CDLL5817

Single Diodes Overview

The CDLL5817 is a silicon Schottky barrier rectifier manufactured by Microchip Technology. It features a maximum repetitive reverse voltage of 20 V and an average forward rectified current of 1 A. The device utilizes a DO-213AB (MELF) surface-mount package. Key electrical parameters include a maximum forward voltage of 600 mV at 1 A and a maximum reverse leakage current of 1 mA at 20 V. The component operates within a junction temperature range of -65°C to 125°C.

Single Diodes Feature Summary

• Schottky barrier technology for low forward voltage drop
• Surface-mount MELF package design
• High surge current capability

Single Diodes Applications

• Power supply rectification
• Free-wheeling diodes in DC-DC converters
• Polarity protection circuits

Single Diodes Procurement Notes

Verify the specific suffix (e.g., /TR for tape and reel) against the Bill of Materials, as packaging affects handling. Confirm RoHS compliance status with the supplier, as historical data indicates variations. Ensure the MELF package footprint matches the PCB layout requirements before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a surface-mount Schottky rectifier with 20 V blocking voltage and 1 A continuous current rating is required. Compare the 600 mV forward voltage specification against system efficiency targets. Verify that the DO-213AB package dimensions fit the available board space constraints.

Single Diodes Part Context

This part belongs to the Microchip CDLL581x series of small-signal Schottky rectifiers. It shares functional similarities with through-hole equivalents like the 1N5817 but offers a compact surface-mount form factor. The series is designed for general-purpose rectification applications requiring fast switching characteristics.
