Overview
The DZ23C8V2-HE3_A-08 is a silicon planar Zener diode from the Vishay DZ23 series, housed in an SOT-23 surface-mount package. It provides a nominal Zener voltage of 8.2 V with a tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum reverse leakage current of 100 nA at 6 V. Dynamic resistance is specified as 7 Ω at the test current and 50 Ω at a lower current of 1 mA. It is AEC-Q101 qualified for automotive applications and supports an operating temperature range from -55 °C to +150 °C.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- ESD protection exceeding 8 kV via human body model
- RoHS-compliant HE3_A material categorization
Applications
- Voltage reference circuits in automotive electronics
- Clamping and protection stages in signal processing
- Biasing networks requiring stable low-voltage regulation
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm that the ordering suffix matches the required tape-and-reel quantity and packaging format. Ensure compliance with RoHS directives and AEC-Q101 qualification requirements before integration into production assemblies.
Selection Notes
Select this part when a precise 8.2 V reference is needed within a compact SOT-23 footprint. Consider the dynamic resistance and leakage specifications against circuit sensitivity requirements. Verify thermal management capabilities if power dissipation approaches the 300 mW limit on standard FR-4 boards.
Part Context
This component belongs to the DZ23 series of small-signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of standardized voltages graded according to the E24 standard. The HE3_A suffix indicates AEC-Q101 qualification and specific material compliance distinct from commercial grade variants.
Replacement Considerations
Compatible substitutes include other Vishay DZ23 series parts with identical voltage ratings or equivalent Zener diodes from manufacturers offering AEC-Q101 qualified SOT-23 packages. Verify pinout compatibility and electrical parameter alignment before substitution.
FAQ
What is the marking code for the DZ23C8V2-HE3_A-08?
The marking code printed on the device is V53.
What is the typical temperature coefficient for this voltage?
The temperature coefficient ranges from 4 to 7 x 10^-4 /°C at the test current.
Is this component suitable for high-voltage surge protection?
No, it is designed for small-signal voltage regulation and clamping, not for high-energy surge protection applications.
