1N5391GP-TP

Overview

The 1N5391GP-TP is a standard recovery rectifier manufactured by Micro Commercial Components (MCC). It features a 1.5 A average forward current rating and a maximum repetitive peak reverse voltage of 50 V. The device utilizes a DO-15 axial leaded package with a plastic encapsulation rated UL 94 V-0. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 50 A, a typical reverse leakage current of 5 µA at 50 V, and a maximum forward voltage drop of 1.4 V at 1.5 A. The junction temperature range spans from -55°C to 150°C.

Feature Summary

• Glass-passivated junction structure for high reliability applications
• Low forward voltage drop for improved efficiency
• Low leakage current capability
• High forward surge current handling

Applications

• General purpose rectification
• Free wheeling diode circuits
• Power supply input stages

Procurement Notes

Verify the component status before integration, as this part may be marked as Not Recommended for New Designs (NRND) in certain distributor databases. Confirm RoHS compliance requirements against specific project standards. Ensure the ordering suffix matches the desired packaging format, such as reel or cut tape, as availability varies by supplier. Cross-reference the datasheet revision date to ensure alignment with current manufacturing specifications.

Selection Notes

Select this component when a 50 V blocking voltage and 1.5 A continuous current are required in an axial through-hole configuration. The glass-passivated construction offers superior stability compared to epoxy encapsulated alternatives. Consider the thermal management capabilities provided by the DO-15 package for heat dissipation in dense circuit layouts. Evaluate the standard recovery speed suitability for the target switching frequency.

Part Context

This device belongs to the 1N5391 series of rectifiers produced by MCC. It shares the same form factor and electrical baseline as other variants within the 1N539x family, differentiated primarily by their reverse voltage ratings. The GP suffix indicates a glass-passivated junction, while TP denotes the specific product line designation used by Micro Commercial Components for this component class.

Replacement Considerations

Direct substitutes include Vishay 1N5391GP-E3/54 and generic 1N5391 equivalents. Verify pinout compatibility and package dimensions when swapping manufacturers. Ensure the replacement maintains the same voltage and current ratings to prevent circuit failure.
