Description

BC847B-QR is a general‑purpose NPN small‑signal transistor in a SOT‑23 package (RoHS; tape-and-reel packaging, suffix “-QR”). It’s the BC847 family, with the B gain grade (higher current gain than A, lower than C).
Key specs (typical):
- Vceo: 45 V; Ic max: 100 mA; Ptot ≈ 250 mW
- hFE (gain): ~200–450 (group B, at Ic ≈ 2 mA)
- ft: on the order of hundreds of MHz (suitable for small-signal amplification and switching)
- Pinout (SOT‑23): Pin 1 Emitter, Pin 2 Base, Pin 3 Collector
Applications:
- General-purpose amplification and switching in low-power circuits
- Signal buffering, level shifting, and small-signal interfacing in consumer electronics, instrumentation, etc.
Notes:
- BC847B excels in simple, low-current you can bias with a resistor network.
- The “-QR” suffix mainly indicates packaging (tape/ reel) and RoHS compliance; electrical characteristics are the same as other BC847B parts.

Features

BC847B-QR is a general‑purpose NPN silicon transistor in SOT‑23 (QR = Tape & Reel, RoHS Pb‑free) packaging. Key features:
- NPN, small-signal switching/amplification
- Vceo: 45 V; Ic max: 100 mA
- DC current gain hFE: 200–450 (group B)
- Low-noise performance for audio/signal paths
- Pd max: ~250 mW; wide operating temperature (-55 to +150 °C)
- RoHS-compliant, Pb-free; QR indicates Tape & Reel packaging
Suitable for compact, surface-mount switching and amplification tasks.

Package

BC847B-QR is in the SOT-23 three-pin surface-mount package.

Pinout

3 pins. It is a general-purpose NPN transistor (SOT-23 package) used for switching and small-signal amplification.

Manufacturer

- Manufacturer: Nexperia.
- What kind of company: A Dutch multinational semiconductor company specializing in standard discrete components (transistors, diodes, MOSFETs) and related logic devices; formed as a spin-off from NXP/Philips.

Application

BC847B-QR is a general-purpose NPN transistor (SOT-23). Applications: small-signal amplification and fast switching; buffering and level shifting for microcontroller interfaces; LED/relay driver circuits; sensor interfacing and signal conditioning; audio preamps and other low-noise front-end stages; switching regulators and other generic switching tasks.

Equivalent

Equivalents (NPN, similar specs in SOT-23 or TO-92):
- MMBT3904 (SOT-23) – e.g., Onsemi/Diodes Inc variants
- MMBT3904LT1G (Onsemi)
- 2N3904 (TO-92, through-hole)
- BC847B (other vendors’ SOT-23 versions in the same BC847 family; same gain grade B)
Note: exact hFE and Vceo vary slightly by manufacturer, so match as closely as possible.
