Product Overview: NXP BC847B NPN Bipolar Transistor
The NXP BC847B represents a high-quality NPN bipolar (BJT) transistor that is a fundamental component for a wide range of electronic applications. This small-signal transistor is designed for general-purpose switching and amplification tasks, offering reliable performance in a compact SOT-23 package. The BC847B is a versatile choice for designers due to its low current and low voltage capabilities, which make it suitable for use in low-power circuits.
Key Features
- Transistor Type: NPN - The BC847B is an NPN transistor, which means it is optimized for fast turn-on and turn-off times when a positive current is applied to the base.
- Package: SOT-23 - This small surface-mount package allows for efficient use of PCB real estate, making it ideal for densely packed electronic assemblies.
- Collector-Emitter Voltage (Vceo): 45V - The maximum voltage that can be applied from collector to emitter while the base is open-circuit.
- Collector Current (Ic): 100mA - The maximum continuous current that can flow through the collector of the transistor.
- DC Current Gain (hFE): 200-450 at 2mA - This range of current gain ensures that a small base current can control a larger collector current efficiently.
- Power Dissipation (Pd): 250mW - The maximum power the transistor can dissipate without exceeding the maximum junction temperature.
- Operating Temperature Range: -65°C to +150°C - The BC847B can operate effectively over a wide temperature range, making it suitable for various environmental conditions.
