DZ23C3V6-HE3_A-08

Overview

The DZ23C3V6-HE3_A-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 3.6 V with a ±5% tolerance and operates at a test current of 5 mA. The device has a maximum reverse leakage current of 5 µA and a dynamic resistance of 90 Ω at IZT1. It is AEC-Q101 qualified for automotive applications, offering ESD protection exceeding 8 kV (HBM) and 800 V (MM). Power dissipation reaches 500 mW on leads and 300 mW on FR-4 boards, with an operating temperature range of -55 °C to +150 °C.

Feature Summary

• Dual-element common cathode configuration within a compact SOT-23 footprint
• AEC-Q101 qualification ensuring compliance with automotive reliability standards
• High electrostatic discharge robustness exceeding 8 kV human body model limits

Applications

• Automotive electronic circuits requiring AEC-Q101 compliant components
• Voltage reference and regulation in space-constrained PCB layouts
• Transient voltage suppression and clamping in sensitive signal lines

Procurement Notes

Verify component authenticity by cross-referencing the ordering code DZ23C3V6-HE3_A-08 with official Vishay documentation. Confirm that the HE3_A suffix indicates AEC-Q101 qualification rather than standard commercial grade. Ensure packaging specifications match the required reel size for automated assembly processes.

Selection Notes

Select this part when a dual Zener array is needed in an SOT-23 package with automotive qualification. Compare the 90 Ω dynamic resistance against circuit requirements for low-noise applications. Verify that the 3.6 V nominal voltage aligns with the target regulation level under the specified 5 mA test current conditions.

Part Context

This component belongs to the Vishay DZ23 series of small signal Zener diodes. The series offers various voltage grades according to the E24 standard. The specific HE3_A variant denotes RoHS compliance combined with AEC-Q101 automotive qualification, distinguishing it from the standard E3 commercial grade versions.

Replacement Considerations

Direct substitutes include other DZ23 series parts with identical electrical characteristics and AEC-Q101 qualification. Cross-manufacturer equivalents must be verified for matching pinout, thermal resistance, and package dimensions to ensure compatibility without redesigning the footprint.
