Overview
The AZ23B11-HE3-18 is a silicon planar Zener diode array from the Vishay AZ23 series, housed in an SOT-23 surface-mount package. It features a dual common-anode configuration with a nominal Zener voltage of 11 V and 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. It is AEC-Q101 qualified for automotive reliability and offers high ESD protection exceeding 8 kV (HBM) and 800 V (MM).
Feature Summary
- AEC-Q101 qualified for automotive applications.
- Dual common-anode Zener diode array configuration.
- High electrostatic discharge (ESD) capability.
- RoHS-compliant construction.
Applications
- Automotive electronic circuits requiring voltage regulation.
- Protection against overvoltage transients.
- Reference voltage generation in precision analog systems.
Procurement Notes
Verify that the ordering code matches the specific suffix requirements for tape-and-reel packaging and AEC-Q101 qualification. 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 dual Zener array with a 11 V nominal breakdown voltage and ±2% tolerance is required. Ensure the application environment supports the specified operating temperature range and power dissipation limits on the target PCB footprint.
Part Context
This part belongs to the Vishay AZ23 series of small signal Zener diodes. The 'B' designation indicates a tighter ±2% voltage tolerance compared to the standard ±5% 'C' grade. The 'HE3_A' suffix denotes AEC-Q101 qualification and Green Molding Compound compliance.
