Overview
The AZ23B3V0-HE3-08 is a silicon planar Zener diode from the AZ23 series, manufactured by Vishay Semiconductors. It features a dual common anode configuration within an SOT-23 surface-mount package. The nominal Zener voltage is 3.0 V with a tight tolerance of ±2%. Rated for a maximum power dissipation of 500 mW and operating temperatures ranging from -55 °C to +150 °C, this component holds AEC-Q101 qualification for automotive applications.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- Dual common anode circuit configuration
- Silicon planar construction with ESD protection exceeding 8 kV (HBM)
- Tight voltage tolerance of ±2% indicated by the 'B' suffix
Applications
- Automotive electronic circuits requiring precise voltage reference
- General-purpose voltage regulation in compact designs
- Clamping and protection of sensitive signal lines
Procurement Notes
Verify the specific ordering code against current availability as manufacturing status may change. Confirm that the HE3_A suffix aligns with required AEC-Q101 automotive qualification. Ensure the ±2% tolerance meets design specifications before procurement. Check for RoHS compliance documentation if required by local regulations.
Selection Notes
Select this part when a dual common anode topology is required for space-constrained PCB layouts. The ±2% tolerance offers higher precision than standard ±5% variants. Verify that the 3.0 V nominal voltage matches the target regulation point. Consider the SOT-23 package dimensions for mechanical fitment.
Part Context
This component belongs to the AZ23 series of small signal Zener diodes. The series provides a wide range of voltages from 2.2 V to 75 V. Variants are available with different tolerances and packaging options to suit various commercial and industrial requirements.
Replacement Considerations
AZ23B3V0-E3-08: Identical electrical characteristics but without AEC-Q101 automotive qualification.
FAQ
What does the 'B' in the model number indicate?
The 'B' indicates a Zener voltage tolerance of ±2%, which is tighter than the standard ±5% tolerance found in 'C' series variants.
Is this component suitable for automotive use?
Yes, the HE3_A suffix denotes that the device is AEC-Q101 qualified for automotive applications.
What is the maximum power dissipation?
The maximum power dissipation is 500 mW, though it is rated at 300 mW on an FR-4 board with the recommended soldering footprint.
