Overview

Description

BC846-QR is a general‑purpose NPN transistor in the BC846 family (Nexperia). It’s a small‑signal device used for switching and amplification in compact circuits. The “-QR” suffix is a packaging/reel designation used by some suppliers (typically SOT‑23, Tape & Reel). Key specs (BC846 family): VCEO ≈ 45 V, IC up to 100 mA, Ptot ≈ 250 mW. DC current gain hFE varies by grade: A ≈ 110–220, B ≈ 200–450, C ≈ 420–800. It’s a low‑noise transistor suitable for audio preamps, sensor front ends, and general switching. Operating temperature range is about −55 to +150 °C. Pinout depends on the exact package; check the specific BC846-QR datasheet for the correct orientation and exact hFE window. In practice, it’s similar to BC846 in other packaging and to a 2N3904 for small‑signal tasks.

Features

BC846-QR is a general‑purpose NPN transistor in SOT‑23. Key features:
- Vceo: 45 V; Ic max: 100 mA
- High current gain (hFE is grade dependent; typical in the hundreds)
- Low noise for small-signal amplification
- Suitable for switching and amplification in low-power circuits
- RoHS compliant, Pb-free; QR suffix relates to packaging/lot (check datasheet for exact packaging details)
- Temperature range typically −55 °C to 150 °C
Common uses: drivers, small-signal amplification, switching in handheld/compact electronics.

Package

BC846-QR comes in a SOT-23 (3-pin) surface-mount package.

Pinout

3 pins. It is a general-purpose NPN transistor (SMD, SOT-23) used for switching and amplification. Pinout (flat face toward you): pin 1 = Emitter, pin 2 = Base, pin 3 = Collector.

Manufacturer

- Manufacturer: Nexperia (formerly Philips/NXP Semiconductors).
- What kind of company: A global semiconductor manufacturer specializing in discrete components (transistors, diodes, MOSFETs), as well as logic and protection devices.

Application

BC846-QR is a general‑purpose NPN transistor in a SOT‑23 package. Common applications:
- Small‑signal amplification and buffering (audio preamps, sensor front‑ends, RF/instrumentation stages)
- Switching/driver stages (LEDs, relays, logic inputs) in compact consumer electronics
- Buffer/level‑shift stages in digital circuits
- Medium‑current switching up to about tens of mA (up to ~100 mA range depending on variant)
Note: Used where inexpensive, low‑noise, general NPN devices are needed.

Equivalent

BC846-QR is a small-signal NPN transistor in SOT-23. Equivalents include:
- BC846A/B/C (same device family, different hFE)
- BC847A/B/C (similar spec)
- MMBT3904 (SMD cross-reference from many manufacturers)
- 2N3904 (through-hole)
Note: check datasheets for exact hFE, Vce, and pinout.
