DZ23C3V9-G3-08

Overview

The DZ23C3V9-G3-08 is a silicon planar Zener diode from the Vishay DZ23-G series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 3.9 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and has a maximum reverse leakage current of 3 µA at 1 V. Electrical characteristics include a dynamic resistance (ZZ) of 90 Ω at IZT1 and a temperature coefficient ranging from -7 to -3 x 10⁻⁴/°C. It supports an operating temperature range of -55 °C to +150 °C.

Feature Summary

• Dual-element common cathode configuration within a compact SOT-23 footprint
• ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
• Green commercial grade construction compliant with halogen-free material standards

Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Transient voltage suppression in signal conditioning paths
• Clamping applications for protecting sensitive semiconductor inputs

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's document number 86341 and revision 1.2 against official Vishay channels. Confirm that the ordering code matches the specific voltage grading and packaging requirements. Ensure compliance with RoHS directives and material categorization standards before finalizing acquisition.

Selection Notes

Select this component when a dual common cathode arrangement is required in a minimal surface-mount area. Evaluate the thermal impedance characteristics against the expected power dissipation limits on the target FR-4 board. Consider the negative temperature coefficient inherent to voltages below 5 V for precision circuit design.

Part Context

This part belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series provides a wide range of graded Zener voltages from 2.2 V to 75 V, all utilizing the same SOT-23 package structure. The G3 suffix indicates green, commercial-grade compliance.

Replacement Considerations

Direct substitutes within the same family include other DZ23C variants with different voltage ratings but identical pinouts and configurations. Cross-manufacturer replacements must match the SOT-23-3 footprint, 300 mW power rating, and ±5 % voltage tolerance specifications.
