Overview
The CD1005-Z2 is a surface-mount Zener diode from the CD0603/1005-Z series, manufactured by Bourns Inc. It utilizes a 1005 (2512 metric) molded plastic package with gold-plated terminals. The nominal Zener voltage is 2.0 V, with a minimum of 1.90 V and a maximum of 2.1 V at a test current of 5 mA. Key electrical parameters include a maximum Zener impedance of 100 Ohms, a reverse leakage current of 100 µA, and a power dissipation rating of 0.5 W at 25°C. The device operates within a temperature range of -55°C to +125°C.
Feature Summary
- Compact 1005 surface mount footprint designed for PCB real estate savings in portable electronics.
- RoHS compliant construction with gold-plated solderable terminals conforming to MIL-STD-750 standards.
- Flat configuration minimizes roll-away during standard pick-and-place assembly processes.
Applications
- DC-DC converters
- Portable electronics
- Industrial controllers
- Desktop PCs and notebooks
Procurement Notes
Verify the specific suffix code against the official Bourns datasheet to confirm the exact Zener voltage tolerance and marking code. Confirm RoHS compliance status as required by project specifications. Ensure the ordering part number matches the desired package size and voltage rating precisely before procurement.
Selection Notes
Select this component for applications requiring a low-voltage reference or protection in space-constrained designs. Evaluate the thermal derating curve if operating temperatures exceed 25°C. Verify that the dynamic impedance and leakage current specifications meet the circuit requirements for the intended operating conditions.
Part Context
This component belongs to the CD0603/1005-Z Surface Mount Zener Diode Series. It shares common characteristics with other variants in the series, such as the CD0603-Z2, differing primarily in physical package dimensions. The series offers a wide range of Zener voltages from 2.0 V to 39 V across both 0603 and 1005 form factors.
Replacement Considerations
Public confirmed substitute part numbers are not provided in the source material. Cross-reference with other manufacturers offering 1005 package Zener diodes with similar voltage and impedance specifications if substitution is necessary.
