DZ23C2V7-E3-08

Overview

The DZ23C2V7-E3-08 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 2.7 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 20 µA at 1 V. Dynamic resistance is specified at 83 Ω (max) at the test current. It supports a junction temperature up to 150 °C and offers ESD protection exceeding 8 kV via the human body model.

Feature Summary

• Utilizes silicon planar technology for robust voltage regulation
• Provides high electrostatic discharge immunity per AEC-Q101 standards
• Complies with RoHS directives for commercial grade applications

Applications

• Voltage reference circuits requiring low-voltage stability
• Protection against electrostatic discharge in sensitive electronics
• General-purpose voltage regulation in compact surface-mount designs

Procurement Notes

Verify that the ordering suffix -08 corresponds to the 8 mm tape on a 7-inch reel configuration. Confirm the component is the commercial grade base part number without the HE3_A suffix, as this indicates it lacks AEC-Q101 automotive qualification. Ensure the specific voltage code matches the required 2.7 V specification before finalizing orders.

Selection Notes

Select this component when a precise 2.7 V reference is needed in a small SOT-23 footprint. Note that the dynamic resistance is relatively high compared to higher voltage variants in the series. Verify that the operating environment does not require automotive-grade reliability, as this specific part number is designated for commercial use only.

Part Context

This device belongs to the Vishay DZ23 series of small signal Zener diodes. The series covers a wide range of voltages from 2.2 V to 75 V, all graded according to the international E24 standard. The DZ23C2V7 variant specifically addresses the lower end of this spectrum, offering tight tolerance regulation suitable for precision analog applications.

Replacement Considerations

Direct replacements within the same family include other DZ23C2Vx-E3-08 variants with different voltage ratings. For equivalent performance in a different package, consider SOD-323 or SOD-523 Zener diodes from Vishay or other manufacturers, ensuring matching voltage and power dissipation capabilities.
