Overview
The AZ23C5V1-G3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23-G series, housed in a SOT-23 surface-mount package. It provides a nominal Zener voltage of 5.1 V with a standard tolerance of ±5 %. The device operates at a test current of 5 mA and features a maximum dynamic resistance of 60 Ω. Electrical characteristics include a reverse leakage current of 1 μA at 4.85 V and a temperature coefficient ranging from -3 to +4 x 10⁻⁴/°C. It supports an operating temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- Graded Zener voltages conforming to international E24 standards
- ESD protection capability exceeding 8 kV via human body model
Applications
- Voltage reference circuits requiring stable low-voltage regulation
- Overvoltage protection stages in signal conditioning paths
- Clamping applications in portable electronic devices
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer's document number 86339 and revision 1.2 against official Vishay channels. Confirm that the ordering suffix G3 indicates compliance with RoHS 3 directives and defines the commercial grade material categorization. Ensure the specific tape and reel packaging matches the required quantity specifications for production integration.
Selection Notes
Select this variant when a precise 5.1 V reference is needed within a tight ±5 % tolerance band. The dual common anode structure allows independent control of two Zener elements using only three pins. Verify that the 60 Ω dynamic resistance meets the noise and stability requirements of the target application under the specified 5 mA test current conditions.
Part Context
This component belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series utilizes silicon planar technology and offers a wide range of graded voltages from 2.2 V to 75 V. The AZ23C5V1-G3-08 specifically represents the 5.1 V step within the standard 5 % tolerance subset of this family.
