Overview
The AZ23C39-HE3_A-08 is a silicon planar Zener diode array from the AZ23 series, manufactured by Vishay General Semiconductor - Diodes Division. It features a common anode configuration with two diodes integrated in a single SOT-23 package. The nominal Zener voltage is 39 V with a tolerance of ±5%. Electrical characteristics include a test current (IZT1) of 2 mA, a maximum reverse leakage current of 50 µA at 29 V, and a dynamic resistance (ZZK) of 300 Ω at IZT2. The device is AEC-Q101 qualified for automotive applications, operates within a temperature range of -55 °C to +150 °C, and has a power dissipation rating of 300 mW on an FR-4 board.
Feature Summary
- Dual-channel common anode Zener diode array in a compact surface-mount SOT-23 package
- Automotive-grade qualification compliant with AEC-Q101 standards
- ESD protection capability exceeding 8 kV via human body model and 800 V via machine model
- RoHS-compliant construction utilizing the HE3_A lead-free termination system
Applications
- Voltage reference circuits requiring dual independent channels
- Overvoltage protection for low-voltage signal lines
- Clamping applications in automotive electronic control units
- Biasing networks in precision analog measurement systems
Procurement Notes
Verify component authenticity through authorized distribution channels or direct manufacturer engagement. Confirm that the specific ordering suffix matches the required tape-and-reel packaging format and quantity specifications. Ensure compliance with RoHS3 directives and material categorization requirements prior to integration into production workflows.
Selection Notes
Select this variant when a common anode dual-diode topology is required for space-constrained designs. The ±5% voltage tolerance suits general-purpose regulation tasks where tighter precision is unnecessary. Verify thermal management capabilities against the specified junction-to-lead thermal resistance to ensure reliable operation under continuous load conditions.
Part Context
This component belongs to the AZ23 series of small-signal Zener diodes offered by Vishay Semiconductors. The series provides a wide range of standard E24 Zener voltages from 2.2 V to 75 V. The AZ23C39-HE3_A-08 specifically denotes the 39 V version with automotive qualification and standard reel packaging.
