JAN1N5554US

Single Diodes Overview

The JAN1N5554US is a silicon rectifier diode manufactured by Microchip Technology. It features a maximum repetitive peak reverse voltage of 1000 V and an average forward rectified current of 3 A. The device utilizes a B-SQ-MELF-2 surface-mount package with two pins. It operates within a junction temperature range of -65°C to +175°C. The component exhibits a maximum non-repetitive peak forward surge current of 150 A and a typical forward voltage drop of 1.3 V at specified currents.

Single Diodes Feature Summary

• Hermetically sealed construction designed for high reliability in demanding environments
• Surface-mount MELF form factor suitable for automated assembly processes
• Military-grade screening and qualification per MIL-PRF-19500 standards

Single Diodes Applications

• General purpose rectification in military electronic systems
• Power supply circuits requiring high voltage isolation
• Industrial equipment operating under extreme thermal conditions

Single Diodes Procurement Notes

Verify the specific suffix US indicates the unencapsulated or specific MELF variant configuration against the official datasheet. Confirm that the procurement order explicitly references the JAN prefix to ensure compliance with military quality assurance requirements. Check for RoHS exemption status as these components often fall outside standard environmental directives due to their specialized manufacturing processes.

Single Diodes Selection Notes

Select this component when a hermetically sealed, surface-mount rectifier with 1000 V blocking capability is required. Ensure the PCB layout accommodates the B-SQ-MELF-2 package dimensions. Consider the thermal management requirements given the wide operating temperature range and the specific mounting constraints associated with MELF packages in high-reliability applications.

Single Diodes Part Context

This part belongs to the 1N555x series of general-purpose silicon rectifiers. The JAN prefix denotes a specific level of product assurance defined by MIL-PRF-19500. The US suffix typically identifies the specific physical encapsulation style, distinguishing it from axial leaded versions like the standard 1N5554.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' MIL-PRF-19500 qualified 1N5554 equivalents in MELF packages. Verify pinout compatibility and thermal resistance characteristics before substitution. Generic commercial grade 1N5554 diodes lack the hermetic sealing and rigorous screening required for this specific application.
