Overview
The TAIWAN SEMICONDUCTOR BC856B is a versatile PNP bipolar junction transistor designed for general-purpose switching and amplification tasks. Its critical operational characteristic lies in its moderate current handling capability (100mA continuous collector current) and respectable DC current gain (hFE min 220). A key design consideration when utilizing the BC856B in amplification circuits is managing its transition frequency (100MHz) to avoid signal distortion at higher frequencies, a common trade-off for cost-effective, general-purpose devices where bandwidth is not the primary design driver.
Key Features
- PNP Bipolar Junction Transistor
- Continuous Collector Current (Ic): 100mA
