Overview
The AZ23B5V6-HE3-18 is a silicon planar Zener diode from Vishay, housed in an SOT-23 surface-mount package. It features a nominal Zener voltage of 5.6 V with a tight tolerance of ±2%. The device operates at a test current of 5 mA and has a maximum reverse leakage current of 1 µA at 5 V. Dynamic resistance is specified at 40 Ω (max) at the test current. It is AEC-Q101 qualified for automotive applications, RoHS compliant, and supplied in tape-and-reel packaging with 10,000 units per reel.
Feature Summary
- AEC-Q101 qualified for automotive reliability requirements
- Tight ±2% Zener voltage tolerance for precision regulation
- ESD protection exceeding 8 kV via human body model
- RoHS-compliant commercial grade material categorization
Applications
- Automotive electronic circuit voltage regulation
- Precision reference voltage generation
- Over-voltage protection circuits
Procurement Notes
Verify the specific ordering code suffix to confirm the reel quantity and tape width. Confirm that the HE3_A designation aligns with required AEC-Q101 qualification standards. Ensure the component matches the intended thermal management footprint on the FR-4 board for optimal power dissipation.
Selection Notes
Select this part when a precise 5.6 V reference is needed in a compact SOT-23 form factor. The ±2% tolerance makes it suitable for tighter voltage regulation loops compared to standard ±5% variants. Verify that the 5 mA test current requirement fits within the target circuit's biasing constraints.
Part Context
This component belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor - Diodes Division. The series offers a wide range of Zener voltages from 2.2 V to 75 V in the same SOT-23 package family, allowing for design consistency across different voltage rails.
