LD432243

Overview

The Powerex LD432243 is an isolated dual Silicon Controlled Rectifier (SCR) module designed for high-power industrial applications. It features a POW-R-BLOK™ package configuration, providing robust electrical isolation and thermal management capabilities. The device integrates two SCRs within a single compact unit, rated for a peak off-state voltage of 2.2 kV. It supports an RMS on-state current of 800 A and a gate trigger current of 200 mA, ensuring reliable operation in demanding power conversion systems.

Feature Summary

• Dual SCR integration within a single isolated module structure
• High current carrying capacity with 800 A RMS on-state rating
• Robust insulation design utilizing the POW-R-BLOK™ package technology

Applications

• Industrial motor drives and variable frequency drives
• High-power DC-AC inversion systems
• Resistive and inductive load switching applications

Procurement Notes

Verify the specific datasheet revision and ordering suffixes to ensure compatibility with required thermal interface materials and mounting hardware. Confirm that the selected variant meets all necessary safety certifications and isolation voltage requirements for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when high current density and electrical isolation are critical requirements. Ensure the cooling system can handle the thermal dissipation associated with 800 A RMS operation. Verify that the gate drive circuitry can supply the specified 200 mA trigger current reliably under all operating conditions.
