1N5398-T

Overview

The Diodes Incorporated 1N5398-T is a discontinued standard recovery rectifier diode designed for general-purpose applications. It features an 800V peak repetitive reverse voltage and supports a 1.5A average rectified output current. The component utilizes a DO-15 through-hole package with molded plastic construction. Key electrical characteristics include a maximum forward voltage drop of 1.1V at rated current, a peak reverse leakage current of 5μA at 25°C, and a surge overload rating capable of handling 50A non-repetitive peak forward surge current.

Feature Summary

• Fast switching capability optimized for high efficiency
• Low forward voltage drop to minimize power loss
• Low reverse leakage current for improved performance
• Robust surge overload rating supporting high transient currents

Applications

• General purpose rectification in power supplies
• High efficiency switching circuits
• Free wheeling diode applications

Procurement Notes

This component has been officially discontinued by the manufacturer as of August 6, 2009. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturing channels. Buyers must confirm the specific packaging configuration, such as tape and reel options, when sourcing from distributors. Ensure that any replacement components meet the original electrical specifications and mechanical dimensions required for the intended circuit design.

Selection Notes

Select this component only if legacy compatibility is strictly required due to its discontinued status. Verify that the 800V reverse voltage rating aligns with the peak inverse voltage present in the application circuit. Consider the thermal resistance values when designing heat dissipation strategies, particularly for capacitive loads which require current derating. Confirm that the DO-15 package dimensions fit the available board space and mounting constraints.

Part Context

The 1N5398-T belongs to the 1N5391/S through 1N5399/S series of 1.5A rectifiers manufactured by Diodes Incorporated. This series offers various voltage ratings ranging from 50V to 1000V within the same physical footprint. The 'T' suffix specifically denotes the DO-15 package variant supplied in tape and reel format. These devices are silicon-based rectifiers intended for robust industrial and commercial electronics.
