1N5399S-T

Overview

The Diodes Incorporated 1N5399S-T is a discontinued general-purpose silicon rectifier diode designed for high-efficiency applications. It features a DO-41 plastic package with tin-plated axial leads and offers a peak repetitive reverse voltage of 1000 V. The device supports an average rectified output current of 1.5 A at 70°C ambient temperature and withstands non-repetitive peak forward surge currents up to 50 A. Key electrical characteristics include a maximum forward voltage drop of 1.1 V at rated current, low reverse leakage current (5 μA at 25°C), and typical total capacitance of 20 pF. Operating temperatures range from -65°C to +150°C.

Feature Summary

• Fast switching capability optimized for high efficiency
• High current handling with low forward voltage drop
• Low reverse leakage current performance
• Surge overload rating supporting 50 A peak current

Applications

• General purpose rectification in power supplies
• High frequency switching circuits
• Industrial control systems requiring robust surge protection

Procurement Notes

This component has been officially discontinued by the manufacturer as of August 6, 2009. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturing channels. Ensure that any sourced units match the specific DO-41 package designation indicated by the 'S' suffix and confirm RoHS compliance status if required for modern assembly processes.

Selection Notes

Select this part only when legacy compatibility with the 1N5399 series specifications is required. The 'S' suffix specifically denotes the DO-41 package variant, which differs physically from the standard DO-15 version. Designers must account for the discontinuation status and verify that the 1.5 A current rating and 1000 V blocking voltage meet the circuit requirements under derating conditions.

Part Context

The 1N5399S-T belongs to the 1N5391/S through 1N5399/S family of 1.5 A rectifiers produced by Diodes Incorporated. This series provides various reverse voltage ratings from 50 V to 1000 V within the same physical footprint. The 'S' suffix distinguishes the DO-41 package form factor from the larger DO-15 case used in the non-suffixed variants, allowing for different board layout constraints while maintaining identical electrical performance profiles across the series.

Replacement Considerations

As the product is discontinued, substitute parts must be sourced from other manufacturers offering equivalent 1.5 A, 1000 V rectifiers in the DO-41 package. Verify that replacement components match the forward voltage drop and thermal resistance characteristics to ensure circuit reliability without redesign.

FAQ

What does the 'S' suffix indicate in the 1N5399S-T model number?

The 'S' suffix designates that the device is housed in a DO-41 plastic package, distinguishing it from the DO-15 package found in the standard 1N5399 model.

Is the 1N5399S-T currently in production?

No, Diodes Incorporated officially discontinued the 1N5399S-T on August 6, 2009.

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

The device can withstand a non-repetitive peak forward surge current of 50 A for an 8.3 ms single half sine-wave superimposed on rated load.
