Overview
The Diotec Semiconductor 1N5394 is a standard recovery rectifier diode housed in the DO-204AC (DO-15) axial through-hole package. It features a maximum average forward rectified current of 1.5 A and a repetitive peak reverse voltage of 300 V. The device exhibits a typical forward voltage drop of 1.3 V at 1.5 A and a maximum reverse leakage current of 5 µA at 300 V. With a junction temperature range of -50°C to 175°C and a reverse recovery time of 1.5 µs, it is designed for general-purpose power supply applications.
Feature Summary
- Standard silicon rectification technology with diffused junction construction
- Low forward voltage drop for improved efficiency
- Low leakage current characteristics
- High current capability suitable for demanding loads
Applications
- General purpose rectification in power supplies
- Inverter circuits
- Converter topologies
- Freewheeling diode applications
Procurement Notes
Verify the specific manufacturer lot and RoHS compliance status upon order confirmation, as production sources may vary between Diotec and other authorized fabricators. Confirm the exact packaging format, such as cut tape or tube, matches your assembly requirements. Ensure the component meets the required environmental standards for your final product deployment before integration.
Selection Notes
Select this component when a 300 V reverse voltage rating and 1.5 A continuous current capacity are required in an axial leaded package. It serves as a direct replacement for legacy 1N5394 specifications in designs needing standard recovery times around 1.5 µs. Consider the DO-204AC footprint constraints and thermal management needs for high ambient temperatures up to 175°C.
Part Context
This part belongs to the 1N539x series of plastic rectifiers, which share identical electrical ratings but differ in reverse voltage capabilities ranging from 50 V to 1000 V. The 1N5394 specifically targets the 300 V segment within this family, offering a standardized solution for medium-voltage rectification tasks across various industrial and consumer electronics platforms.
Replacement Considerations
Public confirmed substitute part numbers include Vishay 1N5394/71 and 1N5394/73, which maintain equivalent electrical parameters and DO-41 packaging compatibility.
