Procurement Notes
Verify the specific suffix DKM2MM against official Littelfuse documentation to confirm pinout and mechanical dimensions. Ensure compatibility with existing thermal management solutions, as the module requires appropriate heat sink mounting. Confirm that the 1800V rating meets the system's peak voltage requirements under all operating conditions.
Selection Notes
Select this component when a dual common cathode configuration is required for space-constrained designs. The 1800V rating suits medium-voltage industrial applications. Consider the 1.5V forward voltage drop for efficiency calculations. The low inductance package is critical for minimizing voltage spikes in fast-switching environments.
Part Context
This part belongs to the Littelfuse Rectifier Diode Module Series Package S DK line. These modules are designed for robust performance in demanding power electronics applications. The series offers various voltage and current ratings to suit different system needs while maintaining consistent packaging standards for easy integration.
Replacement Considerations
Cross-reference with other manufacturers' 1800V 200A dual common cathode modules. Verify pin compatibility and thermal resistance values before substitution. Ensure the replacement part meets or exceeds the original specifications for reverse voltage and forward current.
