JANHCA1N5819

Single Diodes Overview

The JANHCA1N5819 is a Schottky barrier rectifier manufactured by Microchip Technology, designed for high-efficiency power conversion. It features a maximum repetitive peak reverse voltage of 45 V and an average forward rectified current of 1 A. The device utilizes a surface-mount DO-204AL (DO-41) package configuration. Key electrical characteristics include a maximum DC reverse leakage current of 50 µA at 45 V and a typical forward voltage drop of 490 mV at 1 A. The junction operating temperature range extends from -65°C to 150°C, ensuring reliability in demanding environments.

Single Diodes Feature Summary

• Schottky barrier technology provides low forward voltage drop and fast switching speeds.
• Military-grade qualification ensures compliance with MIL-PRF-19500/586 standards.
• Surface-mount DO-41 package facilitates automated assembly processes.

Single Diodes Applications

• High-reliability military aerospace power supplies
• Spacecraft electronic subsystems requiring radiation tolerance
• Harsh environment industrial control systems

Single Diodes Procurement Notes

Verify the specific suffix designation against the manufacturer's latest datasheet to confirm exact electrical tolerances and testing requirements. Ensure procurement channels provide valid traceability documentation for military-grade components. Confirm RoHS status as these parts may not comply with standard environmental directives due to their specialized application.

Single Diodes Selection Notes

Select this component when low forward voltage drop and high-speed switching are critical for efficiency. The surface-mount format requires compatible PCB footprint design. Consider the 45 V reverse voltage rating relative to circuit peak inverse voltages. Verify thermal management capabilities within the specified -65°C to 150°C junction temperature range for the target application.

Single Diodes Part Context

This part belongs to the JAN series of Schottky rectifiers, which are characterized by military-grade screening and reliability standards. It serves as a surface-mount alternative to through-hole variants like the JAN1N5819-1, maintaining similar electrical performance while adapting to modern assembly techniques. The DO-41 SMD package offers compact integration for space-constrained designs.

Single Diodes Replacement Considerations

Direct substitutes include JAN1N5819-1 for through-hole applications. Surface-mount equivalents from other manufacturers must match the 45 V rating, 1 A current capacity, and DO-41 footprint. Verify that any replacement meets the required military or industrial temperature specifications.
