Overview
The AZ23B7V5-E3-08 is a dual common anode Zener diode array from the Vishay AZ23 series, housed in a surface-mount SOT-23 package. It features a nominal Zener voltage of 7.5 V with a tight tolerance of ±2%. The device operates at a test current of 5 mA and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 0.1 µA at 5 V and a dynamic resistance of 7 Ω. The component supports an operating temperature range from -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- Tight ±2% voltage tolerance for precision regulation applications
- ESD protection capability exceeding 8 kV via human body model
- RoHS-compliant commercial grade silicon planar construction
Applications
- Precision voltage reference circuits requiring low tolerance
- Overvoltage protection stages in signal conditioning paths
- Clamping networks in high-speed digital interfaces
- Bias stabilization in analog sensor front-ends
Procurement Notes
Verify the specific ordering code suffix against the manufacturer's official documentation to confirm tape-and-reel specifications and minimum order quantities. Ensure that the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability of the RoHS-compliant components.
Selection Notes
Select this variant when a dual Zener array requires tighter than standard ±5% voltage accuracy. The common anode topology allows independent control of two regulated voltages from a single node. Verify that the application current does not exceed the 5 mA test condition limits to maintain specified impedance values.
Part Context
This component belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series utilizes silicon planar technology and offers a wide range of graded Zener voltages. The 'B' designation specifically indicates the ±2% tolerance tier within the product family.
