The SMF150 high voltage diode features 15kV reverse voltage in the smallest package available. Measuring just 0.450" l x 0.120" w x 0.130" h (11.43mm l x 3.048mm w x 3.302mm h), it delivers 10mA of forward current, and a reverse recovery time of 100ns, all in the smallest footprint possible.

Starting with VMI's standard glass-body, hermetically sealed diodes, these devices are over-molded in a rigid epoxy. The leads are then trimmed and formed.

Design advantages include:

  • Increased creepage distance between the anode and cathode
  • Uniform and precise dimensions
  • Specially designed for use with automatic insertion equipment such as pick-and-place machines


Another advantage of VMI's SMF and SXF diodes is an improved process using film-assisted technology to produce highly repeatable and reliable molded parts with laser marking for clean easy-to-read labels and lot traceability.

This film-assisted-molding process provides a number of benefits compared to conventional molding methods, such as:

  • Increased manufacturing capacity
  • Allows for greater repetition capability and the reliable molding process produce more superior parts
  • New labeling allows for better data collection and statistical process control
  • Improves on-time product delivery
