1N5391-E3/54

Overview

The Vishay 1N5391-E3/54 is a general-purpose plastic rectifier diode featuring a glass-passivated junction and molded epoxy body in the DO-41 (DO-204AL) package. It provides a maximum average forward rectified current of 1.5 A and a maximum repetitive peak reverse voltage of 50 V. The device supports a peak forward surge current of 50 A, with a typical thermal resistance from junction to ambient of 55 °C/W. Operating temperatures range from -50 °C to +150 °C.

Feature Summary

• Glass-passivated junction for high reliability
• 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 ordering suffix /54 corresponds to the specified delivery mode of 13-inch diameter paper tape and reel. Confirm RoHS compliance status associated with the E3 suffix. Ensure lead length requirements are met for specific thermal resistance ratings during PCB mounting.

Selection Notes

Select this component when a 50 V blocking voltage rating is required alongside a 1.5 A continuous current capacity. Consider the DO-41 through-hole package for standard assembly processes. Evaluate the 150 °C junction temperature limit against the application's thermal environment.

Part Context

This part belongs to the Vishay 1N5391 through 1N5399 series of general-purpose plastic rectifiers. The series shares identical electrical characteristics except for the maximum repetitive peak reverse voltage, which varies across the lineup. The 1N5391 variant specifically defines the lower end of the voltage range within this family.

Replacement Considerations

Direct substitutes include other Vishay parts within the same 1N539x series offering different voltage ratings, such as 1N5392 or 1N5393, provided the circuit voltage requirements align.
