Thyristor Discs

Thyristors in disc housings with a voltage range of 200 V to 8000 V and a current range of 86 A to 4800 A

anchor

Overview

All discs are assembled in highly reliable, robust, and hermetic-sealed ceramic housings in order to avoid mechanical damage, as well as almost any negative environmental influences, for example, high humidity. As an extension, our product portfolio contains disc types such as light-triggered thyristors (LTT).

Key Features

  • High reliability
  • Robustness
  • Hermetic-sealed ceramic housings
  • Disc types as LTT

About

Introduction to thyristor discs

The ceramic discs offer an easy way of triggering by using laser diodes and optical fibers to avoid insulation problems between the load and trigger unit. Higher reliability thanks to fewer electronic components on high potential by using the internal protection functions (BOD and dv/dt protection). The power range covers blocking voltages from 200 V up to 8000 V and current ratings from 86 A up to 4800 A.

About thyristors

Thyristors are current-controlled power semiconductors that can block forward and reverse voltages for AC mains and conduct current in the forward direction. Therefore, thyristors are widely used in AC/DC rectifier circuits as a thyristor bridge rectifier.

Main applications

Thyristors are also widely used in industry applications such as uninterruptible power supplies (UPS), solid state relays (SSR), energy storage, and battery chargers where high blocking voltage, long-term reliability, large inrush current capabilities, and high surge current handling capabilities are required. Our thyristors are known to fulfill all these requirements.
