EDZVFHT2R18B Frequently Asked Questions (FAQs)

  • A thermal pad on the bottom of the package should be connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
  • The device requires a stable input voltage (VIN) and a proper bias voltage (VBIAS) to operate within specifications. Ensure VIN is within the recommended range (2.5V to 5.5V) and VBIAS is set to 1.2V to 1.8V.
  • A 1uF to 10uF ceramic capacitor is recommended between VIN and GND to filter out noise and ensure stable operation.
  • Use a TVS diode or a zener diode to protect the device from overvoltage. Implement ESD protection measures such as a series resistor and a capacitor to ground on the input lines.
  • The device is rated for operation from -40°C to 125°C. However, the maximum junction temperature (TJ) should not exceed 150°C to ensure reliability.
