NPN Transistor, SOT-23, 45V, 100mA, 200-450hFE

Description

The BC847B is an NPN bipolar junction transistor (BJT) packaged in a small SOT-23 surface-mount device. It's designed to handle a collector-emitter voltage of up to 45 volts and a collector current of up to 100 milliamperes (mA), with a current gain (hFE) range of 200 to 450. This transistor is typically used in a variety of general-purpose low-power applications.

  1. Transistor Type (NPN): Being an NPN transistor, it requires a positive voltage at its base relative to the emitter to conduct current from the collector to the emitter. NPN transistors are widely used in electronic circuits for amplification and switching.

  2. Package (SOT-23): The SOT-23 package is a small, three-lead, surface-mount package. It's popular in electronic projects and commercial products for its compact size and suitability for high-density PCB design.

  3. Voltage Rating (45V): The voltage rating of 45 volts indicates the maximum voltage the transistor can handle between its collector and emitter when the transistor is off, making it suitable for a variety of low to medium-voltage applications.

  4. Current Rating (100mA): The maximum collector current of 100mA makes the BC847B suitable for low-power applications, such as signal processing and small-load driving.

  5. Current Gain (200-450hFE): The current gain range of 200 to 450 indicates the transistor's amplification capability, with the collector current being 200 to 450 times the base current under specific conditions.

  6. Applications: The BC847B is versatile for use in various electronic applications including signal amplification in audio devices, digital logic circuits, and as a switch in various low-power devices. It's also common in DIY electronics and in consumer electronic products.

  7. Features: NPN transistors like the BC847B are appreciated for their efficiency in amplifying and controlling electrical signals. They are fundamental components in both analog and digital circuits, particularly where space is limited and low power consumption is desired.

The BC847B NPN transistor, with its specifications of 45V voltage rating, 100mA current handling, and 200-450hFE in a compact SOT-23 package, is an excellent choice for a wide range of electronic applications, especially where space-saving and low-power operation are essential.
