DZ23C5V6-HE3_A-18

Overview

The DZ23C5V6-HE3_A-18 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 5.6 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 1 μA at 4 V. Dynamic resistance is specified at 40 Ω (at IZT1) and 400 Ω (at IZT2). It is AEC-Q101 qualified for automotive applications, supports a power dissipation of up to 500 mW, and functions within a temperature range of -55 °C to +150 °C.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• ESD protection capability exceeding 8 kV via human body model
• RoHS-compliant construction with halogen-free materials

Applications

• Automotive voltage regulation circuits
• General-purpose voltage reference applications
• Protection against electrostatic discharge events

Procurement Notes

Verify that the ordering suffix matches the required tape-and-reel specifications. Confirm the HE3_A designation aligns with specific automotive qualification requirements. Ensure the component meets RoHS compliance standards for the target manufacturing environment. Validate the package type against PCB footprint constraints before finalizing procurement orders.

Selection Notes

Select this component when a 5.6 V reference with ±5 % tolerance is required in an SOT-23 form factor. Consider the 5 mA test current and 40 Ω dynamic resistance for precision circuit design. Verify thermal management capabilities if operating near the upper limits of the junction temperature range.

Part Context

This part belongs to the Vishay DZ23 series of small signal Zener diodes. The series covers a wide voltage range from 2.2 V to 75 V. The HE3_A suffix indicates AEC-Q101 qualification and RoHS compliance, distinguishing it from commercial grade variants.

Replacement Considerations

Direct replacements must match the 5.6 V nominal voltage, SOT-23 package, and AEC-Q101 qualification. Verify equivalent dynamic resistance and leakage current specifications to ensure circuit compatibility.
