APTDF500U20G

Overview

The APTDF500U20G is a single diode module manufactured by Microchip Technology, designed for high-power applications. It features a maximum repetitive peak reverse voltage of 200 V and a continuous forward current rating of 500 A. The component utilizes silicon technology and is housed in an LP4 chassis mount package. It operates within a junction temperature range from -40°C to +150°C. The device is classified as a general-purpose diode with screw mount installation style.

Feature Summary

• High current handling capability suitable for heavy-duty power conversion
• Robust chassis mount construction for efficient thermal management
• Wide operating temperature range ensuring reliability in harsh environments

Applications

• Industrial motor drives
• Power supply rectification
• Inverter circuits

Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance status according to the manufacturer's latest documentation. Confirm the LP4 package dimensions match your mechanical design constraints. Ensure the mounting hardware supports the required torque specifications for secure chassis attachment. Check for any recent product change notices that may affect pinout or electrical characteristics.

Selection Notes

Select this component when a single diode configuration with 500 A capacity is required. The 200 V rating limits its use to low-voltage high-current systems. Consider the LP4 package size for available board space. Evaluate thermal resistance requirements against your heat sink capabilities to maintain junction temperatures within the specified operational limits during peak load conditions.

Part Context

This part belongs to Microchip's discrete diode module family, specifically utilizing the LP4 casing format. It serves as a standalone rectifying element distinct from integrated bridge modules. The LP4 series is engineered for direct chassis mounting, facilitating integration into larger power electronics assemblies where high current density and thermal dissipation are critical design factors.

Replacement Considerations

Consult official substitution guides for equivalent LP4 packaged diodes with matching 500 A and 200 V ratings. Verify pin compatibility and thermal interface requirements before swapping manufacturers. Ensure alternative parts meet the same junction temperature and forward voltage specifications.
