DZ23C11-G3-18

Overview

The DZ23C11-G3-18 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 11 V with a standard tolerance of ±5 %. The device operates within a test current range of 2 to 5 mA and dissipates up to 500 mW at ambient conditions, or 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 0.1 μA at 8.5 V, a dynamic resistance (ZZ) of 20 Ω at IZT1, and a temperature coefficient ranging from 5 to 9 × 10⁻⁴/°C. It supports an operating temperature range from -55 °C to +150 °C.

Feature Summary

• Silicon planar construction providing robust ESD protection exceeding 8 kV via human body model and 800 V via machine model.
• Dual configuration available as common cathode within the broader DZ23-G family for space-constrained designs.
• Green commercial grade material categorization compliant with international standards.

Applications

• Voltage reference circuits requiring stable potential levels.
• Overvoltage protection stages in signal processing paths.
• Clamping applications in low-power electronic assemblies.

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm availability and compliance status. Ensure that the ordering suffix matches the required tape and reel specifications for automated assembly processes. Cross-reference technical parameters with application requirements before finalizing procurement decisions.

Selection Notes

Select this component based on the required Zener voltage tolerance and power dissipation limits. Consider the thermal resistance values when designing heat dissipation strategies for high-density PCB layouts. Verify compatibility with the intended operating temperature range and ensure the package footprint aligns with the design constraints.

Part Context

This component belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of Zener voltages graded according to the E24 standard. The DZ23C11 variant specifically targets applications needing precise voltage regulation in compact surface-mount environments.

Replacement Considerations

Direct substitutes within the same series include other DZ23Cxx-G3-18 variants with different Zener voltages. For equivalent performance, verify matching electrical characteristics such as dynamic resistance and leakage current. Consult official replacement guides for cross-referencing with similar packages from other manufacturers.
