Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix UR-1 against official Microchip documentation to confirm package style and qualification level. Ensure the procurement channel provides traceability to MIL-PRF-19500/463 standards. Confirm RoHS status as non-compliant due to military specification requirements. Validate lot traceability and test reports for critical aerospace or defense deployments.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current source is required independent of supply voltage fluctuations. Compare the 1.1 mA regulation value against circuit load requirements. Consider the 100 V maximum voltage limit for headroom. Evaluate the DO-7 package dimensions for PCB layout constraints. Verify thermal management needs given the 475 mW power dissipation capability.

Current Regulation - Diodes, Transistors Part Context

This part is part of the 1N5283-1 through 1N5314-1 series of 0.5 W current regulator diodes. It serves as a functional counterpart to Zener diodes, regulating current rather than voltage. The series offers various current values from 0.22 mA to 4.7 mA. The JANTXV designation indicates a specific quality tier within the military qualification spectrum.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include other parts from the 1N5283-1 thru 1N5314-1 series with matching current ratings. Verify equivalent MIL-PRF-19500/463 qualification levels. Check package compatibility for DO-7 axial leads. Ensure replacement devices meet the same -65°C to +175°C operating temperature range.
