概述

Description

BC856B is a PNP small-signal transistor in the BC856 family (complements BC846B). It’s a general-purpose device for low-power switching and amplification.
Key points:
- Packages: available in through-hole TO‑92 and SOT‑23 (SMD).
- Electricals (typical): Vceo around -45 V; Ic up to 100 mA; Ptot about 125 mW; hFE varies widely with lot and temperature (B grade = mid-range gain).
- Usage: connect emitter to the more positive node for high-side switching or small-signal amplification in audio, control circuits, etc.
215 suffix:
- Likely a date/lot or packaging variant code rather than a different electrical spec. Functionality should be the same; confirm exact variant from the specific datasheet or supplier marking.
If you have the exact datasheet code (e.g., BC856B-TP, BC856B–3, etc.), I can pull precise numbers for that variant.

Features

BC856B is a general-purpose PNP small-signal transistor (complement to BC846) with gain grade B.
Key features:
- Type: PNP, high-gain small-signal transistor
- Gain: hFE ≈ 200–450 at Ic = 2 mA (grade B)
- Collector current: Ic up to 100 mA
- Voltage ratings: Vceo up to 45 V; Vebo up to 5 V
- Power: Ptot ≈ 125 mW (SOT-23); higher in TO-92 package
- Temperature range: -55°C to +125°C
- Packages: SMT SOT-23 and through-hole TO-92 (also available in other small packages)
- Uses: general-purpose amplification and switching, low-noise applications
Notes: BC856B is the PNP counterpart to BC846 and is commonly used where a complementary NPN (BC846) is needed.

Package

BC856B,215 denotes the BC856B PNP small‑signal transistor in an SOT‑23 (SOT‑23‑3) surface‑mount package; the “,215” is the manufacturer’s packaging/ordering code (tape‑and‑reel).

Pinout

Pin count: 3 pins.
Function: BC856B (suffix ,215 denotes a specific manufacturer/package code) is a PNP small‑signal bipolar junction transistor used for general‑purpose switching and amplification. Typical uses: low‑noise amplifier stages, signal switching, and general analog circuits. Pinout depends on package (e.g., SOT‑23), so consult the device datasheet for exact pin numbering (emitter, base, collector).

Manufacturer

- Manufacturer: Nexperia
- What kind of company: A global semiconductor company that designs and manufactures discrete components (transistors, diodes, etc.) and related ultra-high-volume semiconductor devices.

Application

BC856B is a general‑purpose PNP small‑signal transistor (low noise). Applications: audio/instrumentation signal amplification and preamplifiers; sensor readouts and signal conditioning; small‑signal switching and driver stages; high‑side switching in simple circuits; suitable for portable/battery-powered equipment; often used with BC846/BC856 complementary pairs for push‑pull or differential configurations.

Equivalent

Common equivalents for the PNP BC856B (small‑signal transistor): BC857B, BC557B (through‑hole), BC556B/BC558B (related PNP variants), and 2N3906 / MMBT3906 (widely available PNP small‑signal). Always verify pinout, Vceo, Ic and hFE before substituting.
