Overview
The DZ23C3V3-HE3_A-18 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 3.3 V with a tolerance of ±5 %. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 5 μA at 1 V and a dynamic resistance of 95 Ω at a test current of 5 mA. This specific part number denotes AEC-Q101 qualification and packaging in 10,000-unit reels.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- ESD protection capability exceeding 8 kV via human body model
- RoHS-compliant construction with HE3_A suffix indicating automotive grade
Applications
- Automotive electronic circuits requiring robust ESD protection
- Voltage reference applications in space-constrained designs
- Clamping and protection stages in signal conditioning paths
Procurement Notes
Verify that the ordering code matches the required AEC-Q101 qualification and reel quantity. Confirm the package type is SOT-23 and check for RoHS compliance documentation. Ensure the supplier provides traceability data consistent with automotive component requirements before finalizing orders.
Selection Notes
Select this component when a 3.3 V reference with tight tolerance is needed in an SOT-23 footprint. Consider the 95 Ω dynamic resistance for low-current applications. Verify thermal management capabilities against the 300 mW dissipation limit on standard PCBs.
Part Context
This device belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of standardized voltages from 2.2 V to 75 V. The HE3_A suffix specifically identifies the automotive-grade variant with enhanced reliability testing compared to commercial grades.
Replacement Considerations
Direct replacements must match the 3.3 V nominal voltage, SOT-23 package, and AEC-Q101 qualification. Verify dynamic resistance and leakage current specifications to ensure circuit compatibility without redesigning bias networks.
