1N5401/54

Overview

The Vishay General Semiconductor 1N5401/54 is a general-purpose plastic rectifier diode belonging to the 1N5400 through 1N5408 series. It features a DO-201AD molded epoxy package with axial leads and provides a maximum average forward rectified current of 3.0 A at an ambient temperature of 25 °C. The device supports a maximum repetitive peak reverse voltage (VRRM) of 100 V, with a corresponding maximum RMS voltage of 70 V and DC blocking voltage of 100 V. Peak forward surge current capability reaches 200 A for an 8.3 ms single half sine-wave. Electrical characteristics include a maximum instantaneous forward voltage of 1.2 V at 3.0 A and a maximum DC reverse current of 5.0 μA at rated voltage and 25 °C. Operating junction and storage temperatures range from -50 °C to +150 °C.

Feature Summary

• Low forward voltage drop
• Low leakage current
• High forward surge capability

Applications

• General purpose rectification of power supplies
• Inverter circuits
• Converter applications
• Freewheeling diodes

Procurement Notes

Verify that the specific ordering suffix matches the required delivery mode, as the /54 designation indicates paper tape and reel packaging. Confirm RoHS compliance status by checking for the E3 suffix in the base part number. Ensure the procurement specification aligns with commercial grade requirements, as these devices are not qualified for automotive standards.

Selection Notes

Select this component for standard rectification tasks requiring high surge tolerance and low leakage. Verify thermal management needs against the typical thermal resistance of 20 °C/W. Consider derating the forward current if operating lead temperatures exceed 105 °C or if using shorter lead lengths than specified. Validate suitability for the target application environment, noting the absence of automotive qualification.

Part Context

This component is part of the Vishay 1N5400 thru 1N5408 series of general-purpose silicon rectifiers. The series covers reverse voltage ratings from 50 V to 1000 V while maintaining a consistent 3.0 A average forward current rating across all variants. The 1N5401 specifically denotes the 100 V breakdown variant within this standardized lineup.

Replacement Considerations

Cross-reference with other manufacturers' 1N5401 equivalents. Verify pinout orientation and package dimensions match DO-201AD specifications. Check electrical parameters such as forward voltage and reverse leakage current to ensure compatibility with the original circuit design.
