Semikron Diodes

Semikron offers discrete diodes in three major packaging styles; axial epoxy diodes, stud screw fit diodes and capsule (disc) diodes. Axial epoxy diodes are used for PCB mounting, stud screw fit diodes are used in applications such as welding and rotating rectifiers in brushless generators due to their robustness and simple mounting and capsule diodes are used in high power applications. Semikron's extensive range of diodes are used in standard and fast applications and are available in different case designs.

Semikron diode modules are designed for high current, uncommon topologies, natural cooling or when harsh conditions are required and feature hermetic sealing, compact cases, axial diodes for PCB mounting, rugged construction and an easy assembly.  

Semikron's product range offers standard rectifiers with current ratings up to 6000A, fast rectifiers up to 140A and avalanche rectifiers that allow high voltage rectification up to 5000V. Typical applications include: all-purpose rectifiers, welding equipment, battery chargers, electroplating, free-wheeling diodes, high voltage rectifiers, electrostatic filters, blocking diodes and rotating rectifiers in brushless generators.

With over 50 years experience in the semiconductor industry and millions of units produced every year, Semikron's portfolio provides products that are competitive, flexible and highly reliable.

Capsule Diodes

Only available as either 4000A or 6000A (at 50 and 85 Degrees Case respectively)

Available in low voltages, 200V up to 600V (Vrrm).

The low profile of these diodes ensure the lowest thermal resistance and are suited for water cooling.

Typical applications include welding and electroplating.
