Overview
The DZ23C6V8-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 6.8 V with a standard tolerance of ±5 %. The device operates with a test current of 5 mA and includes dual common cathode configuration within the single package. It is AEC-Q101 qualified for automotive applications and complies with RoHS standards.
Feature Summary
- AEC-Q101 qualified for automotive reliability requirements
- ESD protection capability exceeding 8 kV via human body model
- Dual common cathode configuration in a compact SOT-23 footprint
Applications
- Automotive electronic circuits requiring robust ESD protection
- Voltage reference and regulation in space-constrained designs
- Clamping and protection stages in signal processing paths
Procurement Notes
Verify that the ordering suffix matches the required tape and reel specifications. Confirm the HE3_A designation indicates AEC-Q101 qualification rather than commercial grade. Ensure the specific voltage code corresponds to the intended circuit requirements before finalizing procurement orders.
Selection Notes
Select this component when a dual common cathode arrangement is needed in a minimal footprint. The AEC-Q101 qualification makes it suitable for automotive environments. Verify thermal management capabilities against the specified power dissipation limits under expected operating conditions.
Part Context
This part belongs to the DZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage options graded according to the E24 standard. The HE3_A variant specifically denotes RoHS compliance combined with automotive qualification standards.
Replacement Considerations
Direct substitutes include other DZ23 series parts with identical packaging and qualification, such as DZ23C6V8-E3-08, though the latter lacks AEC-Q101 certification. Cross-manufacturer replacements must match the SOT-23 package dimensions and electrical characteristics precisely.
