The following information is intended to be used as a guide in finding replacements for discontinued Philips high voltage diodes.

Please note -

  • Not all parts are drop-in replacements. VMI recommends each application be evaluated on a case-by-case basis.
  • Where possible, VMI will gladly provide evaluation samples.
  • Please contact us if you have any questions, or would like to request a sample.
  • Check back often for product updates.

If the diode you are looking for is not on the list, Contact Us! We will help you find a replacement.
