FDH400TR Frequently Asked Questions (FAQs)

  • A 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer is recommended. This helps to dissipate heat efficiently and reduce thermal resistance.
  • Ensure that the device is operated within the recommended temperature range (up to 150°C). Use a heat sink or thermal interface material to improve heat dissipation. Also, consider derating the device's power handling at high temperatures.
  • The FDH400TR can withstand voltage stress up to 1.5 times the maximum rated voltage (400V) for a short duration (less than 1 second). However, it's recommended to operate the device within the specified voltage range to ensure reliability.
  • Use a transient voltage suppressor (TVS) or a metal-oxide varistor (MOV) to protect the device from voltage spikes and surges. Also, ensure that the device is operated within the recommended voltage range and follow proper PCB layout guidelines.
  • Store the devices in their original packaging or in a dry, cool place. Avoid exposing the devices to moisture, direct sunlight, or extreme temperatures. Handle the devices by the body, not the leads, to prevent damage.
