HCPL-3120(AT) is an isolated 2.5 A gate-drive optocoupler for IGBT and power MOSFET switching with a 15–30 V output-side supply and UVLO protection.

Best for

  • Isolated low-power IGBT gate drive
  • Power MOSFET gate drive
  • Industrial inverter and UPS control

Avoid if

  • A validated package footprint has not been selected
  • A documented RoHS, REACH, or lifecycle status is mandatory

Check before use

  • Confirm 15 V to 30 V output-side supply
  • Check 2.5 A peak-output capability against gate charge and switching frequency
  • Place the required 0.1 µF VDD-to-VSS bypass capacitor close to the device
