Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1/TR against official Microchip documentation to confirm the tape and reel packaging configuration. Ensure the MIL-PRF-19500/463 qualification level matches project requirements. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability before procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed 1.98 mA regulation is required in a compact surface-mount form factor. The wide operating temperature range supports harsh environment deployments. Verify that the 100 V peak voltage rating exceeds the maximum potential drop across the load in the target application design.

Current Regulation - Diodes, Transistors Part Context

This part is part of the 1N53xx series of current regulator diodes produced under military specifications. It shares functional similarities with other MELF-regulated diodes but is distinguished by its specific 1.98 mA output and high-temperature capability. The JANTXV prefix indicates a specific quality and screening level within the Microchip portfolio.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes must match the 1.98 mA regulation current, 100 V max voltage, and DO-213AB package. Verify pinout compatibility and thermal characteristics. Alternative parts from other manufacturers may require re-evaluation of the circuit biasing conditions.
