1N5398

Overview

The 1N5398 is a standard recovery rectifier diode manufactured by Diotec Semiconductor. It features an 800 V maximum repetitive reverse voltage and a 1.5 A average forward rectified current. The device utilizes a DO-15 through-hole package with axial leads. Key electrical characteristics include a maximum forward voltage of 1.3 V at rated current, a peak non-repetitive surge current capability of 50 A, and a low reverse leakage current of 5 uA. The junction temperature range spans from -50 °C to +175 °C, ensuring reliable operation in high-temperature environments.

Feature Summary

• High thermal stability with a maximum junction temperature rating of 175 °C
• Robust surge handling capability for transient load protection
• Low reverse leakage current for improved efficiency
• Void-free molded plastic construction for mechanical durability

Applications

• General purpose rectification in power supplies
• Free wheeling diode applications in inductive circuits
• Polarity protection in electronic systems

Procurement Notes

Verify the specific manufacturer suffix or packaging variant when ordering, as Diotec may offer different reel or tape configurations. Confirm RoHS compliance status directly with the supplier, as historical data indicates potential variations in environmental certification across production batches. Ensure the DO-15 package dimensions match your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component for designs requiring high voltage blocking up to 800 V with moderate current handling. It is suitable for general-purpose applications where standard recovery speed is sufficient. Consider the DO-15 package size for through-hole mounting constraints. Evaluate thermal management needs given the 175 °C junction limit and 1.5 A continuous current rating.

Part Context

This part belongs to the 1N4/1N5 series of plastic silicon rectifiers produced by Diotec Semiconductor. The series covers a wide range of reverse voltage ratings from 50 V to 1000 V while maintaining a consistent 1.5 A forward current capability. These components are designed for general-purpose use in various industrial and consumer electronics applications.

Replacement Considerations

Cross-reference with Vishay 1N5398GP/91 or generic 1N5398 equivalents from other manufacturers like LRC or Bilin. Verify that substitute parts meet the same 800 V reverse voltage and 1.5 A forward current specifications. Ensure the replacement maintains the DO-15 package form factor for direct board compatibility.
