VNB28N04 datasheet by STMicroelectronics

VNB28N04 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the VNB28N04?
  The maximum operating frequency of the VNB28N04 is 100 kHz, but it can be operated at higher frequencies with reduced performance.
• How do I ensure the VNB28N04 is properly biased for optimal performance?
  To ensure proper biasing, connect the VCC pin to a stable voltage source between 4.5V and 18V, and the GND pin to a solid ground plane. Also, decouple the VCC pin with a 100nF capacitor to reduce noise.
• What is the maximum current rating of the VNB28N04?
  The maximum current rating of the VNB28N04 is 28A, but it's recommended to operate at a maximum of 20A to ensure reliable operation and minimize thermal stress.
• How do I protect the VNB28N04 from overvoltage and overcurrent conditions?
  Use a voltage regulator or a voltage clamp to limit the voltage to the recommended maximum of 18V. Also, consider adding overcurrent protection using a fuse or a current-sensing resistor to prevent damage from excessive current.
• What is the thermal resistance of the VNB28N04 package?
  The thermal resistance of the VNB28N04 package is typically around 2°C/W, but this can vary depending on the specific application and PCB design. Ensure good thermal management to prevent overheating.
