Expert insights on thyristor and diode module selection
For high-temperature applications, we recommend SEMIPACK modules with advanced gate circuits that maintain consistent trigger characteristics across extended temperature ranges. The latest generations incorporate optimized gate drive requirements reducing control complexity.
When designing for high-repetitive surge currents, the latest SEMIPACK 6 generation features improved surge current handling capability. This is particularly important in welding and power supply applications where load variations are common.
For applications with inductive loads, consider modules with integrated RC snubber circuits. These provide protection against voltage transients while simplifying system design and reducing external component count.
