JANTXV1N5308UR-1/TR

Overview

The JANTXV1N5308UR-1/TR is a silicon current regulator diode manufactured by Microchip Technology. It operates in the DO-213AB (MELF) surface-mount package and provides a nominal regulation current of 2.7 mA with a maximum limiting voltage of 2.15 V. The device complies with MIL-PRF-19500/463 specifications for JANTXV grade, ensuring suitability for military applications. It features a single-element configuration with an isolated case connection and utilizes field-effect technology.

Feature Summary

• High source impedance for stable current regulation
• Internal metallurgical bond construction
• JANTXV qualification per MIL-PRF-19500/463

Applications

• Military electronic systems requiring precise current control
• Circuits needing constant current sources over broad voltage ranges
• Protection circuits utilizing regulated current sinks

Procurement Notes

Verify that the ordering suffix /TR indicates tape-and-reel packaging when sourcing from distributors. Confirm the JANTXV grade designation matches specific reliability requirements. Ensure the MELF package type aligns with available surface-mount assembly equipment. Cross-reference the manufacturer part number against official Microchip documentation to confirm active status and compliance with the referenced performance specification sheet.

Selection Notes

Select this component when a 2.7 mA regulation current is required in a hermetic or sealed surface-mount environment. The JANTXV grade offers enhanced screening compared to standard JAN levels. Consider the 2.15 V limiting voltage to ensure compatibility with downstream circuit biasing. Verify thermal management capabilities within the DO-213AB package constraints for the intended operating temperature range.

Part Context

This part belongs to the 1N5308 series of current regulator diodes, which are standardized under MIL-PRF-19500/463. The series includes variants ranging from 0.22 mA to 10 mA. The UR-1 suffix typically denotes the MELF package form factor. Microchip Technology produces these devices to meet Department of Defense acquisition requirements for semiconductor reliability.

Replacement Considerations

Compatible substitutes include JANTX1N5308UR-1 and JANS1N5308UR-1, which share identical electrical characteristics but differ in qualification grade. Standard commercial equivalents like 1N5308UR-1 may lack the required military screening. Verify pinout and package dimensions before substitution.
