HV Opto-Couplers

Opto-couplers are used as switches or isolated linear regulators.


How it works:

To create a high voltage (HV) opto-coupler, the transistor is replaced by a HV diode. Inside the opto-coupler, the diode is positioned so, that light from the LED is directed towards the diode junctions. The diode junctions are sensitive to light. The brighter the light, the higher the diode leakage current.



  • HV power supply designs
  • High isolation or remote sensing capabilities



  • High voltage operation
  • High isolation
  • Configurable as a current or voltage regulator
