bc847b

The BC847B is one of the best NPN transistors, non-specific and general purpose ones, for both power switching and amplification. It comes in the quite small TO-92 package. Thus making it more appropriate for those applications which involve very limited yet crucial space. Often found applications of BC847B are in consumer electronics, communications equipment, and power supply circuits, as it assures reliable, efficient, and simple usage.

Key Features
Small Package: Again, the TO-92 package of the BC847B can be effectively optimized into the compact circuit designs available today. Result? This is a small space. Great for devices.
Very High Current Gain: With a feasible current gain (hFE) range of 110-800, the BC847B is effective for low-power amplification application, where boosting enhancement is important to signal generation.
Moderate Current Handling: It will support a collector current up to 100mA, meaning this transistor is well suited for low-power applications requiring little or no heat sinks or complicated cooling setup.
Voltage Rating: The collector-emitter voltage of BC847B is rated not exceeding 45V, which means this type of device fits very well with those circuits that produce fairly low voltages, thus extending the lifetime, followed often by protection in voltage spikes.
Saturation Voltage Low: The BC847B shows the low saturation voltage, which means it works at much higher efficiency with very low losses in power when driven. This leads to very little heat generation in the circuit, which finally improves overall performance.
Reliability: Its credibility as a robust and long-lasting component can be seen from the fact that it operates in almost all environmental variations and builds in extremely reliable long-term circuit designs.
