Overview
The AZ23B39-HE3_A-08 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 two independent Zener elements. The nominal Zener voltage is 39 V with a tight tolerance of ±2%. Electrical characteristics include a maximum dynamic resistance (ZZ) of 87 Ω at a test current of 2 mA and a reverse leakage current of 50 μA maximum at 29 V. The device is AEC-Q101 qualified for automotive applications and operates within a junction temperature range of -55 °C to +150 °C.
Feature Summary
- Dual common-anode Zener array configuration
- AEC-Q101 qualified for automotive reliability
- High ESD protection capability exceeding 8 kV HBM
- RoHS-compliant HE3_A lead-free termination
Applications
- Automotive circuit voltage regulation
- ESD protection networks
- Reference voltage generation
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm that the ordering suffix matches the required tape-and-reel packaging format and AEC-Q101 qualification status. Ensure storage conditions comply with moisture sensitivity level 1 requirements prior to soldering.
Selection Notes
Select this variant when a precise 39 V reference with ±2% tolerance is required in space-constrained designs. The common-anode topology simplifies biasing compared to single-diode solutions. Verify thermal dissipation limits against the specific PCB footprint to ensure operation remains within the 150 °C junction temperature rating.
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 standardized voltages from 2.2 V to 75 V across various tolerance grades and packaging options.
