Descripción general

Description

BC856B-QR is a small-signal PNP transistor in a SOT-23 package. It’s part of the BC856 family (complement to BC846 NPN) and is used for low-noise signal amplification and general switching in compact, RoHS-compliant designs. The “-QR” suffix typically denotes packaging (tape-and-reel), not a different electrical spec.
Key specs (typical, varies by manufacturer):
- Vceo: up to 45 V
- Ic: up to 100 mA
- Ptot: ~250 mW
- hFE: broad range (class B), typically 100–450 depending on Ic and temperature
Pinout (SOT-23, left-to-right with flat face toward you): Pin 1 Emitter, Pin 2 Base, Pin 3 Collector. Always verify against the specific datasheet and package variant.
Common uses: high-side switching, level shifting, and small-signal amplification in compact circuits. Alternatives: BC856A/B/C variants or the BC556 family.

Features

BC856B-QR is a PNP general-purpose silicon transistor (complement of BC846). Key features:
- Package: SOT-23 (QR indicates reel/SMT packaging, Pb-free, RoHS)
- Vceo: 45 V
- Ic: up to 100 mA
- Gain: hFE group B (high gain, suitable for small-signal amplification)
- Low saturation voltage for switching applications
- Operating temp: typically -55°C to +150°C
- Applications: general switching and amplification in consumer electronics
Note: Suitable for using as a general-purpose PNP transistor in low-current signal paths.

Package

BC856B-QR is a small-signal PNP transistor in a SOT-23 (3-pin) surface-mount package.

Pinout

- Pin count: 3
- Function: PNP small-signal transistor (general-purpose) for switching and amplification in analog/digital circuits.

Manufacturer

BC856B (including parts labeled BC856B-QR) is a standard PNP small‑signal transistor made by multiple semiconductor vendors, not a single exclusive manufacturer. Common makers include Nexperia (formerly NXP), Diodes Inc., ROHM, Vishay and On Semiconductor. These suppliers are semiconductor companies that design and manufacture discrete components and analog/logic ICs (transistors, diodes, regulators, etc.) for electronics.

Application

BC856B-QR is a general‑purpose PNP transistor in SOT‑23. Typical applications: small‑signal amplification and buffering, low‑current switching, high‑side switching and level shifting, emitter‑follower and common‑emitter stages in analog/digital circuits; suitable for sensors, audio front‑ends, and microcontroller interfaces in surface‑mount designs (tape‑and‑reel).

Equivalent

BC856B-QR is a PNP general‑purpose transistor in SOT‑23 (BC856 family). Equivalents include:
- BC856B (same device in other packaging)
- BC856A/BC856C (different gain ranges)
- MMBT3906, PMBT3906, FMMT3906 (SMD PNP transistors with similar specs)
- 2N3906 (through‑hole)
Note: hFE and Vce ratings vary by variant. Check datasheets for exact fit and ensure pinout compatibility; QR denotes tape‑and‑reel packaging.
