DZ23C2V7-HE3_A-08

Overview

The DZ23C2V7-HE3_A-08 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 2.7 V with a ±5% tolerance and operates at a test current of 5 mA. The device has a maximum reverse leakage current of 20 µA at 1 V and a dynamic resistance of 83 Ω at 5 mA. It is AEC-Q101 qualified for automotive applications, offering ESD protection exceeding 8 kV (HBM) and 800 V (MM). Power dissipation is rated at 500 mW on lead and 300 mW on an FR-4 board, with an operating temperature range of -55 °C to +150 °C.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• High electrostatic discharge (ESD) capability per human body and machine models
• RoHS-compliant construction with material categorization compliance

Applications

• Automotive electronic circuits requiring robust voltage regulation
• General-purpose voltage reference applications
• Protection against overvoltage transients in sensitive logic circuits

Procurement Notes

Verify that the ordering code includes the HE3_A suffix to confirm AEC-Q101 qualification and automotive grade status. Ensure the final two digits match '08' for the standard 8 mm tape reel packaging configuration. Cross-reference the specific datasheet revision to confirm all electrical parameters align with your design requirements before procurement.

Selection Notes

Select this component when a low-voltage Zener reference near 2.7 V is required within an automotive environment. The SOT-23 package provides space efficiency for compact designs. Consider the negative temperature coefficient inherent to Zener voltages below approximately 5 V when designing precision analog circuits or temperature-sensitive reference networks.

Part Context

This part belongs to the Vishay DZ23 series of small signal Zener diodes. The series offers a wide range of graded Zener voltages from 2.2 V to 75 V according to the E24 standard. While commercial versions exist without the HE3_A suffix, this specific variant is designated for automotive use, ensuring higher reliability and adherence to strict automotive quality standards.

Replacement Considerations

Direct replacements must maintain the 2.7 V nominal voltage, SOT-23 footprint, and AEC-Q101 qualification. Verify that alternative components meet the same power dissipation limits and ESD protection ratings to ensure functional equivalence in existing automotive circuit layouts.
