SEMIKRON offers discrete diodes in three major packaging styles:

  • axial epoxy diodes for PCB mounting
  • easy to assembly stud screw-fit diodes, suitable for applications such as welding, battery charging, and rotating rectifiers in brushless generators thanks to their outstanding robustness
  • capsule (disc) diodes for high power applications especially automotive welding

The portfolio includes standard rectifiers with current ratings up to 7500A and fast rectifiers up to 140A. Additionally, avalanche rectifiers are also available. These allow for high voltage rectification of up to 8000V with single diodes, which can be connected in series for higher breakdown voltages.

Typical applications are general-purpose rectifiers, battery chargers, welding equipment, rotating rectifiers for brushless generators, electroplating, freewheeling diodes, high-voltage rectifiers, electrostatic filters, blocking diodes and others.
