Overview
The onsemi BC556BG is a general-purpose PNP bipolar junction transistor (BJT) designed for linear amplification and switching applications. Its key operational characteristic is its moderate current gain (hFE) of 180 minimum at 2mA collector current, enabling it to effectively control larger currents with small base signals. A critical design consideration when utilizing this device in high-frequency circuits is its transition frequency (fT) of 280MHz; while sufficient for many audio and low-frequency control tasks, designers must be mindful of potential bandwidth limitations and parasitic effects at higher RF frequencies, often necessitating careful layout and component selection to mitigate signal degradation.
Key Features
- Collector-Emitter Breakdown Voltage (Vce): 65 V
- Continuous Collector Current (Ic): 100 mA
- DC Current Gain (hFE) Min: 180 @ 2 mA, 5 V
- Transition Frequency (fT): 280 MHz
- Power Dissipation (Pd): 625 mW
- Package: TO-92 (TO-226) Through Hole
