CD1005-Z10

Overview

The Bourns CD1005-Z10 is a surface mount Zener diode in the 1005 (2512) package, offering a nominal voltage of 10 V with a range of 9.50 V to 10.50 V. It features a maximum Zener impedance of 15 Ohms at 5 mA and a reverse current of 7.5 mA. The device 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 molded plastic case for PCB real estate savings
• Gold plated terminals solderable per MIL-STD-750 Method 2026
• Flat configuration minimizes roll-away on standard pick and place equipment

Applications

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

Procurement Notes

Verify the specific suffix code matches the required Zener voltage tolerance and impedance specifications from the official datasheet table. Confirm RoHS compliance status as per directive 2002/95/EC and recast 2011/65/EU. Ensure the component is suitable for the intended thermal environment given the 0.2 W power dissipation limit at 25°C ambient temperature.

Selection Notes

Select this component when space constraints require a 1005 footprint instead of larger packages. Verify that the 15 Ohm dynamic impedance meets circuit stability requirements. Consider the -55°C to +125°C operating range for environmental suitability. Note that this series is not recommended for new designs according to manufacturer guidance.
