DZ23C8V2-HE3-08

Overview

The DZ23C8V2-HE3-08 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 8.2 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 0.1 µA at 1 V. Electrical characteristics include a dynamic resistance (ZZ) of 7 Ω and a temperature coefficient ranging from 4 to 7 x 10⁻⁴/°C. It supports power dissipation up to 500 mW on leads and 300 mW on FR-4 boards, with an operating temperature range of -55 °C to +150 °C.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• High ESD protection capability exceeding 8 kV HBM and 800 V MM
• RoHS-compliant construction with halogen-free materials

Applications

• Voltage reference circuits requiring stable regulation
• Overvoltage protection stages in electronic systems
• Clamping applications in signal conditioning paths

Procurement Notes

Verify component authenticity by cross-referencing the ordering code DZ23C8V2-HE3-08 with official Vishay documentation. Confirm that the HE3 suffix indicates AEC-Q101 qualification and RoHS compliance as specified in the datasheet. Ensure procurement channels provide valid traceability records for automotive-grade components.

Selection Notes

Select this component when an 8.2 V regulation point is required within a compact SOT-23 footprint. Consider the specific dynamic resistance and temperature coefficient values for precision requirements. Verify that the 300 mW thermal rating on FR-4 substrates aligns with the target circuit's power dissipation constraints.

Part Context

This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of graded voltages from 2.2 V to 75 V according to the E24 standard. The HE3 variant specifically denotes automotive qualification and enhanced environmental compliance compared to commercial grades.

Replacement Considerations

Direct substitutes within the same family include other DZ23C8V2 variants such as DZ23C8V2-E3-08 or DZ23C8V2-HE3_A-08. These alternatives share identical electrical specifications but may differ in packaging quantities or specific automotive qualification status.
