1N5402

Overview

The onsemi 1N5402 is a general-purpose silicon rectifier diode housed in the DO-201AD axial leaded package. It provides an average rectified forward current of 3.0 A at 75°C and withstands a maximum repetitive reverse voltage of 200 V. The device supports a non-repetitive peak forward surge current of 200 A for a single half-sine wave lasting 8.3 ms. Electrical characteristics include a maximum forward voltage of 1.2 V at 3.0 A, a reverse current of 5.0 μA at rated voltage and 25°C, and a total capacitance of 30 pF. Operating junction temperature ranges from -55°C to +150°C.

Feature Summary

• High current capability with 3.0 A operation at 75°C without thermal runaway
• Low leakage current ensuring efficient performance under reverse bias conditions
• Robust construction supporting high forward surge currents up to 200 A

Applications

• General purpose rectification in power supplies
• Inverter circuits
• Converter applications
• Freewheeling diode implementations

Procurement Notes

Verify authenticity by purchasing directly from ON Semiconductor or authorized distributors to avoid counterfeit components. Confirm the specific part number matches the required 200 V rating within the 1N5401-1N5408 series. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Validate all operating parameters against your specific application requirements before integration.

Selection Notes

Select this component when a standard 3 A rectifier with a 200 V blocking voltage is required. Compare against other members of the 1N540x series based on specific voltage ratings: 1N5401 (100 V), 1N5404 (400 V), 1N5406 (600 V), and 1N5408 (1000 V). Ensure the DO-201AD package fits your board layout constraints. Verify that the thermal resistance and power dissipation capabilities meet your system's heat management needs.

Part Context

This device belongs to the 1N5401 through 1N5408 family of general-purpose rectifiers originally developed by Fairchild Semiconductor and now managed by ON Semiconductor. These parts share identical physical dimensions, current ratings, and thermal characteristics, differing only in their maximum repetitive reverse voltage ratings. The 1N5402 specifically fills the 200 V segment of this standardized lineup.

Replacement Considerations

Direct substitutes within the same series include 1N5401, 1N5404, 1N5406, and 1N5408, provided the voltage rating aligns with circuit requirements. Cross-manufacturer equivalents such as Vishay 1N5402-E3/66 are available but require verification of pinout compatibility and electrical parameter tolerances.
