概述
Description
The BC850BW is a general-purpose NPN bipolar junction transistor (BJT) in a SOT-323 surface-mount package. Key features include:
- Low voltage, low current operation (max. 45V, 100mA).
- High current gain (hFE) of 200–450 at 2mA.
- Low noise, suitable for small-signal amplification in audio/RF circuits.
- Complementary pair available with PNP BC860BW.
Common applications include amplification, switching, and signal processing in portable electronics. Its compact size makes it ideal for space-constrained designs.
