CD1005-Z3

Overview

The CD1005-Z3 is a surface mount Zener diode from the CD0603/1005-Z series, manufactured by Bourns Inc. It utilizes a 1005 (2512) molded plastic package with gold-plated terminals. The nominal Zener voltage is 3.0 V, with a minimum of 2.85 V and a maximum of 3.15 V at an impedance test current of 5 mA. The device exhibits a maximum Zener impedance of 95 Ohms and a reverse leakage current of 1 mA. It supports a power dissipation of 0.2 W at 25°C and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Compact 1005 chip package designed for PCB real estate savings in portable electronics.
• Gold-plated terminals ensure solderability per MIL-STD-750 Method 2026.
• Flat configuration minimizes roll-away during standard pick-and-place mounting.
• Conforms to JEDEC standards for reliable handling and integration.

Applications

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

Procurement Notes

Verify the specific suffix code against the official datasheet to confirm the exact Zener voltage rating, as the series covers a wide range from 2.0 V to 39 V. Confirm RoHS compliance status if required by your manufacturing specifications. Ensure the ordering code matches the desired voltage tolerance and impedance characteristics listed in the electrical table. Cross-reference the package dimensions with your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when space-constrained designs require a surface mount Zener diode in a 1005 format. Consider the 95 Ohm maximum impedance and 1 mA reverse current limits for precision reference applications. Evaluate the thermal derating curve if operating near the upper temperature limit of 125°C. Ensure the circuit design accounts for the specified power dissipation constraints under ambient conditions.
