DZ23C9V1-HE3-08

Overview

The DZ23C9V1-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 9.1 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 7 V. It is AEC-Q101 qualified for automotive applications and offers ESD protection exceeding 8 kV (HBM) and 800 V (MM). Power dissipation is rated at 500 mW on FR-4 boards, with an operating temperature range of -55 °C to +150 °C.

Feature Summary

• AEC-Q101 qualified for automotive reliability requirements
• High electrostatic discharge capability per AEC-Q101 standards
• RoHS-compliant construction with lead-free soldering compatibility

Applications

• Automotive electronic circuitry requiring robust voltage regulation
• General-purpose voltage reference applications
• Protection circuits utilizing high ESD tolerance

Procurement Notes

Verify that the ordering code includes the HE3 suffix to confirm AEC-Q101 qualification status. Ensure the reel size matches the required tape width (8 mm or 13 mm) as specified in the ordering information table. Cross-reference the specific voltage grading against the E24 standard list provided in the datasheet to ensure correct part selection.

Selection Notes

Select this component when a 9.1 V reference is needed in a compact SOT-23 footprint. Confirm that the 5 mA test current aligns with the target circuit design. Verify thermal management capabilities if ambient temperatures approach the upper limit of 150 °C, considering the derating curve provided in the typical characteristics section.

Part Context

This device belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V. The HE3 variant specifically denotes RoHS compliance and automotive qualification, distinguishing it from the commercial grade E3 versions within the same physical package family.

Replacement Considerations

Direct substitutes include other DZ23C9V1 variants such as DZ23C9V1-E3-08 (commercial grade) or DZ23C9V1-G3-08. Ensure any replacement maintains the SOT-23 package dimensions and meets the required AEC-Q101 qualification if automotive use is intended.
