What is the dependence of the load cycling capability of welding diodes on the temperature swing of the diode in a cycle?

Katja Fröhlich, Communications Manager

ABB's answer

Because of the thermal expansion of every material the device load cycling capability is always limited. Achievable number of load cycles is exponentially dependent on temperature excursion. The lifetime curve is available in our application note "High current rectifier diodes for welding applications".
