Package

The BF840 is typically housed in a TO-92 package type. This is a plastic, cylindrical transistor package commonly used for small signal transistors in electronic applications.

Pinout

The BF840 is a dual N-channel MOSFET designed for high-speed switching applications. It typically comes in a TO-220 package with 3 pins. The pin configuration is as follows:
1. Gate (G): This pin is used to control the MOSFET, allowing the user to turn the device on or off by applying a voltage.
2. Drain (D): This pin is where the load is connected. The current flows from the drain to the source when the MOSFET is turned on.
3. Source (S): This pin serves as the output for the MOSFET, connecting to ground or the negative side of the load.
The BF840 is commonly used in applications such as power management, motor control, and signal switching, benefiting from its low on-resistance and fast switching capabilities.

Manufacturer

The BF840 is manufactured by BFGoodrich, a company known for its tires and automotive products. Established in 1870, BFGoodrich is one of the oldest tire manufacturers in the United States and specializes in high-performance tires for various vehicles, including passenger cars, trucks, and motorsports. The company is recognized for its innovation and quality within the tire industry and is a subsidiary of the multinational corporation Michelin since 1988. BFGoodrich focuses on providing durable and reliable products, catering to both everyday drivers and automotive enthusiasts. Their reputation is built on performance, safety, and advanced technology in tire design.

Application

The BF840 is a low-noise N-channel JFET primarily used in applications such as audio signal processing, amplifiers, and electronic switches. Its low noise characteristics make it suitable for sensitive measurement equipment and RF amplifiers. Additionally, it can be employed in analog circuits for signal conditioning and in high-impedance buffers.

Equivalent

The BF840 is a low capacitance, high-speed switching MOSFET. Equivalent products include the BF861, BF872, and BF889. For applications requiring similar performance, you may also consider the BFP440, BFP640, and MPSU05. Always check datasheets for specific parameters like voltage, current ratings, and switching speeds to ensure compatibility.
