Overview
The AZ23B18-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 two independent Zener diodes sharing a common anode terminal. The nominal Zener voltage is 18 V with a tight tolerance of ±2%. Electrical characteristics are defined at a test current of 5 mA, featuring a maximum reverse leakage current of 0.05 µA and a dynamic impedance of 45 Ω. 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 configuration for space-efficient circuit design
- Tight voltage tolerance of ±2% for precision regulation applications
- High ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
- Green commercial grade construction compliant with RoHS standards
Applications
- Precision voltage reference circuits requiring dual channels
- Overvoltage protection stages in signal conditioning paths
- Clamping networks for sensitive input interfaces
Procurement Notes
Verify the specific ordering suffix against project requirements before procurement. Confirm that the tape and reel packaging dimensions match automated assembly equipment specifications. Ensure compliance with moisture sensitivity level classifications during storage and handling procedures.
Selection Notes
Select this component when a dual Zener array with high voltage accuracy is required in a compact footprint. The ±2% tolerance distinguishes it from standard ±5% variants. Verify thermal management capabilities against the absolute maximum ratings for power dissipation on FR-4 substrates.
Part Context
This part belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay General Semiconductor. The series offers a wide range of graded voltages from 2.2 V to 75 V. The 'B' designation indicates the tighter ±2% tolerance variant compared to the standard 'C' series.
