JANTX1N5304UR-1/TR

Current Regulation - Diodes, Transistors Overview

The JANTX1N5304UR-1/TR is a current regulator diode manufactured by Microchip Technology. It operates in the surface-mount DO-213AB (MELF) package with a round-end configuration. The device provides a regulated current of 1.98 mA and supports a maximum peak operating voltage of 100 V. It dissipates up to 500 mW of power and functions within an extended temperature range from -55 °C to +175 °C. This component is qualified under MIL-PRF-19500/463 standards for military applications.

Current Regulation - Diodes, Transistors Feature Summary

• Provides stable current regulation over a broad voltage range
• Qualified for high-reliability military environments
• Utilizes a compact MELF glass encapsulation

Current Regulation - Diodes, Transistors Applications

• Military electronic systems requiring precise current limiting
• High-temperature circuit protection designs
• Space-grade instrumentation current stabilization

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1/TR against official Microchip documentation to confirm the reel packaging and round-end terminal style. Ensure the order specifies the JANTX quality level, as this denotes enhanced testing beyond standard JAN grades. Confirm RoHS status directly with the manufacturer, as military parts often carry exemptions.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current source is required in a space-constrained surface-mount layout. Compare the 1.98 mA rating against circuit load requirements to ensure adequate headroom. Verify that the 100 V breakdown voltage exceeds the maximum potential drop across the regulator in the intended application environment.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5304 series of current regulator diodes, which are axial or MELF equivalents to Zener diodes but regulate current instead of voltage. The JANTX designation indicates it meets rigorous military screening requirements. The UR-1 suffix typically denotes the specific MELF package variant with rounded ends for improved soldering reliability.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct replacements must match the 1.98 mA nominal current and 100 V maximum voltage. Equivalent military-qualified MELF packages from other vendors require verification of dynamic impedance and temperature coefficient specifications to ensure functional compatibility.
