MPE-220AVR

Overview

The MPE-220A-L is a silicon Schottky barrier diode designed for high-frequency rectification applications. It features a resin molded structure with UL94V-0 flammability rating. The device supports a peak reverse voltage of 100 V and an average forward current of 20 A, subject to derating curves based on case temperature. Key electrical characteristics include a maximum forward voltage drop of 0.85 V at 10 A and a low reverse leakage current of 1.0 µA at rated voltage. Thermal resistance from junction to case is limited to 2.5 °C/W, ensuring efficient heat dissipation under operational loads.

Feature Summary

• Schottky barrier construction enables fast switching and reduced forward voltage drop for improved efficiency in high-frequency circuits.
• Robust thermal management capabilities with low junction-to-case thermal resistance suitable for demanding power environments.
• Resin molded package provides mechanical stability and meets UL94V-0 flammability standards for safety compliance.

Applications

• High frequency rectification in power supply units
• Free-wheeling diodes in DC-DC converters
• Reverse polarity protection circuits

Procurement Notes

Verify the specific ordering suffix against official Sanken Electric documentation to confirm exact packaging and marking variations. Ensure component authenticity by sourcing through authorized distributors or direct manufacturer channels. Confirm that the received parts match the specified absolute maximum ratings and electrical characteristics prior to integration into final assemblies.

Selection Notes

Select this component when designing circuits requiring low forward voltage drop and high surge current handling capability up to 120 A. Consider the thermal derating requirements carefully, as the average forward current decreases significantly as case temperature rises above ambient levels. Ensure the operating environment remains within the specified junction temperature range of -40°C to +150°C for reliable long-term performance.

Part Context

This device belongs to Sanken Electric's lineup of silicon Schottky barrier diodes engineered for robust power electronics applications. The MPE series utilizes advanced semiconductor technology to minimize conduction losses while maintaining high reliability. Designed primarily for industrial and consumer power conversion systems, it offers a compact solution for managing high currents in space-constrained PCB layouts.

Replacement Considerations

Consult official Sanken Electric substitution guides for verified equivalent part numbers. Do not assume functional compatibility with generic Schottky diodes lacking identical thermal resistance or surge current ratings. Verify pinout and package dimensions before swapping components in existing designs.
