1N4002

Single Diodes Overview

The MCC 1N4002 is a standard recovery rectifier diode housed in the DO-41 axial through-hole package. It features a maximum repetitive peak reverse voltage of 100 V and an average forward rectified current rating of 1 A. The device exhibits a typical forward voltage drop of 1.1 V at full load and maintains a low reverse leakage current of 5 µA. It supports a maximum surge current of 30 A and operates within a junction temperature range of -55 °C to +175 °C, with a reverse recovery time of 2 µs.

Single Diodes Feature Summary

• Glass-passivated junction construction for high reliability and environmental stability
• Low forward voltage drop to minimize power loss during conduction
• High forward surge current capability for transient protection
• Compliant with RoHS directives and free from hazardous substances

Single Diodes Applications

• General purpose rectification in AC/DC power supplies
• Freewheeling diodes in inductive load circuits
• Reverse polarity protection in DC input lines
• Voltage conversion stages in battery chargers

Single Diodes Procurement Notes

Verify the specific manufacturer marking on the component body to confirm Micro Commercial Components origin, as the 1N4002 designation is widely used across multiple vendors. Ensure the DO-41 package dimensions match your PCB footprint requirements. Check for RoHS compliance labels if lead-free assembly processes are mandated by your manufacturing standards.

Single Diodes Selection Notes

Select this component when a robust, general-purpose silicon rectifier is required for low-frequency applications up to 1 kHz. The 100 V reverse voltage rating provides sufficient margin for 50 V or 60 V AC systems. Consider thermal derating for continuous operation above 25 °C ambient temperature to maintain the 1 A current rating safely.

Single Diodes Part Context

This part belongs to the industry-standard 1N400x series of plastic rectifiers, where the suffix number indicates the reverse voltage breakdown level. The 1N4002 specifically denotes the 100 V variant within this family. It serves as a fundamental discrete semiconductor component for basic power electronics and signal conditioning tasks.

Single Diodes Replacement Considerations

Direct functional substitutes include Vishay 1N4002-E3/51 and Fairchild 1N4002GPT50R. Verify that replacement parts maintain the same DO-41 package outline and electrical ratings before integration into existing designs.
