Overview
The DZ23C15-HE3_A-08 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 package. It provides a nominal Zener voltage of 15 V with a tolerance of ± 5 %. The device operates at a test current of 5 mA and dissipates up to 300 mW on an FR-4 board. Key electrical parameters include a reverse leakage current of 0.05 µA maximum, dynamic resistance of 11 Ω at IZT1, and a temperature coefficient ranging from 7 to 9 x 10⁻⁴/°C. It is AEC-Q101 qualified for automotive applications.
Feature Summary
- AEC-Q101 qualified for automotive reliability
- Silicon planar construction with ESD protection exceeding 8 kV HBM
- RoHS-compliant HE3 technology
Applications
- Automotive electronic circuits requiring voltage regulation
- General-purpose voltage reference applications
- Protection against overvoltage transients in low-power systems
Procurement Notes
Verify the specific ordering code suffix matches the required reel quantity and tape width. Confirm that the HE3_A designation aligns with project requirements for AEC-Q101 qualification. Ensure the component meets RoHS compliance standards for the target market. Cross-reference the datasheet revision date with manufacturing lot codes to ensure material consistency.
Selection Notes
Select this component when a precise 15 V reference is needed in a compact SOT-23 footprint. Consider the 5 % tolerance and temperature coefficient for circuit stability. Verify power dissipation limits based on ambient temperature and PCB thermal design. Compare dynamic resistance values against signal integrity requirements.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide range of voltages from 2.2 V to 75 V. The HE3_A variant specifically denotes AEC-Q101 qualification and RoHS compliance, distinguishing it from commercial grade versions.
Replacement Considerations
Direct replacements within the same series include other DZ23C15 variants with different packaging or qualification levels. Cross-manufacturer equivalents should match the 15 V nominal voltage, SOT-23 package, and ± 5 % tolerance specifications.
