Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix 'B' against the official Microchip datasheet to confirm exact electrical tolerances and package variations, as suffixes often denote specific manufacturing lot or quality grades. Confirm RoHS compliance status directly from the manufacturer's documentation before procurement, as historical data indicates potential non-compliance for similar variants.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed 0.3 mA current source is required in a minimal footprint. Ensure the application voltage does not exceed the 1 V limit. Compare against standard Zener diodes if voltage reference functionality is also needed, as this part is optimized strictly for current regulation rather than voltage clamping.

Current Regulation - Diodes, Transistors Part Context

This component belongs to the family of discrete current regulator diodes produced by Microchip Technology (formerly Microsemi). These devices are typically used where simple, cost-effective current control is necessary without the complexity of active transistor-based regulators. The CD5286 variant serves as the base model for this specific 0.3 mA specification.

Current Regulation - Diodes, Transistors Replacement Considerations

Publicly confirmed substitute part numbers for the CD5286B are not available in the provided documentation. Verify compatibility with generic 0.3 mA current regulator diodes only after confirming pinout and voltage specifications match the original design requirements.
