FDA70N20 Frequently Asked Questions (FAQ)

  • The maximum SOA for the FDA70N20 is typically defined by the device's voltage and current ratings. For the FDA70N20, the maximum voltage rating is 700V and the maximum current rating is 20A. However, the actual SOA may be limited by the device's thermal characteristics and the application's specific requirements.

  • Proper thermal management is crucial for the FDA70N20. Ensure good thermal contact between the device and the heat sink, and use a thermal interface material (TIM) if necessary. The heat sink should be designed to dissipate the maximum expected power loss, and the device's thermal resistance (RθJA) should be considered in the design.

  • The recommended gate drive voltage for the FDA70N20 is typically between 10V and 15V. However, the optimal gate drive voltage may vary depending on the specific application and the desired switching performance. A higher gate drive voltage can result in faster switching times, but may also increase power consumption.

  • To protect the FDA70N20 from overvoltage and overcurrent conditions, consider using a voltage clamp or a surge protector to limit the voltage across the device. Additionally, a current sense resistor and a fuse or a current limiter can be used to detect and respond to overcurrent conditions.

  • For optimal performance and reliability, the PCB layout should minimize parasitic inductance and capacitance. Use a solid ground plane, keep the gate drive traces short and wide, and ensure good thermal conductivity between the device and the heat sink. Additionally, consider using a Kelvin connection for the gate drive to reduce noise and improve switching performance.
