DZ23C3V6-HE3-18

Overview

The DZ23C3V6-HE3-18 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 standard tolerance of ±5 %. The device operates at a test current of 5 mA and provides a maximum dynamic resistance of 90 Ω at this current. It is qualified to AEC-Q101 standards for automotive applications and offers high ESD protection capability exceeding 8 kV via the human body model. The component is RoHS compliant and designed for reliable operation across a wide temperature range.

Feature Summary

• Dual common cathode configuration within a single compact SOT-23 package
• AEC-Q101 qualification ensuring suitability for automotive electronic environments
• High electrostatic discharge robustness exceeding 8 kV (HBM) and 800 V (MM)
• RoHS-compliant manufacturing process for commercial and industrial use

Applications

• Voltage reference circuits requiring stable low-voltage regulation
• Clamping and protection stages in automotive-grade electronic modules
• General-purpose voltage regulation in compact surface-mount designs

Procurement Notes

Verify that the specific ordering suffix matches the required reel size and quantity. Confirm the presence of the HE3_A designation to ensure AEC-Q101 automotive qualification is included. Cross-reference the manufacturer's document number 86346 to access the latest electrical specifications and mechanical dimensions before finalizing procurement orders.

Selection Notes

Select this component when a precise 3.6 V reference is needed in a small footprint. Ensure the application current does not exceed the 5 mA test condition to maintain accuracy. Verify thermal management requirements against the specified junction-to-lead thermal resistance. Confirm that the ±5 % voltage tolerance aligns with the circuit design constraints.

Part Context

This part belongs to the DZ23 series of dual surface mount Zener diodes manufactured by Vishay Semiconductors. The series covers a broad voltage range from 2.2 V to 75 V. The HE3 variant specifically denotes AEC-Q101 qualification, distinguishing it from the standard commercial grade E3 versions. All variants share the same SOT-23 physical package and pinout configuration.

Replacement Considerations

Direct substitutes include other manufacturers' parts within the DZ23 family or equivalent SOT-23 Zener arrays. Ensure any replacement maintains the 3.6 V nominal voltage, ±5 % tolerance, and AEC-Q101 qualification if automotive reliability is required. Verify that the dynamic resistance and leakage current parameters meet the original design specifications.
