1N5398GH

Overview

The 1N5398GH is a standard recovery rectifier diode manufactured by Taiwan Semiconductor Corporation. It features an 800V maximum repetitive peak reverse voltage and a 1.5A average forward rectified current rating. The device utilizes a DO-204AC (DO-15) plastic encapsulated package with axial leads for through-hole mounting. Key electrical characteristics include a low leakage current and a non-repetitive peak forward surge current capability of 50A. It is designed for general-purpose applications requiring reliable rectification in power supply circuits.

Feature Summary

• Standard recovery time for general-purpose rectification
• Low leakage current performance
• High thermal stability with extended operating temperature range
• Mechanically robust DO-15 axial leaded package

Applications

• General purpose rectification in AC to DC converters
• Free-wheeling diodes in inductive load circuits
• Power supply output stages
• Battery charging circuits

Procurement Notes

Verify the specific suffix GH against the manufacturer's latest datasheet to confirm pinout, marking codes, and compliance status. Ensure the ordering part number matches the exact package style and termination finish required for your assembly process. Cross-reference with official distributor catalogs to confirm current availability and lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when an 800V blocking voltage and 1.5A continuous current are required in a standard through-hole package. Consider the standard recovery speed suitable for line-frequency or moderate switching applications. Evaluate the thermal derating curves for high-temperature environments to ensure reliability under peak load conditions.

Part Context

This component belongs to the 1N539x series of silicon planar junction rectifiers. These devices are widely used in industrial and consumer electronics for converting alternating current to direct current. The series offers a balance of voltage rating and current handling capacity in a cost-effective axial package format.

Replacement Considerations

Direct replacements include other manufacturers' 1N5398 variants such as those from Diotec, Vishay, or onsemi. Verify that substitute parts match the 800V VRRM, 1.5A IF, and DO-15 package dimensions. Check for equivalent recovery time and leakage current specifications to ensure circuit compatibility.
