CDLL4762

Single Zener Diodes Overview

The CDLL4762 is a single Zener diode manufactured by Microchip Technology, designed for surface-mount applications in the DO-213AB (MELF) package. It features a nominal Zener voltage of 82 V with a tolerance of ±10%. The device operates within a temperature range of -65°C to +175°C and is rated for a power dissipation of 500 mW. Key electrical characteristics include a maximum reverse leakage current of 100 nA at 76 V and a Zener impedance of 350 ohms. This component serves as a voltage regulator or reference element in electronic circuits requiring stable DC voltage levels.

Single Zener Diodes Procurement Notes

Verify the specific suffix and tolerance requirements against the design specification before ordering. Confirm that the DO-213AB package dimensions align with the PCB footprint. Ensure the operating voltage does not exceed the maximum ratings defined in the official datasheet. Check for RoHS compliance status if required by the manufacturing process. Validate availability through authorized distributors to ensure genuine components.

Single Zener Diodes Selection Notes

Select this component when a precise 82 V reference is needed in a small form factor. Consider the ±10% tolerance for budgeting voltage variations in the circuit design. Evaluate the thermal management requirements given the 500 mW power dissipation limit. Compare the leakage current specifications against sensitive input stages. Ensure the MELF package compatibility matches the existing assembly capabilities.

Single Zener Diodes Part Context

This part belongs to the CDLL47 series of axial-equivalent surface-mount Zener diodes produced by Microchip Technology. These devices are engineered to replace traditional through-hole components while maintaining similar electrical performance profiles. The series offers various voltage options within the same physical package, simplifying inventory management for manufacturers designing high-density printed circuit boards.

Single Zener Diodes Replacement Considerations

Direct substitutes may include other 82 V Zener diodes in the DO-213AB package from different manufacturers, provided they meet the 500 mW power rating and ±10% tolerance requirements. Verify pinout compatibility and thermal characteristics before substitution.
