DZ23C4V7-G3-08

Overview

The DZ23C4V7-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 4.7 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and provides a dynamic resistance of 78 Ω. Electrical characteristics include a maximum reverse leakage current of 3 μA at 1 V and a temperature coefficient ranging from -5 to +2 × 10⁻⁴/°C. Power dissipation is rated at 500 mW on lead-mounted conditions and 300 mW on FR-4 boards, supporting an operating temperature range of -55 °C to +150 °C.

Feature Summary

• Silicon planar construction for reliable voltage regulation
• ESD protection capability exceeding 8 kV via human body model
• Green commercial grade material composition compliant with RoHS standards

Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Protection against electrostatic discharge in sensitive electronic assemblies
• General-purpose voltage clamping in consumer electronics

Procurement Notes

Verify compliance requirements before ordering, as AEC-Q101 qualification is available only upon specific request and is not standard for this part number. Confirm that the green commercial grade designation meets environmental standards for your target market. Ensure supply chain partners provide valid documentation regarding material categorization and manufacturing origin to maintain regulatory adherence.

Selection Notes

Select this component when a precise 4.7 V reference is needed within a compact SOT-23 footprint. The ±5 % tolerance suits applications where strict tight tolerances are unnecessary. Consider the thermal resistance values if designing for high ambient temperatures or limited board space. Verify that the 300 mW power rating on FR-4 substrates aligns with the expected load conditions in the final circuit design.

Part Context

This device belongs to the DZ23-G 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 components are designed for general-purpose voltage regulation tasks in modern electronic equipment requiring small form factors.

Replacement Considerations

Cross-reference with other SOT-23 Zener diodes offering 4.7 V nominal voltage and similar power ratings. Verify pinout compatibility and electrical parameter overlaps, particularly dynamic resistance and leakage current limits, before substituting.
