JANS1N5290UR-1

Current Regulation - Diodes, Transistors Overview

The JANS1N5290UR-1 is a hermetically sealed current regulator diode manufactured by Microchip Technology. It operates in the SMD/SMT form factor within the DO-213AB-2 package. The device provides a regulated current of 517 µA with a maximum voltage rating of 100 V and a power dissipation capacity of 500 mW. Designed for military applications, it complies with MIL-PRF-19500/463 standards. The component functions as a constant current source, maintaining stable performance across an operating temperature range of -65°C to +175°C.

Current Regulation - Diodes, Transistors Feature Summary

• Hermetic sealing ensures reliability in harsh environments
• Military-grade qualification under MIL-PRF-19500/463
• Round-end surface mount construction for robust mounting

Current Regulation - Diodes, Transistors Applications

• Military aerospace electronic systems
• High-reliability current regulation circuits
• Harsh environment sensor biasing

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1 indicates the round-end SMT variant compatible with DO-213AB packages. Confirm MIL-PRF-19500/463 compliance requirements match the target system specifications. Check for RoHS exemption status as military parts often differ from commercial standards. Ensure handling procedures account for hermetic glass encapsulation integrity during assembly.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed 517 µA current source is required in a compact surface-mount format. Compare against JAN1N5290UR-1 if non-hermetic packaging suffices for the application. Consider thermal management capabilities given the 500 mW power limit. Verify that the 100 V breakdown voltage meets the circuit's maximum operating conditions.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N52xx series of current regulator diodes produced by Microchip. The JANS prefix denotes a specific military grade level within the broader family. It shares functional similarities with other 517 µA regulators but differs in packaging and environmental sealing compared to standard commercial equivalents.

Current Regulation - Diodes, Transistors Replacement Considerations

JAN1N5290UR-1 serves as a non-hermetic alternative within the same electrical specification family.
