Discrete Diodes and Thyristors

Discrete diodes and thyristors for low to high-power applications. A wide range of case designs are available in voltage classes from 200V to 8000V and current ratings from 1A to 7500A.

Discretes Benefits

Discrete components are used in a wide variety of applications. Particular benefits are achieved whenever high current, uncommon topologies, natural cooling or stability in harsh conditions are required.

The SEMIKRON portfolio includes axial leaded diodes up to 6A, diodes and thyristors in screw-fit (stud) and capsule housings for up to 7500A and 8000V and 1200A and 1800V for diodes and thyristors, respectively.

  • Easy assembly
  • Hermetic sealing
  • Rugged construction

Avalanche Diodes

  • No overvoltage suppressors needed
  • Robust in short reverse overload conditions
  • High blocking voltages possible without static or dynamic voltage sharing circuits

Discretes Key Features

  • Recommended for forced air and water cooling
  • Compact case with high current capability
  • Stud and disc types: forward drop selections available for easy paralleling
  • Axial diodes for PCB mounting
  • Available in standard and fast versions

Discretes Applications

Key uses include welding machines, battery chargers, electroplating, soft starters, DC motor control, AC controllers (e.g. for temperature control), alternators and many more. With sealed cases, discrete devices are convenient for both natural convection and forced cooling, allowing for a broader range of applications. With over 50 years of experience in the field and millions of units produced every year, the SEMIKRON portfolio delivers competitive, flexible and highly reliable products and solutions.
