DZ23C8V2-G3-08

Overview

The DZ23C8V2-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 8.2 V with a standard tolerance of ±5 %. The device operates at a test current (IZT1) of 5 mA and exhibits a maximum dynamic resistance of 7 Ω at this current. Electrical characteristics include a reverse leakage current of 0.1 μA at VR = 6 V and a temperature coefficient ranging from +4 to +7 × 10⁻⁴/°C. Power dissipation is rated at 500 mW with leads clamped and 300 mW on an FR-4 board. Operating junction temperature ranges from -55 °C to +150 °C.

Feature Summary

• Dual-element common cathode configuration within a compact SOT-23 footprint
• Graded Zener voltages conforming to international E24 standards
• ESD protection capability exceeding 8 kV via human body model and 800 V via machine model

Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Clamping applications for transient voltage suppression
• General-purpose small signal rectification and switching

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Vishay documentation. Confirm RoHS compliance status and ensure the ordering suffix matches the required reel quantity and tape specifications. Validate that the specific batch meets the intended environmental operating conditions before integration into final assemblies.

Selection Notes

Select this component when a precise 8.2 V reference is needed in a space-constrained design. Ensure the circuit can accommodate the specified 5 mA test current for accurate voltage regulation. Consider the thermal resistance values if power dissipation exceeds 300 mW or if ambient temperatures approach the upper operational limit of +150 °C.

Part Context

This device belongs to the DZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V, all packaged in the standardized SOT-23 form factor. The G3 suffix indicates a green, commercial-grade product compliant with specific material categorization requirements defined by the manufacturer.

Replacement Considerations

Direct substitutes within the same series include other DZ23-G variants sharing the SOT-23 package and common cathode configuration. Verify that any replacement maintains the required Zener voltage tolerance and dynamic resistance specifications for the specific application context.
