FAQs
What is BUZ73L?
The BUZ73L is a high voltage, N-channel power MOSFET designed for use in a wide range of applications such as power supplies, motor control, and electronic switching circuits. It is known for its high voltage handling capability and low on-resistance, making it suitable for high power switching applications.
How Does BUZ73L Work?
The BUZ73L works by controlling the flow of current between the source and drain terminals using an electric field. When a sufficient voltage is applied to the gate terminal, the MOSFET allows current to flow, enabling it to act as a switch or amplifier. Its low on-resistance minimizes power loss and heat generation during operation.
How Many Pins does BUZ73L have and What are the Functions of the Pinout Configuration?
The BUZ73L is housed in a TO-220 package, typically containing three pins:
- G: Gate terminal for controlling the MOSFET.
- D: Drain terminal for the output connection.
- S: Source terminal for the input connection and reference point for the drain current.
What are the Pros and Cons of BUZ73L?
Pros:
- High Voltage Capability: Can handle high voltages, suitable for power applications.
- Low On-Resistance: Reduces power loss and heat generation during operation.
- Reliable Switching: Provides reliable switching performance in various applications.
Cons:
- Gate Drive Voltage: Requires a sufficient and controlled gate drive voltage for proper operation.
- Heat Dissipation: May require additional heat sinking or thermal management in high power applications.
Are There Any Equivalents/Alternatives to BUZ73L for Recommendation?
Some equivalents to the BUZ73L include the IRF840 from Infineon Technologies and the STP12NM50FP from STMicroelectronics.
