DZ23C6V8-HE3-08

Overview

The DZ23C6V8-HE3-08 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 6.8 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and is AEC-Q101 qualified for automotive applications. Electrical characteristics include a maximum reverse leakage current of 2 µA at 4 V and a dynamic resistance of 8 Ω at the test current. The component supports a junction temperature up to 150 °C and offers ESD protection exceeding 8 kV via the human body model.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• High electrostatic discharge (ESD) capability exceeding 8 kV HBM
• RoHS-compliant construction with lead-free soldering compatibility

Applications

• Automotive electronic circuit protection
• Voltage reference stabilization in compact modules
• Clamping circuits in consumer electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm AEC-Q101 qualification status. Ensure that the procurement specifications align with the required tape-and-reel packaging format. Cross-reference the part number with the latest Vishay datasheet revision to validate current manufacturing availability and compliance details before finalizing orders.

Selection Notes

Select this component when a precise 6.8 V reference is required within a small SOT-23 footprint. The AEC-Q101 qualification makes it suitable for environments requiring robust performance under thermal stress. Designers should account for the specified dynamic resistance and leakage current limits to ensure accurate regulation in low-current applications.

Part Context

This device belongs to the Vishay DZ23 series of small signal Zener diodes. The series provides a wide range of graded voltages from 2.2 V to 75 V. The HE3 suffix indicates RoHS compliance and AEC-Q101 qualification, distinguishing it from the commercial grade E3 variants which lack automotive certification.

Replacement Considerations

Direct replacements within the same family include other DZ23C6V8 variants such as DZ23C6V8-E3-08, noting the difference in automotive qualification. Alternative packages or manufacturers require verification of pinout compatibility and electrical parameter matching.
