Overview
The AZ23B13-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 features a nominal Zener voltage of 13 V with a tight ±2 % tolerance. The device operates at a test current of 5 mA and provides a maximum reverse leakage current of 0.1 µA at 10 V. Dynamic resistance is specified at 25 Ω (at IZT1) and 110 x 10^-4/°C for the temperature coefficient. It supports an operating temperature range from -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board.
Feature Summary
- Dual common anode configuration within a compact SOT-23 footprint
- High precision ±2 % Zener voltage grading per E24 standard
- Extended thermal stability across -55 °C to +150 °C
- Lead-free commercial grade construction compliant with RoHS
Applications
- Precision voltage reference circuits requiring dual channels
- Overvoltage protection stages in signal conditioning paths
- Clamping applications in low-power digital logic interfaces
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer's document number 86339 and revision 1.2 against official Vishay records. Confirm that the ordering suffix G3-08 corresponds to green commercial grade packaging on an 8 mm tape reel. Ensure compliance requirements match specific project standards before finalizing acquisition.
Selection Notes
Select this variant when strict ±2 % voltage accuracy is mandatory compared to the standard ±5 % C-series options. The dual common anode topology allows independent clamping or referencing using a single shared ground node. Verify that the 300 mW power dissipation limit on FR-4 substrates accommodates the expected thermal load in the target application environment.
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 B-suffix specifically denotes the tighter 2 % tolerance band available within this standardized product family.
