DZ23C11-E3-08

Overview

The DZ23C11-E3-08 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 1 V. Electrical characteristics include a dynamic resistance of 20 Ω and a temperature coefficient ranging from 5 to 9 x 10⁻⁴/°C. It supports power dissipation up to 500 mW and functions within an operating temperature range of -55 °C to +150 °C.

Feature Summary

• Silicon planar construction for reliable voltage regulation
• ESD protection capability exceeding 8 kV via human body model
• RoHS-compliant commercial grade material categorization

Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Protection against electrostatic discharge in sensitive electronics
• General-purpose clamping applications in consumer devices

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's document number 86346 and revision 1.2. Confirm that the ordering code matches the specific voltage and tolerance requirements. Ensure compliance with RoHS directives and material categorization standards before integration into production systems.

Selection Notes

Select this component when a 11 V Zener voltage with ±5 % tolerance is required in a compact SOT-23 footprint. Consider the 5 mA test current and 20 Ω dynamic resistance for circuit design accuracy. Evaluate thermal constraints based on the 500 mW power dissipation rating and ambient temperature conditions.

Part Context

This part 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, utilizing standardized E24 grading. The DZ23C11 variant specifically addresses mid-range voltage needs within this extensive portfolio of surface-mount components.

Replacement Considerations

Direct replacements within the same series include other DZ23Cxx-E3-08 variants with different voltage ratings but identical packaging and electrical configurations.
