Overview
The AZ23C10-HE3-08 is a silicon planar Zener diode from the Vishay AZ23 series, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 10 V with a standard tolerance of ±5%. The device operates as a dual common-anode configuration and is qualified to AEC-Q101 standards for automotive applications. Electrical characteristics include a maximum reverse leakage current of 0.1 µA at 8.5 V and a dynamic resistance of 7.5 Ω at a test current of 5 mA. The component supports a junction temperature up to 150 °C and complies with RoHS directives.
Feature Summary
- AEC-Q101 qualified for automotive reliability requirements
- ESD protection capability exceeding 8 kV via human body model
- RoHS-compliant HE3_A variant construction
Applications
- Automotive electronic circuit voltage regulation
- General-purpose voltage reference circuits
- Protection against overvoltage transients in low-power systems
Procurement Notes
Verify the specific ordering suffix to confirm the tape-and-reel quantity and packaging format. Confirm that the HE3_A designation aligns with required automotive qualification standards. Ensure the ±5% tolerance meets the design specifications before finalizing procurement orders.
Selection Notes
Select this component when a 10 V reference with ±5% accuracy is required in a compact SOT-23 footprint. Consider the HE3_A suffix if AEC-Q101 compliance is mandatory for the target application environment. Verify thermal dissipation limits relative to the expected ambient operating conditions.
Part Context
This part belongs to the AZ23 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 'C' indicates the standard ±5% tolerance grade, while the 'HE3' suffix denotes the specific RoHS-compliant, automotive-qualified manufacturing line.

FAQ
What is the ESD protection rating for this component?
The device provides ESD protection according to AEC-Q101 standards, supporting greater than 8 kV via the human body model and greater than 800 V via the machine model.
How does the HE3_A suffix differ from the base E3 suffix?
The HE3_A suffix indicates that the device is AEC-Q101 qualified for automotive applications, whereas the base E3 suffix typically denotes commercial grade without this specific automotive qualification.
