Overview
The AZ23B13-HE3_A-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 package. It features a nominal Zener voltage of 13 V with a tight tolerance of ±2%. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board. Key electrical parameters include a test current of 5 mA, a maximum reverse leakage current of 0.1 µA at 10 V, and a dynamic resistance of 25 Ω at 1 mA.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- AEC-Q101 qualified for automotive reliability standards
- High ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
- RoHS-compliant manufacturing process
Applications
- Automotive electronic circuits requiring AEC-Q101 compliance
- Voltage reference applications utilizing dual independent channels
- ESD protection stages in signal conditioning paths
- Power supply regulation modules operating under harsh thermal conditions
Procurement Notes
Verify component authenticity by cross-referencing the ordering code against official Vishay documentation. Confirm that the HE3_A suffix corresponds to the required AEC-Q101 qualification level. Ensure the specific ±2% tolerance variant matches the design requirements before finalizing procurement orders.
Selection Notes
Select this component when a dual-channel Zener array with high precision is required. The ±2% tolerance distinguishes it from standard ±5% variants. Verify that the 300 mW power dissipation rating aligns with the thermal management capabilities of the target PCB footprint and ambient operating environment.
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 AZ23B13-HE3_A-08 specifically represents the 13 V breakdown voltage option within the tighter tolerance subset of this family.

FAQ
What is the difference between the AZ23B13-HE3_A-08 and AZ23C13-HE3_A-08?
The primary difference is the voltage tolerance. The 'B' suffix indicates a ±2% tolerance, whereas the 'C' suffix indicates a standard ±5% tolerance. Both share the same AEC-Q101 qualification and physical package.
Does the HE3_A suffix indicate a different electrical function than the base model?
No, the HE3_A suffix denotes RoHS compliance and AEC-Q101 automotive qualification. The electrical characteristics, including Zener voltage and package type, remain identical to the commercial grade versions.
What is the maximum operating junction temperature for this device?
The maximum operating junction temperature is +150 °C, as specified in the absolute maximum ratings section of the datasheet.
