Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm exact electrical tolerances and testing levels. Ensure the procurement channel is authorized to guarantee authenticity for military-grade components. Request full traceability documentation and test reports upon delivery to validate compliance with MIL-PRF-19500/463 requirements.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a stable microampere-level current source is required in harsh environments. The DO-213AB package suits automated surface-mount assembly processes. Verify that the 429 µA regulation current aligns with the target circuit design and that the 100 V breakdown voltage exceeds the maximum expected reverse bias conditions.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the JAN series of current regulator diodes produced by Microchip's Microsemi division. These devices are engineered for high-reliability applications where standard commercial parts may fail due to extreme temperatures or radiation exposure. The 'TXV' designation indicates a specific military screening level distinct from other variants in the family.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include JANTX1N5288UR-1 and JAN1N5288UR-1, which share identical electrical characteristics but differ in military screening levels. Cross-reference with JANTXV1N5289UR-1 if a slightly higher current rating is acceptable.
