Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1 indicates the round-end variant and MELF package configuration. Confirm MIL-PRF-19500/463 compliance documentation is provided. Ensure the procurement channel supplies genuine Microchip products with traceable lot codes. Check for RoHS exemption status as military parts often contain lead.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a stable 1.76mA current source is required in a surface-mount form factor. The DO-213AB package is suitable for automated assembly processes. Consider the 100V breakdown voltage for circuit design headroom. Verify thermal management requirements given the 475mW power dissipation limit in enclosed spaces.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N530x series of current regulator diodes produced by Microchip's defense division. The JANTXV prefix denotes a specific military grade with enhanced screening. It shares functional similarities with other 1N530x variants but differs in regulated current values and package options like through-hole DO-7.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include JAN1N5303-1 for through-hole applications or other 1N5303 variants from qualified manufacturers. Verify pinout compatibility and electrical parameter tolerances before substitution. Cross-reference MIL-PRF-19500/463 equivalents for strict military compliance needs.
