DZ23C16-E3-18

Overview

The DZ23C16-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 16 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 7 V. Dynamic resistance is specified at 40 Ω (at Izt1) and 170 Ω (at Izt2). The component supports an operating temperature range from -55 °C to +150 °C and is supplied in tape-and-reel packaging.

Feature Summary

• Silicon planar construction for reliable voltage regulation
• ESD protection exceeding 8 kV via human body model and 800 V via machine model
• RoHS-compliant commercial grade configuration

Applications

• Voltage reference circuits requiring stable low-voltage rails
• Overvoltage protection stages in signal conditioning paths
• Clamping applications in general-purpose electronic equipment

Procurement Notes

Verify that the ordering code matches the specific voltage and tolerance requirements. Confirm the suffix indicates the correct reel size and quantity. Ensure compliance with RoHS directives if required by the manufacturing process. Validate thermal management strategies against the absolute maximum ratings provided in the datasheet.

Selection Notes

Select this component when a 16 V Zener voltage is needed in a compact SOT-23 footprint. Consider the dynamic resistance and leakage current specifications for precision requirements. Evaluate the power dissipation limits relative to the expected ambient temperature and board layout 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, all graded according to the international E24 standard. These devices are designed for general-purpose voltage regulation and clamping tasks in consumer and industrial electronics.

Replacement Considerations

Direct substitutes within the same series include other DZ23 variants with different voltage ratings but identical packaging and electrical characteristics. Cross-brand replacements must match the SOT-23 footprint, 16 V nominal voltage, and ±5 % tolerance.
