DZ23C7V5-HE3-18

Overview

The DZ23C7V5-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 7.5 V with a standard tolerance of ±5%. The device operates within a temperature range of -55 °C to +150 °C and is AEC-Q101 qualified for automotive applications. Electrical characteristics include a maximum reverse leakage current of 0.1 µA at 6 V and a dynamic resistance of 7 Ω at a test current of 5 mA.

Feature Summary

• AEC-Q101 qualified for automotive reliability
• ESD protection exceeding 8 kV (HBM) and 800 V (MM)
• RoHS-compliant construction

Applications

• Automotive electronic circuits requiring voltage reference or regulation
• General-purpose voltage clamping and protection
• Temperature-compensated reference designs

Procurement Notes

Verify that the ordering suffix matches HE3_A-18 to confirm AEC-Q101 qualification and reel packaging. Confirm RoHS compliance status during procurement. Ensure the component meets specific automotive grade requirements before integration into final assemblies.

Selection Notes

Select this part when a 7.5 V Zener voltage with ±5% tolerance is required in an SOT-23 footprint. Consider the 7 Ω dynamic resistance and 0.1 µA leakage current for precision applications. Verify thermal management needs against the 500 mW dissipation rating at lead temperatures.

Part Context

This component belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of graded Zener voltages from 2.2 V to 75 V. The HE3 variant specifically denotes AEC-Q101 qualification and RoHS compliance, distinguishing it from commercial grade E3 versions.

Replacement Considerations

Cross-reference with other DZ23 series variants for different voltage ratings. Check equivalent parts from Diodes Incorporated such as the DZ23C7V5-7, ensuring package compatibility and electrical parameter alignment.
