TLP621 Frequently Asked Questions (FAQ)

  • The recommended operating voltage range for the TLP621 is 4.5V to 30V.

  • To ensure proper biasing, connect a 1kΩ to 10kΩ resistor between the VCC pin and the anode of the optocoupler, and a 1kΩ to 10kΩ resistor between the cathode of the optocoupler and the GND pin.

  • The maximum current rating for the TLP621 is 50mA.

  • To ensure ESD protection, use a TVS diode or a zener diode with a voltage rating higher than the maximum operating voltage of the TLP621, and connect it between the VCC pin and the GND pin.

  • The typical propagation delay time for the TLP621 is 2μs.
