Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific manufacturer lineage, as production rights for this series have transitioned between MACOM and Microsemi/Microchip. Confirm that the JANTX suffix aligns with the required MIL-PRF-19500/463 qualification level for your design. Ensure the MELF-2 package orientation matches your PCB footprint requirements before finalizing procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a precise 3.96 mA regulation is required within the specified voltage limits. Compare against adjacent series values like the JANTX1N5309UR-1 or JANTX1N5311UR-1 if slight current adjustments are permissible. Verify thermal derating requirements, as the 0.5 W rating applies at +50°C and requires reduction at higher ambient temperatures.

Current Regulation - Diodes, Transistors Part Context

This part belongs to a long-standing series of 0.5 watt current regulators ranging from 0.22 mA to 10 mA. The UR-1 designation typically indicates the specific MELF-2 package variant. These devices are widely used in military and aerospace applications due to their ruggedized construction and compliance with stringent military performance standards.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include other JANTX qualified parts from the same series, such as the JANTX1N5309UR-1 or JANTX1N5311UR-1, provided the current tolerance meets system specifications. Cross-manufacturer equivalents may exist but require verification of the metallurgical bond and radiation hardness characteristics.
