1N5402G

Overview

The 1N5402G is a standard silicon rectifier diode manufactured by SMC Diode Solutions. It features a maximum average forward rectified current of 3A and a peak repetitive reverse voltage of 200V. The device utilizes a DO-201AD axial through-hole package with a molded epoxy body rated UL-94V-0. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 200A, a typical forward voltage drop of 1.2V at full load, and a low reverse leakage current of 5µA at the rated voltage. The junction temperature range spans from -65°C to 150°C.

Feature Summary

• High forward surge capability for handling transient overloads
• Low leakage current ensuring efficient operation under reverse bias
• Molded epoxy body providing mechanical robustness and flammability compliance

Applications

• General purpose rectification in power supplies
• Inverter circuits
• Converter topologies

Procurement Notes

Verify the specific manufacturer designation when sourcing, as multiple vendors produce this component. Confirm that the ordering suffix matches the required lead-free and halogen-free specifications. Ensure the package type corresponds to the DO-201AD axial form factor. Cross-reference datasheets to confirm exact electrical tolerances match the design requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring reliable general-purpose rectification at moderate voltages. The 200V rating suits lower voltage AC-to-DC conversion stages. Consider the thermal management capabilities provided by the DO-201AD package for heat dissipation. Evaluate the 3A continuous current limit against the circuit's peak load demands to ensure adequate safety margins during operation.

Part Context

This part belongs to the widely recognized 1N540x series of plastic rectifiers. It shares the same physical footprint and basic performance profile as other members of the family, differentiated primarily by their reverse voltage ratings. The 1N5402G specifically targets the 200V segment within this lineup, offering a standardized solution for industrial and consumer electronics manufacturing.

Replacement Considerations

Compatible substitutes include Vishay 1N5402-E3/66 and equivalent parts from other manufacturers adhering to the 1N5402 specification.
