Overview
The AZ23B2V7-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 two independent Zener elements. The nominal Zener voltage is 2.7 V with a tight tolerance of ±2%. Electrical characteristics include a test current of 5 mA, a maximum reverse leakage current of 20 µA at 1 V, and a dynamic resistance of 83 Ω at 1 mA. The device operates within a temperature range of -55 °C to +150 °C and supports peak soldering temperatures up to 260 °C.
Feature Summary
- Dual common-anode Zener array structure for compact circuit design
- High precision voltage regulation with ±2% tolerance
- Automotive-grade qualification compliant with AEC-Q101 standards
- Robust electrostatic discharge protection exceeding 8 kV (HBM)
Applications
- Voltage reference circuits requiring precise low-voltage regulation
- Overvoltage protection stages in automotive electronic modules
- Clamping applications in signal conditioning interfaces
Procurement Notes
Verify that the ordering code suffix matches the required tape-and-reel quantity and packaging specifications. Confirm RoHS compliance status and ensure the component meets specific environmental requirements for the intended assembly process. Cross-reference the manufacturer part number against official distribution channels to guarantee authenticity and traceability.
Selection Notes
Select this variant when a strict ±2% voltage tolerance is mandatory compared to standard ±5% options. Ensure the application accounts for the negative temperature coefficient inherent to low-voltage Zener diodes below 5 V. Verify that the power dissipation limits align with the thermal management capabilities of the printed circuit board footprint.
Part Context
This component belongs to the AZ23 series of small-signal Zener diodes manufactured by Vishay General Semiconductor. The series offers a wide range of standardized voltages from 2.2 V to 75 V in the SOT-23 package. The HE3 suffix indicates a specific lead-free formulation optimized for enhanced solderability and reliability in surface-mount applications.
