MDD600-22N1

Overview

The MDD600-22N1 is a dual diode module from the MD#600 series manufactured by IXYS. It features a repetitive peak reverse voltage (VRRM) of 2200 V and a maximum average forward current rating of up to 883 A at a case temperature of 85°C. The device has a threshold voltage of 0.75 V and a slope resistance of 0.2 mΩ. It supports a peak non-repetitive surge current of 24.0 kA and an I²t capacity of 2.88×10⁶ A²s. The junction-to-case thermal resistance is 0.031 K/W for the whole module, with a maximum operating junction temperature of +150°C.

Feature Summary

• Dual diode configuration within a single isolated module housing
• High surge current capability with robust fusing protection characteristics
• Low forward voltage drop and slope resistance for efficient conduction
• Capable of operation across a wide temperature range from -40°C to +125°C

Applications

• Line rectifiers for transistorized AC motor controllers
• AC/DC motor control systems
• Professional light dimming applications
• Temperature control circuits

Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to ensure correct voltage grade and configuration selection. Confirm that mounting hardware specifications align with the required mechanical force ratings. Ensure thermal interface materials are compatible with the specified junction-to-case thermal resistance values for proper heat dissipation during operation.

Selection Notes

Select this component based on the required blocking voltage and continuous current ratings relative to the expected case temperature. Evaluate the thermal management requirements using the provided transient thermal impedance data. Consider the reverse recovery characteristics when designing snubber circuits to prevent device damage from excessive discharge currents or high dv/dt conditions.

Part Context

This module belongs to the MD#600 series, which includes various voltage grades ranging from 1200 V to 2200 V. The series offers different configurations such as dual diodes (MDD), anti-parallel diodes (MDA), and common cathode diodes (MDK). The MDD600-22N1 specifically represents the 2200 V rated version in the dual diode configuration.

Replacement Considerations

Direct substitutes include other modules within the same MD#600 series family, such as MDD600-20N1 or MDD600-18N1, provided the lower voltage ratings meet the application requirements. Cross-reference electrical parameters carefully before substitution.
