CD1005-Z2V4

Overview

The CD1005-Z2V4 is a surface mount Zener diode from the Bourns CD0603/1005-Z series, designed for voltage reference applications in compact chip packages. It features a nominal Zener voltage of 2.4 V with a tolerance range of 2.28 V to 2.52 V at a test current of 5 mA. The device operates within a temperature range of -55°C to +125°C and offers low reverse leakage current of 1 µA maximum. Packaged in a leadless 1005 (2512 metric) format with gold-plated terminals, it supports standard pick-and-place manufacturing processes.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability requirements. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to assembly. Review datasheet revisions for any parameter updates that may affect design integration.

Selection Notes

Select this component when a stable 2.4 V reference is required in space-constrained designs. The 1005 package size offers significant footprint reduction compared to traditional axial leads. Verify thermal dissipation capabilities against peak forward surge current ratings during transient events. Ensure circuit impedance matches the specified test current for accurate voltage regulation.

Part Context

This part belongs to the Bourns CD0603/1005-Z Surface Mount Zener Diode Series, which provides silicon diodes with minimal packaging overhead. The series includes various Zener voltages ranging from 2.0 V to 39 V in both 0603 and 1005 formats. These components are engineered to meet JEDEC standards and facilitate automated assembly on standard surface-mount equipment.

Replacement Considerations

Direct substitutes include other parts from the same CD0603/1005-Z series with identical voltage ratings, such as CD0603-Z2V4. Cross-manufacturer replacements must match the 1005 package dimensions, 2.4 V nominal voltage, and thermal characteristics. Verify terminal plating compatibility and reverse leakage specifications before implementation.
