CD1005-Z2V2

Overview

The Bourns CD1005-Z2V2 is a surface mount Zener diode in the 1005 (2512 metric) package. It provides a nominal Zener voltage of 2.2 V with a test current of 5 mA. The device features a maximum reverse leakage current of 1 mA and a Zener impedance of 100 Ohms at the test current. Power dissipation is rated at 200 mW, and it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Compact 1005 chip package design for PCB real estate savings
• Flat configuration compatible with standard pick-and-place equipment
• Gold-plated terminals suitable for lead-free manufacturing processes

Applications

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

Procurement Notes

Verify component authenticity through authorized channels as this series is not recommended for new designs. Confirm RoHS compliance status and check for specific lot traceability requirements before procurement. Ensure storage conditions align with JEDEC standards to maintain terminal solderability and prevent moisture damage during handling.

Selection Notes

Select this component when space-constrained layouts require a 1005 footprint Zener reference. Verify that the 2.2 V breakdown voltage meets circuit requirements and that the 100 Ohm impedance is acceptable for the application's noise sensitivity. Consider the 200 mW power rating against expected thermal loads in the final assembly.
