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 6000A.

Discretes Benefits

Discrete components are used in a wide variety of applications. Particular benefits are achieved whenever high current, uncommon topologies, natural cooling or resistance to harsh conditions are required. The SEMIKRON portfolio includes axial leaded diodes up to 6A, diodes and thyristors in screw fit (stud) and capsule housings which range from 6000A and 8000V for diodes to 1200A and 1800V for thyristors.

  • Easy assembly
  • Hermetic sealing
  • Rugged construction

Avalanche Diodes

  • No over-voltage suppressors needed
  • Insensitive to short term reverse overloads
  • 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
  • Standard and fast types

Discretes Applications

Key applications include welding machines, battery chargers, electroplating, soft starters, DC motor control, AC controllers (e.g. for temperature control), alternators and others. With sealed cases, discrete devices are convenient for both natural convection and forced cooling, allowing for use in wider fields of application. With over 50 years of field experience and millions of units produced every year, the SEMIKRON portfolio provides options that are competitive, flexible and highly reliable.

Discretes Product Range

Discrete diodes and thyristors for low to high power applications are available in voltage classes from 200V to 8000V and current ratings from 1A to 6000A.
