DZ23C7V5-E3-18

Overview

The DZ23C7V5-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 7.5 V with a standard tolerance of ±5 %. The device operates within a junction temperature range of -55 °C to +150 °C and supports a maximum power dissipation of 500 mW at ambient conditions, or 300 mW on an FR-4 board. Electrical characteristics include a reverse leakage current of 0.1 μA maximum at 7 V and a dynamic resistance of 7 Ω at a test current of 5 mA.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Features ESD protection capability exceeding 8 kV via human body model
• Complies with RoHS standards for commercial grade applications

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in low-power electronics
• Clamping applications in signal processing paths

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against official Vishay documentation. Confirm that the ordering suffix matches the required reel quantity and tape specifications. Ensure compliance with environmental directives relevant to the target deployment region before finalizing acquisition.

Selection Notes

Select this component when a 7.5 V reference is needed in a compact SOT-23 footprint. Evaluate thermal constraints carefully, as power dissipation drops significantly when mounted on FR-4 substrates compared to lead-clamped conditions. Verify that the ±5 % tolerance aligns with circuit requirements.

Part Context

This device 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, offering standardized grading according to international E24 standards. The specific part represents a common voltage point within this extensive portfolio.

Replacement Considerations

Direct substitutes within the same series include other DZ23 variants sharing the SOT-23 package and electrical profile. Cross-reference datasheet parameters such as dynamic resistance and leakage current to ensure functional equivalence in existing designs.
