MD36K18D1-BP

Overview

The MD36K18D1-BP is a standard recovery power diode module manufactured by Micro Commercial Components. It features a dual common cathode configuration housed in the D1 chassis mount package. The device is rated for a maximum repetitive peak reverse voltage of 1800 V and an average forward rectified current of 36 A per leg. It utilizes silicon technology with glass passivation for enhanced reliability. The module supports a junction temperature range from -40°C to +150°C, ensuring stable operation in demanding industrial environments.

Feature Summary

• Dual common cathode configuration for bridge rectifier applications
• Glass passivated silicon construction for improved durability
• Chassis mount design facilitating efficient heat dissipation

Applications

• Industrial power supply systems
• Inverter circuits
• Motor drive rectification

Procurement Notes

Verify the specific suffix BP against official MCC documentation to confirm compliance with RoHS standards and halogen-free requirements. Ensure that the D1 package dimensions match the thermal management design of the target application. Cross-reference the 1800 V rating with system voltage peaks to prevent overvoltage failure during transient conditions.

Selection Notes

Select this component when high voltage isolation and robust mechanical mounting are required. The 36 A current rating suits medium-to-high power industrial loads. Consider the thermal resistance characteristics inherent to the D1 package for heatsink sizing. Validate that the standard recovery speed meets the switching frequency requirements of the circuit topology.

Part Context

This module belongs to the MD36K series of glass passivated rectifier diodes from Micro Commercial Components. The series offers various voltage ratings including 800 V, 1200 V, and 1800 V options within the same current and package footprint. This specific part represents the highest voltage variant in the 36 A class, designed for challenging electrical environments requiring significant reverse bias tolerance.

Replacement Considerations

Compatible substitutes include MD36K16D1-BP (1600 V) and MD36K12D1-BP (1200 V) if lower voltage ratings are acceptable. For higher current needs, the MD120K16D1-BP series may be considered, though it requires different mechanical integration due to distinct package specifications.
