Overview
The DZ23C10-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 10 V with a ±5 % tolerance and operates at a test current of 5 mA. The device has a maximum reverse leakage current of 0.1 µA at 7.5 V and a dynamic resistance of 15 Ω at 5 mA. It is qualified to AEC-Q101 standards for automotive applications, supports a junction temperature up to 150 °C, and provides ESD protection exceeding 8 kV via the human body model.
Feature Summary
- AEC-Q101 qualified for automotive reliability requirements
- Silicon planar construction with graded Zener voltages per E24 standard
- High electrostatic discharge robustness exceeding 8 kV (HBM) and 800 V (MM)
- RoHS-compliant material categorization
Applications
- Voltage reference circuits in automotive electronics
- ESD protection components in signal lines
- Clamping applications in general-purpose semiconductor designs
Procurement Notes
Verify that the ordering suffix matches HE3_A-08 to confirm AEC-Q101 qualification. Ensure the component is sourced from authorized distributors to guarantee authenticity. Cross-reference the datasheet revision against the manufacturing date code to validate compliance with the latest electrical specifications and RoHS standards before finalizing procurement orders.
Selection Notes
Select this component when a 10 V reference with ±5 % tolerance is required in an SOT-23 footprint. Confirm that the operating environment does not exceed the 150 °C junction temperature limit. Verify that the 5 mA test current aligns with the target circuit design. Consider the 15 Ω dynamic resistance for precision requirements in low-current applications.
Part Context
This part belongs to the DZ23 series of small-signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V. The HE3_A suffix specifically denotes the AEC-Q101 qualified variant, distinguishing it from the commercial grade E3 versions within the same physical package and electrical family.
Replacement Considerations
Direct replacements must match the 10 V nominal voltage, SOT-23 package, and AEC-Q101 qualification. Verify that alternative manufacturers provide equivalent dynamic resistance and leakage current specifications to ensure circuit compatibility without redesigning the bias network.
FAQ
What is the specific Zener voltage tolerance for the DZ23C10?
