—and supply parts to the electronics and industrial markets.

Application

BC859C is a general-purpose, low-noise PNP transistor. Applications:
- Small-signal amplification for audio preamps and microphone circuits
- High-side switching and emitter-follower buffer stages
- Bias networks and sensor front-ends
- Instrumentation and RF/IF small-signal circuits in portable electronics

Equivalent

BC859C is a PNP small‑signal transistor (Vce ≈ −45V, Ic ≤ 100mA). Common equivalents: BC557C / BC558C (through‑hole TO‑92), BC856C / BC857C (SMD variants), and SMD MMBT5561 / MMBT857 (manufacturer equivalents). Verify package, pin‑out and hFE class before substituting.
