Overview
The IXYS MDD26-18N1B is a general-purpose silicon rectifier diode module from the MDD26 series. It features a peak repetitive reverse voltage (Vrrm) of 1800 V and a maximum continuous forward current (If) of 36 A. The device utilizes a TO-240 package with three pins for panel mounting. Key electrical parameters include a maximum forward voltage (Vf) of 1.5 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 1800 V reverse blocking rating
- Robust thermal performance supporting high power dissipation
- Panel mount design for secure mechanical integration
Applications
- Industrial power supply rectification
- Motor drive circuits
- Welding equipment power stages
Procurement Notes
Verify the specific suffix N1B against official datasheets to confirm pinout and thermal interface specifications. Ensure the supplier provides traceable documentation matching the manufacturer's part identification. Confirm compliance with relevant environmental standards prior to procurement.
Selection Notes
Select this component when applications require high voltage isolation combined with moderate continuous current handling. The TO-240 package facilitates direct panel mounting, simplifying heatsink integration compared to surface-mount alternatives. Evaluate thermal resistance requirements based on ambient conditions.
Part Context
This part belongs to the MDD26 series of discrete semiconductor modules manufactured by IXYS. The series offers various voltage ratings within the same physical footprint, allowing for design flexibility. These modules are designed for robust industrial environments requiring reliable power conversion.
Replacement Considerations
Cross-reference with other MDD26 series variants such as MDD26-12N1B or MDD26-16N1B if lower voltage ratings are acceptable. Verify that substitute parts maintain identical pin configurations and thermal characteristics.
