Overview
The DZ23C6V2-HE3_A-18 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 package. It features a nominal Zener voltage of 6.2 V with a ±5% tolerance at a test current of 5 mA. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 500 mW. It holds AEC-Q101 qualification and offers high ESD protection exceeding 8 kV (HBM) and 800 V (MM). The HE3 technology ensures RoHS compliance.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- High electrostatic discharge robustness exceeding 8 kV human body model
- RoHS-compliant construction utilizing HE3 technology
Applications
- Voltage reference circuits requiring stable potential
- Overvoltage protection stages in electronic systems
- Clamping applications in signal conditioning paths
Procurement Notes
Verify the specific ordering suffix matches the required reel configuration and qualification level. Confirm that the HE3_A designation aligns with project requirements for AEC-Q101 compliance. Ensure the package type corresponds to the intended PCB footprint. Validate all electrical parameters against the latest official datasheet before finalizing procurement decisions.
Selection Notes
Select this component when a 6.2 V regulation point is needed in a compact SOT-23 form factor. Consider the thermal resistance values if operating near maximum power dissipation limits. Verify that the dynamic impedance characteristics meet the noise sensitivity requirements of the target application circuit design.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series covers a wide voltage range from 2.2 V to 75 V. The HE3 variant specifically denotes automotive-grade qualification and enhanced environmental compliance compared to standard commercial versions.
Replacement Considerations
Direct substitutes must match the 6.2 V nominal voltage, SOT-23 package, and AEC-Q101 qualification. Verify pinout compatibility and thermal characteristics before substitution.
