JANTX1N5802

Single Diodes Overview

The JANTX1N5802 is a military-grade Schottky barrier rectifier manufactured by Microchip Technology. It features a maximum repetitive peak reverse voltage of 50 V and an average forward rectified current of 1 A. The device utilizes a surface-mount SQ-MELF package, designated as D-5A or A-Package-2 in various listings. Key electrical characteristics include a low forward voltage drop of approximately 875 mV at 1 A and a fast reverse recovery time of 25 ns. The component supports a wide operating junction temperature range from -65°C to +175°C and exhibits a maximum reverse leakage current of 1 µA at 50 V.

Single Diodes Feature Summary

• Schottky barrier construction for low forward voltage drop and high efficiency
• Military qualification compliant with MIL-PRF-19500 standards
• Fast reverse recovery performance suitable for high-speed switching applications
• Surface-mount SQ-MELF packaging for compact board integration

Single Diodes Applications

• High-frequency power supply rectification
• DC-DC converter output stages
• Free-wheeling diodes in inductive load circuits
• Space and defense electronic systems requiring radiation hardness

Single Diodes Procurement Notes

Verify the specific suffix (e.g., US, URS) against the design bill of materials, as package variations exist within the family. Confirm military grade certification requirements and RoHS exemption status prior to ordering. Ensure the selected variant matches the required thermal management and PCB footprint specifications for the target application.

Single Diodes Selection Notes

Select this component when low forward voltage drop and fast switching are critical for system efficiency. The military grade rating ensures reliability in extreme environmental conditions. Compare the 1 A current rating against peak load requirements to prevent thermal overload. Verify that the surface-mount package aligns with automated assembly capabilities.

Single Diodes Part Context

This part belongs to the 1N5802 series of Schottky rectifiers produced under the JAN (Military Grade) designation. The TX suffix typically indicates enhanced screening levels beyond standard military specifications. It serves as a ruggedized alternative to commercial equivalents for aerospace and defense electronics.

Single Diodes Replacement Considerations

Direct substitutes include the commercial equivalent 1N5802US for non-military applications. For identical military specifications, verify compatibility with other manufacturers' MIL-PRF-19500 qualified parts. Ensure pinout and thermal characteristics match before substitution.
