RGEF400 Frequently Asked Questions (FAQs)

  • A thermal pad on the bottom of the device should be connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended.
  • Use a soldering iron with a temperature of 250°C to 260°C. Apply a small amount of solder paste to the thermal pad and reflow at 220°C to 240°C for 30-60 seconds.
  • The device can withstand voltage transients up to 1.5 times the maximum rated voltage (400V) for a duration of 100 ms.
  • Yes, but the device's power rating must be derated according to the temperature derating curve provided in the datasheet. Ensure the device's junction temperature does not exceed 150°C.
  • Use a TVS (Transient Voltage Suppressor) diode or a varistor in parallel with the device to absorb voltage transients and protect against EOS.
