Utilizing the photo-sensitive nature of silicon, VMI has created a line of hermetically sealed, high-reliability, high-voltage optocouplers and opto-diodes in versions that can be assembled in series configuration for additional standoff voltage capability — used for Mass Spectrometry, Military and Aerospace.

Available in a clear molded package, VMI’s 10kV and 20kV version optocouplers are fabricated with two infrared LEDs. VMI’s 25kV optocoupler OC250 is assembled in shell with enough isolation to allow it to be operated in air without the need for additional insulation. All optocouplers are rated for 25kV isolation voltage between the LEDs and the high voltage diode.

For applications that require more custom mechanical configurations or electrical characteristics, VMI has provided customers with the option of high voltage diodes in a clear epoxy package without the embedded LEDs. These opto-diodes are available in 10kV and 15kV.
