Overview
The AZ23B3V6-HE3_A-18 is a silicon planar Zener diode from the AZ23 series, manufactured by Vishay Semiconductors. It features a dual common anode configuration within a SOT-23 package. The nominal Zener voltage is 3.6 V with a tight tolerance of ±2%. Electrical characteristics include a test current of 5 mA, a maximum reverse leakage current of 1 µA at 1 V, and a dynamic resistance of 90 Ω at 1 kHz. The device is AEC-Q101 qualified for automotive applications and operates within a temperature range of -55 °C to +150 °C.
Feature Summary
- Dual common anode circuit configuration
- AEC-Q101 qualification for automotive reliability
- High ESD protection capability exceeding 8 kV HBM
Applications
- Automotive electronic circuits requiring robust voltage regulation
- ESD protection in sensitive signal lines
- Reference voltage generation in low-power systems
Procurement Notes
Verify that the ordering code matches the specific suffix requirements for automotive grade (HE3_A) and reel size (-18). Confirm RoHS compliance status and material categorization details directly with the manufacturer or authorized distributors before finalizing procurement orders.
Selection Notes
Select this component when a precise 3.6 V reference with ±2% tolerance is required in a compact SOT-23 footprint. Ensure the application environment meets the specified operating temperature range and consider the dual common anode topology for circuit design integration.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes. The series offers a wide Zener voltage range from 2.2 V to 75 V. Variants are available with different tolerances and packaging options to suit various commercial and industrial needs.
Replacement Considerations
Direct substitutes within the same series include AZ23B3V6-E3-18 for commercial grade or AZ23B3V6-HE3_A-08 for automotive grade on smaller reels. Cross-brand replacements must match the SOT-23 package, 3.6 V nominal voltage, ±2% tolerance, and dual common anode configuration.
FAQ
What is the difference between the HE3_A and E3 suffixes?
The HE3_A suffix indicates the device is AEC-Q101 qualified for automotive applications, whereas the E3 suffix denotes a commercial grade product.
What does the 'B' indicate in the part number AZ23B3V6?
The 'B' indicates a Zener voltage tolerance of ±2%, compared to 'C' which indicates ±5% tolerance.
What is the ESD rating for this component?
The device has an ESD capability of greater than 8 kV according to the Human Body Model (HBM) and greater than 800 V according to the Machine Model (MM).
