概述

Description

BC847BPN-QX is a small-signal NPN transistor in a SOT-23 package, part of the BC847 family. It is intended for general-purpose switching and amplification in low-power circuits.
Key points:
- Vceo: up to 45 V; Ic: up to 100 mA
- Gain (hFE): broad range (roughly 110–800 depending on Ic and temp)
- -QX suffix denotes a specific packaging/lot variant (e.g., tape/reel, RoHS-compliant); check the datasheet for exact meaning
- RoHS-compliant and widely used in consumer electronics
For exact electrical specs, pinout, and thermal data, consult the BC847BPN-QX datasheet from the manufacturer.

Features

BC847BPN-QX features (concise):
- NPN general-purpose small-signal transistor
- SOT-23 package (3 leads)
- Vceo = 45 V; Ic max = 100 mA
- Gain (hFE) group B: ~200–450 (at Ic ≈ 2 mA)
- Low Vce(sat): ~0.2 V (Ic ≈ 2 mA, Ib ≈ 0.4 mA)
- -55°C to +125°C operating temperature
- Pb-free, RoHS compliant; tape & reel packaging (QX)
- Suitable for amplification and switching; complements BC857 (PNP)

Package

SOT-23 (SOT-23-3) surface-mount package. The “-QX” denotes the specific packaging/reel variant for the BC847BPN transistor (Pb-free).

Pinout

- Pin count: 3 (SOT-23-3)
- Function: Small-signal NPN transistor (general purpose for switching/amplification)

Manufacturer

Manufacturer: Nexperia.
What kind of company: Nexperia is a Dutch multinational semiconductor company specializing in discrete components (transistors, diodes, etc.) and related technologies, supplying parts for automotive, industrial, and consumer electronics worldwide.

Application
