Housingless welding diodes

Best-in-class performance and lifetime

anchor

Overview

The welding industry is pushing current capability and lifetime to the limit. Our family of housingless welding diodes serves both. We designed them with improved losses for medium-frequency resistance welding and high-current rectifier applications.

Key Features

  • Forward current up to 25% higher
  • Low losses
  • Highest reliability
  • Best-in-class cycling capability

Highlights of housingless diodes

Our housingless welding diodes show extremely stable on-state behavior over a lifetime and therefore can also perfectly be used for surge protection applications. The low on-state voltage allows very high forward current up to 25% more than our current types. The power diodes focus on the best-in-class performance-to-lifetime ratio supporting a decrease in maintenance cycles. The main applications are spot-welding in the automotive industry, low-voltage electrolysis, and surge protection. The power diode generation offers the highest power cycling capability in the market. Compared to conventional devices, the lower on-state voltage of the power diodes allows 10 to 15 % higher currents. With this, you have the choice between a longer lifetime and an increased current for your application.

Dimensions of housingless diodes

The Infineon power diodes are available in standard dimensions of 38 mm, 46 mm, 56 mm and 65mm diameters with a blocking voltage of 600 V: 

38DN06B02, 46DN06B02, 56DN06B02 and 65DN06B02. Our power diode generation is ideal for extending the performance of existing designs with full mechanical compatibility.
