1N5394

Overview

The onsemi 1N5394 is a general-purpose silicon rectifier diode designed for standard power conversion applications. It features an axial leaded DO-15 plastic package and supports a maximum average forward rectified current of 1.5 A at 75°C ambient temperature. The device provides a maximum repetitive peak reverse voltage of 300 V, with a non-repetitive peak forward surge current capability of 50 A. Key electrical characteristics include a low forward voltage drop and minimal reverse leakage current, ensuring efficient operation in resistive or inductive loads.

Feature Summary

• Utilizes diffused junction technology to achieve low forward voltage drop and low leakage current.
• Constructed with a molded plastic case carrying UL recognition (94V-0 flammability rating).
• Features axial leads that are solderable per MIL-STD-202 standards.
• Capable of easy cleaning with Freon, alcohol, isopropanol, and similar solvents.

Applications

• General purpose rectification in power supplies.
• Inverter circuits.
• Converter topologies.
• Freewheeling diode implementations.

Procurement Notes

Verify the specific manufacturer source, as the 1N5394 part number is produced by multiple vendors including onsemi and Vishay. Confirm that the datasheet matches the required DO-15 package dimensions and electrical ratings. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure the component is not obsolete or restricted before finalizing procurement plans.

Selection Notes

Select this component when a through-hole silicon rectifier with 1.5 A continuous current handling is required. The 300 V reverse voltage rating suits medium-voltage AC-to-DC conversion tasks. Consider the thermal derating requirements for capacitive loads, which typically require a 20% reduction in current capacity compared to resistive or inductive loads.

Part Context

This device belongs to the 1N539x series of general-purpose plastic rectifiers. The series covers a range of reverse voltage ratings from 50 V to 1000 V while maintaining a consistent 1.5 A forward current capability. These components are widely used in industrial and consumer electronics for basic power rectification needs.

Replacement Considerations

Direct substitutes include other manufacturers' versions of the 1N5394 specification, such as those from Vishay (e.g., 1N5394/71). Verify pinout compatibility and package style (DO-15) when cross-referencing alternative sources.
