Overview
The AZ23B36-HE3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 surface-mount package. It features a nominal Zener voltage of 36 V with a tight tolerance of ±2%. The device operates within a junction temperature range of -55 °C to +150 °C and provides an ESD protection capability exceeding 8 kV via the human body model. It is AEC-Q101 qualified for automotive reliability and supplied in tape-and-reel packaging.
Feature Summary
- Dual common anode configuration providing two independent Zener references in a single compact package
- AEC-Q101 qualification ensuring compliance with automotive electronic component standards
- High electrostatic discharge robustness exceeding 8 kV human body model limits
- Tight voltage tolerance of ±2% for precise reference applications
Applications
- Automotive circuit voltage regulation and clamping
- Precision voltage reference generation in dual-channel systems
- Electrostatic discharge (ESD) protection for sensitive signal lines
Procurement Notes
Verify that the ordering code suffix HE3_A corresponds to the AEC-Q101 qualified automotive grade variant rather than the commercial base P/N-E3 version. Confirm the specific reel quantity matches the required production volume, as standard packaging typically involves 3000 units per reel on 7-inch carriers. Ensure the procurement documentation explicitly states the ±2% tolerance designation associated with the 'B' character in the part number.
Selection Notes
Select this component when a dual common anode topology is required to minimize board space compared to discrete single diodes. The ±2% tolerance makes it suitable for applications demanding tighter voltage accuracy than the standard ±5% graded devices. Verify that the operating environment remains within the specified -55 °C to +150 °C junction temperature range to maintain performance stability.
Part Context
This device belongs to the Vishay AZ23 series of small signal Zener diodes, which offers a wide range of voltages from 2.2 V to 75 V. The series utilizes silicon planar technology and is available in both commercial and automotive grades. The specific 'B' designation indicates the tighter ±2% voltage tolerance option, distinguishing it from the standard 'C' graded parts.

FAQ
What does the 'HE3' suffix indicate in the part number?
The 'HE3' suffix denotes that the device is RoHS-compliant and AEC-Q101 qualified for automotive applications.
How is the dual common anode configuration wired?
Pin 1 serves as the common anode connection, while Pins 2 and 3 act as the individual cathodes for the two Zener diodes.
What is the maximum power dissipation on an FR-4 board?
The maximum power dissipation is limited to 300 mW when mounted on an FR-4 board with the recommended soldering footprint.
