DZ23C15-E3-18

Overview

The DZ23C15-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 15 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 0.05 µA at 12 V. Dynamic resistance is specified at 30 Ω (max) at the test current, while knee impedance reaches 110 Ω (max). The component supports a power dissipation of up to 500 mW and functions within a temperature range of -55 °C to +150 °C.

Feature Summary

• Silicon planar construction for reliable voltage regulation
• Graded Zener voltages according to international E24 standards
• ESD protection capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing paths

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm reel size and minimum order quantity requirements. Confirm RoHS compliance status and material categorization details directly from the manufacturer's declaration before finalizing procurement specifications.

Selection Notes

Select this component when a 15 V regulation point is required in a compact SOT-23 footprint. Ensure the application current remains near the 5 mA test condition to maintain accuracy within the ±5 % tolerance band. Verify thermal management capabilities if operating near the upper limits of the junction temperature range.

Part Context

This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of nominal voltages from 2.2 V to 75 V, all utilizing the same SOT-23 package format. The base product line focuses on commercial grade performance with standardized electrical characteristics.

Replacement Considerations

Direct substitutes include other Vishay DZ23 variants with identical packaging but different voltage ratings, such as DZ23C16 or DZ23C13. Cross-manufacturer replacements must match the SOT-23 outline, 15 V nominal voltage, and similar dynamic resistance values.
