High Voltage Diodes

VMI offers the most complete range of high voltage diodes in the world. Axial-lead and SMD diodes range from 2kV to 20kV. All wafers are doped, diffused and metalized in our facility. We offer extensive testing to insure that our customers receive the highest quality diodes possible.

Axial-lead Glass-body Diodes

Axial-lead glass-body diodes 2kV and higher.

Ranging from 2kV to 20kV Vrwm, and 3000nS to 30nS Trr.

Surface Mount Diodes

Molded, and formed lead diodes.

Specially designed for use with automatic insertion equipment with increased creepage distance between the anode and cathode, 2kV, 3kV, 5kV and 15kV, 100nS-, 70nS, 50nS, 30nS and High Temperature, 200°C, 2kV, 3kV, and 5kV Diodes.

Now introducing the SXFL6525our improved replacement for the SM6525. The SXFL6525 is designed with 99.99% silver leads, which eliminates the need for copper leadframes and tin plating required for the SM6525. This new design keeps the same electrical characteristics, while also improving the manufacturing quality and leadtimes when compared to the SM6525.
The SXFL6525 will also continue the use of VMI’s film-assisted molding and laser marking. 
VMI’s film-assisted molding and laser marking process is utilized on our over-molded SMF and SXF diode manufacturingFilm-assisted molding improves reliability and manufacturability of parts and the addition of the laser marking includes a 2D barcode providing lot traceability for each diode produced. 

QPL Diodes

Military qualified diodes, axial-leaded and surface mount, including JANTX/JANTXV.

Hermetically sealed glass high voltage diodes are processed per MIL-PRF-19500, MIL_STD-750, and the application slash sheets, /575,/576, and /577.

Epoxy High Current Diodes

K-series – High voltage, high current epoxy diodes.

1.5 Amps to 3.0 Amps, 100nS, 200nS, 3000nS.
