MDD26-16N1B

Overview

The IXYS MDD26-16N1B is a general-purpose silicon diode module belonging to the MDD26 series. It features a peak repetitive reverse voltage (Vrrm) of 1600 V and a maximum continuous forward current (If) of 26 A. The device utilizes a TO-240AA package with screw mount installation. Key electrical parameters include a maximum forward voltage (Vf) of 1.6 V, a peak reverse current (Ir) of 10 mA, and a non-repetitive peak forward surge current (Ifsm) of 700 A. The operating temperature range spans from -40°C to +150°C.

Feature Summary

• High voltage capability with 1600 V reverse blocking rating for robust power handling
• Designed for panel mounting using a standard TO-240AA screw-mount configuration
• Capable of sustaining high surge currents up to 700 A for transient protection

Applications

• Industrial power supply rectification circuits
• Inverter and converter bridge configurations
• DC-DC converter output stages

Procurement Notes

Verify the specific suffix N1B against the manufacturer's latest datasheet to confirm pinout orientation and terminal specifications. Ensure the procurement documentation explicitly states the 1600 V rating, as variants within the MDD26 series exist with different voltage levels. Cross-reference the package dimensions with the official TO-240AA mechanical drawing to guarantee compatibility with existing heatsink mounting hardware.

Selection Notes

Select this component when a single-phase or bridge rectifier requires a 1600 V breakdown voltage and approximately 26 A continuous current capacity. The TO-240AA form factor is suitable for applications requiring direct chassis or heatsink attachment. Consider thermal management requirements carefully, as the 1.6 V forward voltage drop generates significant heat at full load, necessitating adequate cooling solutions to maintain junction temperatures within the specified limits.

Part Context

This part belongs to the IXYS MDD26 series of discrete semiconductor modules. The series offers various current and voltage combinations, typically ranging from lower amperage options to higher current variants like the MDD44 or MDD72. These modules are engineered for industrial-grade reliability in medium-power conversion systems, providing a standardized footprint for designers integrating high-voltage silicon diodes into compact power assemblies.
