1N5400-E3/51

Overview

The Vishay 1N5400-E3/51 is a silicon rectifier diode in the DO-201AD axial package. It supports a maximum average forward rectified current of 3.0 A and a repetitive peak reverse voltage of 50 V. The device withstands a peak forward surge current of 200 A with a maximum instantaneous forward voltage of 1.2 V at rated current. Reverse leakage current is limited to 5.0 μA at 25 °C, rising to 500 μA at 150 °C. Operating junction and storage temperatures range from -50 °C to +150 °C.

Feature Summary

• Low forward voltage drop for efficient power conversion
• High forward surge capability for transient protection
• Low leakage current characteristics
• Matte tin plated leads compliant with JESD 201 class 1A whisker test

Applications

• General purpose rectification of power supplies
• Inverter circuits
• Converter applications
• Freewheeling diodes

Procurement Notes

Verify that the ordering suffix /51 corresponds to the specific bulk packaging configuration required for your assembly process. Confirm RoHS compliance status matches project specifications. Ensure lead length requirements align with board layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a 50 V blocking voltage is sufficient for the circuit design. The 3.0 A continuous current rating accommodates moderate load requirements. Verify thermal management needs against the 20 °C/W thermal resistance characteristic for reliable operation within the specified temperature range.

Part Context

This part belongs to the Vishay 1N5400 through 1N5408 series of general-purpose plastic rectifiers. The series shares identical mechanical dimensions and electrical ratings except for the repetitive peak reverse voltage, which varies from 50 V to 1000 V across the product line.

Replacement Considerations

Direct substitutes include other Vishay parts within the same 1N540x series featuring different voltage ratings, such as 1N5401 or 1N5402, provided the system voltage requirements are met.
