Gate Drivers

isolated gate driveroptocouplerSMD85 kVrms isolation2.5 A peak outputUVLO

AT3120-CuH-S is an SMD8 isolated gate-driver optocoupler for driving power-transistor gates from a 15 V to 30 V isolated supply.

Best for

  • Isolated MOSFET gate drive
  • IGBT gate drive
  • Industrial inverter and motor-control circuits

Avoid if

  • Applications requiring an output supply below 15 V
  • Designs requiring verified safety approvals not stated in the datasheet
  • Circuits needing a specified negative gate-drive output

Check before use

  • Confirm input LED drive current
  • Place output-side decoupling close to VDD and VSS
  • Validate peak output current with the actual gate charge and resistor
