DZ23C11-E3-18

Overview

The DZ23C11-E3-18 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 11 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 0.1 µA at 8.5 V. Dynamic resistance is specified at 20 Ω, with a temperature coefficient ranging from 5 to 9 x 10⁻⁴/°C. It supports power dissipation up to 500 mW and functions within a temperature range of -55 °C to +150 °C.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Complies with RoHS standards for commercial grade applications
• Offers high ESD protection capability exceeding 8 kV via human body model

Applications

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

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Vishay documentation. Confirm that the ordering suffix matches the required reel quantity and packaging specifications. Ensure compliance with environmental directives before finalizing procurement orders.

Selection Notes

Select this component when a 11 V reference is needed in a compact SOT-23 footprint. Evaluate thermal constraints carefully, as power dissipation drops significantly above ambient temperatures. Verify that the ±5 % tolerance aligns with circuit requirements without necessitating external trimming.

Part Context

This device belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V, providing standardized options for various design needs while maintaining consistent physical dimensions and electrical characteristics across the family.

Replacement Considerations

Direct substitutes include other DZ23 series variants with identical pinouts but different voltage ratings, such as DZ23C10 or DZ23C12. Cross-brand replacements must match the SOT-23 package, 11 V nominal voltage, and similar dynamic resistance values.
