DZ23C10-HE3-18

Overview

The DZ23C10-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 10 V with a ±5 % tolerance and a test current of 5 mA. The device has a maximum dynamic resistance of 15 Ω at IZT1 and a reverse leakage current of 100 nA at VR = 7 V. It is AEC-Q101 qualified for automotive applications, operates within a temperature range of -55 °C to +150 °C, and dissipates up to 300 mW on an FR-4 board.

Feature Summary

• Dual-element common cathode configuration integrated into a compact SOT-23 footprint
• AEC-Q101 qualification ensuring compliance with automotive reliability standards
• ESD protection capability exceeding 8 kV via human body model and 800 V via machine model

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation before procurement. Confirm that the HE3 designation aligns with required AEC-Q101 automotive qualification standards. Ensure the -18 tape-and-reel format matches automated assembly equipment specifications. Validate RoHS compliance status through the manufacturer's latest material categorization reports.

Selection Notes

Select this component when a dual Zener array in an SOT-23 package is required for automotive-grade designs. The 10 V nominal rating suits low-voltage reference applications. Verify thermal management requirements against the 300 mW dissipation limit on standard FR-4 substrates. Consider the 15 Ω dynamic resistance for precision regulation needs.

Part Context

This part belongs to the Vishay DZ23 series of small-signal Zener diodes. The series offers graded voltages per the E24 standard. The HE3 variant specifically denotes AEC-Q101 qualification, distinguishing it from the commercial grade E3 versions. All variants share identical electrical characteristics and physical dimensions.

Replacement Considerations

Direct substitutes include other DZ23C10 variants such as DZ23C10-E3-18 or DZ23C10-G3-18. Note that non-HE3 parts lack AEC-Q101 automotive qualification. Cross-manufacturer replacements must match the SOT-23 package, 10 V nominal voltage, and 300 mW power dissipation limits.
