Overview
The Diotec Semiconductor BC549C is a general-purpose NPN bipolar junction transistor (BJT) designed for low-power switching and amplification applications. Its key operational characteristic is its high DC current gain (hFE) of up to 420 at 2mA, enabling sensitive signal amplification. A critical design consideration when utilizing the BC549C is managing its relatively low collector current rating of 100 mA; exceeding this limit can lead to thermal runaway and device failure, necessitating careful impedance matching and current limiting in circuit design.
Key Features
- Collector Current (Ic) Max: 100 mA
- Collector-Emitter Voltage (Vce) Breakdown: 30 V
- DC Current Gain (hFE) Min: 420 @ 2mA, 5V
- Transition Frequency (fT): 300 MHz
- Power Dissipation Max: 500 mW
- Package: TO-92 (Through Hole)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Low-noise audio preamplification stages
- General-purpose signal switching in control circuits
- Bias current generation for active filters
- Small-signal amplification in sensor interfaces
