Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific JAN suffix qualification against MIL-PRF-19500/463 requirements before procurement. Confirm that the DO-213AB-2 footprint matches the design layout. Ensure the tape and reel packaging aligns with automated assembly equipment specifications. Validate the 616 uA current tolerance meets circuit precision needs.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a precise, low-current regulation value is required in a compact surface-mount form factor. Compare the 616 uA specification against other variants in the 1N5283-1 through 1N5314-1 series if different current levels are needed. Ensure the 100 V breakdown voltage exceeds the maximum circuit potential to prevent device failure during operation.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators. These devices serve as counterparts to Zener diodes by regulating current rather than voltage. The series offers various current values in standard tolerances within axial-leaded or SMT packages, providing versatile solutions for constant current applications.

Current Regulation - Diodes, Transistors Replacement Considerations

Check for JAN1N5291UR-1 without the /TR suffix if bulk packaging is acceptable. Verify compatibility with other manufacturers' equivalents offering identical 616 uA regulation and DO-213AB-2 dimensions.
