DZ23C3V3-G3-18

Overview

The DZ23C3V3-G3-18 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 package. It features a nominal Zener voltage of 3.3 V with a tolerance of ±5 %. The device operates at a test current (IZT) of 5 mA and exhibits a dynamic resistance (ZZ) of 95 Ω at this current. Reverse leakage current is limited to 5 μA at a reverse voltage (VR) of 1 V. The component supports a maximum power dissipation of 500 mW and withstands junction temperatures up to 150 °C. It is supplied in tape-and-reel format with 10,000 units per reel.

Feature Summary

• Silicon planar construction for reliable voltage regulation
• Graded Zener voltages according to international E24 standard
• Green commercial grade material composition

Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Protection against overvoltage transients in signal lines
• Biasing networks in small-signal electronic applications

Procurement Notes

Verify the specific ordering code DZ23C3V3-G3-18 matches the required 10,000-unit reel quantity and SOT-23 packaging. Confirm compliance with RoHS directives and material categorization standards via official Vishay documentation before finalizing supply agreements. Ensure storage conditions adhere to moisture sensitivity level 1 requirements.

Selection Notes

Select this component when a precise 3.3 V reference is needed in space-constrained designs utilizing the SOT-23 footprint. Consider the 5 mA test current requirement for circuit biasing design. Evaluate thermal management needs as power dissipation drops significantly above ambient temperatures exceeding 25 °C. Verify that the ±5 % tolerance aligns with system accuracy specifications.

Part Context

This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series offers a wide range of Zener voltages from 2.2 V to 75 V, all available in the compact SOT-23 package. The G3 suffix indicates green, commercial grade construction compliant with environmental standards.

Replacement Considerations

Direct substitutes within the same family include other DZ23-G variants with different Zener voltages if voltage levels differ. Cross-brand replacements require matching SOT-23 pinout, Zener voltage tolerance, and power dissipation ratings. Verify equivalent dynamic resistance and leakage current characteristics for critical precision applications.
