MDD255-16N1

Overview

The IXYS MDD255-16N1 is a high-power silicon rectifier diode module designed for demanding industrial applications. It features a peak repetitive reverse voltage (Vrrm) of 1600 V and a maximum continuous forward current (If) of 270 A. The device utilizes the Y1-CU package with three pins and panel mounting configuration. Key electrical parameters include a maximum forward voltage (Vf) of 1.4 V, a peak reverse current (Ir) of 30 mA, and a non-repetitive peak forward surge current (Ifsm) of 10.6 kA. The operational temperature range spans from -40°C to +150°C.

Feature Summary

• High current handling capability with 270 A continuous forward current rating
• Robust thermal performance supporting operation up to 150°C junction temperature
• Durable construction using hard-soldered joints for high reliability
• Isolated mounting design via metal base plate

Applications

• Line rectifiers for transistorized AC motor controllers
• AC/DC motor control systems
• Industrial power supply units
• Professional light dimming equipment

Procurement Notes

Verify the specific manufacturer source when sourcing this component, as distribution channels vary. Confirm that the received unit matches the MDD255-16N1 designation exactly. Check for physical integrity of the Y1-CU package and ensure no damage to the terminal pins. Validate datasheet compliance regarding the 1600 V and 270 A ratings before integration into critical circuits.

Selection Notes

Select this module when high current capacity and robust thermal management are required in a single-phase or bridge configuration. The 1600 V rating provides sufficient margin for standard industrial line voltages. Consider the panel mount style for easy integration into existing chassis designs. Ensure the cooling solution supports the thermal dissipation requirements at full load conditions.

Part Context

This component belongs to the MDD255 series of high-current diode modules manufactured by IXYS. The series is engineered for heavy-duty power conversion tasks. Similar models in the lineup may offer different current ratings or voltage specifications while maintaining comparable packaging and mounting characteristics for system consistency.

Replacement Considerations

Direct substitutes within the same series include the MDD255-22N1 for higher voltage applications. For lower current requirements, the MDD220-16N1 is available but is noted as discontinued. Verify pin compatibility and thermal resistance values when considering alternative part numbers.
