CD0603-Z5V1

Overview

The Bourns CD0603-Z5V1 is a surface mount Zener diode in a 0603 (1608 metric) package. It provides a nominal Zener voltage of 5.1 V with a tolerance range of 4.85 V to 5.36 V at a test current of 5 mA. The device features a maximum Zener impedance of 60 Ohms and a reverse leakage current of 0.1 mA. It operates within a temperature range of -55°C to +125°C and dissipates up to 150 mW of power.

Feature Summary

• Compact leadless chip design for PCB real estate savings
• Gold-plated solderable terminals conforming to MIL-STD-750 standards
• Flat configuration compatible with standard pick-and-place equipment

Applications

• DC-DC converters
• Portable electronics
• Industrial controllers
• Desktop PCs and notebooks

Procurement Notes

Verify component authenticity through authorized channels as the series is not recommended for new designs. Confirm RoHS compliance status and check for specific obsolescence notices or product change notifications prior to procurement. Ensure supply chain stability due to potential discontinuation risks associated with legacy components.

Selection Notes

Select this component when a 5.1 V reference is required in a constrained 0603 footprint. Verify that the 60 Ohm impedance and 150 mW power dissipation meet circuit requirements. Consider the operating temperature range and polarity marking for integration into existing layouts.

Part Context

This part belongs to the Bourns CD0603/1005-Z Surface Mount Zener Diode Series, designed for miniaturization in portable communications and computing equipment. The series offers various voltage options from 2.0 V to 39 V in compact chip packages smaller than many competitive parts.

Replacement Considerations

Consult official documentation for direct substitutes. Cross-referencing requires matching voltage, impedance, package size, and thermal characteristics.
