Single Bipolar Transistors

BC847B Description

The BC847B from MDD is a high-performance NPN bipolar junction transistor (BJT) designed for surface-mount applications. With a collector-emitter voltage (Vce) rating of 45V and a maximum collector current (Ic) of 100mA, this transistor is optimized for low-power amplification and switching in compact electronic designs. Its transition frequency of 100MHz ensures reliable performance in high-frequency signal processing, while the low Vce saturation voltage (500mV @ 5mA, 100mA) minimizes power loss in switching applications. Packaged in SOT-23 and available in Tape & Reel (TR), the BC847B is RoHS3 compliant and rated for MSL 1 (Unlimited), making it suitable for automated assembly processes.

BC847B Features

• High DC Current Gain (hFE): 200 (min) @ 2mA, 5V, ensuring efficient signal amplification.
• Low Leakage Current: Collector cutoff current (ICBO) of 100nA, enhancing power efficiency.
• Compact & Reliable: SOT-23 package with a power dissipation of 200mW, ideal for space-constrained designs.
• Fast Switching: 100MHz transition frequency for high-speed applications.
• Low Saturation Voltage: 500mV @ 5mA, 100mA, reducing heat generation in switching circuits.
• Compliance: RoHS3, EAR99, and REACH (Vendor Undefined) certified for global use.

BC847B Applications

The BC847B excels in:

• Signal Amplification: Audio preamps, sensor interfaces, and RF stages due to its high hFE and low noise.
• Switching Circuits: Relay drivers, LED drivers, and logic level shifting with low Vce(sat).
• Portable Electronics: Battery-operated devices (e.g., wearables, IoT) thanks to low leakage and compact size.
• Automotive & Industrial Systems: Non-critical control modules where 45V breakdown voltage and temperature stability are key.

Conclusion of BC847B

The BC847B stands out as a versatile, high-gain NPN transistor for low-power amplification and switching. Its combination of high frequency, low saturation voltage, and compact packaging makes it a preferred choice for modern electronics. Whether in consumer gadgets, industrial controls, or automotive subsystems, the BC847B delivers reliable performance with minimal footprint, aligning with the demands of miniaturized and energy-efficient designs.
