DDZX13B-7

Single Zener Diodes Overview

The DDZX13B-7 is a surface mount precision Zener diode manufactured by Diodes Incorporated, housed in an SOT23 package. It provides a nominal Zener voltage of 13V with a range of 12.55V to 13.21V at a test current of 10mA. The device features a maximum power dissipation of 300mW on an FR-4 PCB and operates within a temperature range of -65°C to +150°C. It exhibits very low leakage current (maximum 0.1µA) and tight voltage tolerance, making it suitable for automated assembly processes.

Single Zener Diodes Feature Summary

• Very sharp breakdown characteristics
• Totally lead-free and fully RoHS compliant
• Qualified to AEC-Q101 standards for high reliability
• Halogen and antimony free

Single Zener Diodes Applications

• Automotive electronic circuits
• Precision voltage reference applications
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix '-7' corresponds to the standard SOT23 tape and reel packaging containing 3,000 units per reel. Confirm that the component meets all applicable environmental compliance requirements, including RoHS and halogen-free specifications, before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 13V reference is required in a compact SOT23 footprint. Ensure the application environment supports the specified operating temperature range and that the 300mW power dissipation rating aligns with the thermal design constraints of the target PCB layout.

Single Zener Diodes Part Context

This part belongs to the DDZX5V1B through DDZX43 series of surface mount precision Zener diodes from Diodes Incorporated. The series offers various voltage options in the same SOT23 case, facilitating standardized inventory management for designs requiring different reference voltages while maintaining consistent mechanical and electrical characteristics.

Single Zener Diodes Replacement Considerations

Direct substitutes include other DDZX13B variants such as DDZX13B-13, which shares identical electrical characteristics but utilizes a 10,000-unit tape and reel packaging format. Verify pinout compatibility and thermal resistance parameters when considering alternative manufacturers.
