Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1/TR against official Microchip documentation to confirm tape-and-reel packaging configuration. Ensure the JAN TX quality level meets project requirements for radiation hardness or reliability. Cross-reference the datasheet revision date to validate parameter accuracy before integration into final designs.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a surface-mount current regulator is required for high-temperature environments. Compare the 2.42 mA nominal current against circuit load requirements. Consider the DO-213AB footprint constraints and verify that the 100 V breakdown voltage exceeds the maximum expected reverse voltage in the application.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5306 series of current regulator diodes, which are counterparts to Zener diodes but regulate current instead of voltage. The series spans currents from 0.22 mA to 4.7 mA. The JANTX designation indicates a higher reliability grade than standard JAN parts, suitable for demanding industrial or aerospace applications.

Current Regulation - Diodes, Transistors Replacement Considerations

Compatible substitutes include other manufacturers' MELF current regulators with matching 2.42 mA nominal current and DO-213AB packages. Verify electrical parameters such as dynamic impedance and leakage current to ensure functional equivalence without redesigning the surrounding circuitry.
