DZ23C5V1-HE3_A-08

Overview

The DZ23C5V1-HE3_A-08 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 package. It features a nominal Zener voltage of 5.1 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and provides a maximum reverse leakage current of 1 µA at 2 V. Dynamic resistance is specified at 60 Ω (max) at 2 mA and 480 Ω (max) at 1 mA. It is AEC-Q101 qualified for automotive applications, supports a junction temperature up to 150 °C, and offers ESD protection exceeding 8 kV via human body model.

Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• ESD capability exceeding 8 kV (HBM) and 800 V (MM)
• RoHS-compliant construction with HE3_A suffix

Applications

• Automotive electronic circuits requiring robust voltage regulation
• Protection against electrostatic discharge events
• Reference voltage generation in low-power systems

Procurement Notes

Verify that the ordering code includes the HE3_A suffix to confirm AEC-Q101 qualification status. Ensure the component matches the specific DZ23C5V1 marking code for correct voltage identification. Confirm RoHS compliance requirements align with the manufacturing specifications provided in the datasheet.

Selection Notes

Select this component when a 5.1 V reference with ±5 % tolerance is required in a compact SOT-23 footprint. Consider the dynamic resistance values at different test currents to ensure compatibility with circuit load conditions. Verify thermal management capabilities if operating near the maximum junction temperature limits.

Part Context

This part 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, all graded according to the international E24 standard. The HE3_A variant specifically denotes AEC-Q101 qualification within this lineup.

Replacement Considerations

Direct replacements must match the 5.1 V nominal voltage, ±5 % tolerance, and SOT-23-3 package. Verify that any substitute also holds AEC-Q101 qualification if automotive reliability is required. Check dynamic resistance and leakage current specifications to ensure functional equivalence.
