概述

Description

The BC847C-QR is a general‑purpose NPN transistor in a small SOT-23 package, from the BC847 family. The “C” grade indicates high current gain (roughly hFE ~ 420–800). It’s suitable for low‑noise signal amplification and switching.
Key specs (typical):
- Ic max: about 100 mA
- Vceo: ~45 V
- Vce(sat): ~0.2 V at light load
- Package: SOT‑23; -QR denotes a packaging/trace option (often reel/tape packaging). Check the exact meaning with the manufacturer/distributor datasheet.
Common uses:
- Small-signal amplification
- Digital switching and level shifting
- General purpose drivers in low‑power circuits
Note: The -QR suffix is a packaging/ordering detail that can vary by vendor. Always consult the specific datasheet for the exact electrical ratings and packaging.

Features

BC847C-QR features:
- NPN general‑purpose small‑signal transistor
- High gain (BC847C grade): hFE ≈ 420–800
- Collector current: Ic up to 100 mA
- Voltage ratings: Vceo = 45 V; Vebo = 5 V
- Power: Ptot ~ 250 mW
- Low noise; suitable for small-signal amplification and switching
- Package: SOT‑23, RoHS compliant
- QR suffix: Tape & Reel packaging (SMD)
- Temp range: -55°C to +150°C

Package

The BC847C-QR is supplied in a SOT-23 (TO-236AB) 3-pin surface-mount device (SMD) package.

Pinout

BC847C-QR is a 3-pin NPN general-purpose transistor in a SOT‑23 package. Typical pin functions (looking at the flat face with leads down): Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector (collector also tied to the substrate/backside pad). Function: the Base controls current flow between Collector and Emitter; the Collector is the input/high-voltage terminal and the Emitter is the output/reference (usually returned to ground). Refer to the manufacturer datasheet for exact pin orientation and mechanical drawings.

Manufacturer

Manufacturer: Diodes Incorporated.
What kind of company: Diodes Incorporated is a global semiconductor manufacturer that designs and produces discrete semiconductors, power-management devices, switching and signal ICs (transistors, diodes, rectifiers, MOSFETs and related analog/logic components) for consumer, industrial and automotive markets.

Application

BC847C-QR is a general‑purpose NPN transistor (SOT‑23) for low‑power switching and small‑signal amplification. Applications: switching loads up to ~100 mA in microcontroller interfaces; signal amplification in audio, sensors and instrumentation; level shifting/driving LEDs and small relays; general use in consumer electronics, telecom and industrial electronics (non‑automotive). The QR suffix indicates taped/reel packaging for automated assembly.

Equivalent

BC847C is a small-signal NPN (Vce ≈45 V, Ic ≈100 mA, high‑gain “C” group). Common equivalents:
- Same family: BC846C, BC848C (similar pinouts/specs)
- SMD/through‑hole general replacements: MMBT3904 / 2N3904
- Generic substitutes (verify gain/pinout): BC548, 2N2222/MMBT2222
Always check Vce, Ic, hFE, pinout and package before substituting.
