1N5399-E3/54

Overview

The Vishay General Semiconductor - Diodes Division 1N5399-E3/54 is a general-purpose plastic rectifier diode designed for standard power conversion applications. It features a DO-41 (DO-204AL) axial package with matte tin-plated leads. The device supports a maximum average forward rectified current of 1.5 A and withstands a maximum repetitive peak reverse voltage of 1000 V. Key electrical characteristics include a maximum instantaneous forward voltage of 1.4 V at 1.5 A, a typical reverse recovery time of 2.0 µs, and a maximum DC reverse current of 5.0 µA at rated blocking voltage. It offers a peak forward surge current capability of 50 A and operates within a junction temperature range of -50 to +150 °C.

Feature Summary

• Glass passivated junction construction provides high reliability and low leakage current performance.
• Molded epoxy body meets UL 94 V-0 flammability rating for enhanced safety.
• Matte tin plated leads ensure solderability per J-STD-002 standards.
• E3 suffix indicates RoHS compliance and passes JESD 201 class 1A whisker test.

Applications

• General purpose rectification in power supplies
• Inverter and converter circuits
• Freewheeling diode applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging quantity and delivery mode. The /54 suffix typically denotes tape and reel packaging, while other suffixes may indicate ammo pack or cut tape options. Confirm RoHS compliance status and material categorization definitions via the provided Vishay compliance links before finalizing procurement specifications.

Selection Notes

Select this component when a 1000 V reverse voltage rating is required alongside a 1.5 A continuous forward current capacity. Ensure the application environment remains within the specified -50 to +150 °C operating temperature range. Consider the 2.0 µs reverse recovery time for standard frequency operations and verify that the 50 A surge current capability aligns with the circuit's transient requirements.

Part Context

This part belongs to the 1N5391 through 1N5399 series of general-purpose silicon rectifiers manufactured by Vishay General Semiconductor. All members of this family share identical thermal and current ratings, differing only in their maximum repetitive peak reverse voltage ratings which range from 50 V to 1000 V. The 1N5399 represents the highest voltage variant in this specific axial package lineup.

Replacement Considerations

Direct substitutes within the same Vishay family include parts with lower voltage ratings such as 1N5398-E3/54 (800 V). Cross-manufacturer replacements must match the 1.5 A current, 1000 V voltage, and DO-41 package constraints. Verify that alternative components meet the same thermal resistance and reverse recovery time specifications.

FAQ

What is the maximum non-repetitive peak forward surge current?

The maximum non-repetitive peak forward surge current is 50 A for an 8.3 ms single half sine-wave superimposed on rated load.

Does the E3 suffix affect the electrical function of the diode?

No, the E3 suffix denotes RoHS compliance, commercial grade material categorization, and JESD 201 class 1A whisker test compliance without altering the electrical parameters.
