1N5391-TP

Overview

The MCC 1N5391-TP is a standard recovery rectifier diode rated for 50V maximum repetitive peak reverse voltage and 1.5A average forward current. It utilizes the DO-15 axial through-hole package with an isolated cathode. Key electrical characteristics include a maximum instantaneous forward voltage of 1.1V at 1.5A, a typical junction capacitance of 20pF measured at 1.0MHz, and a maximum DC reverse current of 5.0µA at 25°C. The device supports a peak forward surge current of 50A for half-sine pulses and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Low leakage current capability
• High current handling capacity
• Lead-free finish compliant with RoHS standards

Applications

• General-purpose rectification in power supplies
• AC-to-DC conversion circuits
• Battery charging systems

Procurement Notes

Verify component authenticity by purchasing exclusively from Micro Commercial Components or their authorized distributors to ensure traceability and quality compliance. Confirm that the ordering suffix matches the required packaging format, as the -TP designation specifically indicates tape and reel supply. Check for specific environmental requirements such as halogen-free availability if needed for your application constraints.

Selection Notes

Select this component when a robust axial rectifier is required for moderate voltage applications up to 50V reverse blocking. Ensure the circuit design accommodates the specified thermal resistance of 26°C/W junction-to-lead. Verify that the operating ambient temperature allows for proper derating of the 1.5A average forward current rating according to the manufacturer's curves.

Part Context

This part belongs to the 1N5391 through 1N5399 series, which shares identical physical dimensions and general electrical performance profiles while varying only in maximum repetitive peak reverse voltage ratings. The series covers a voltage range from 50V to 1000V, providing a standardized solution for various rectification needs within the same package footprint.

Replacement Considerations

Direct substitutes include other manufacturers' 1N5391 equivalents meeting DO-15 specifications. Verify that any replacement maintains the 1.5A current rating, 50V reverse voltage, and similar forward voltage drop characteristics to ensure circuit compatibility.
