Overview
The Vishay AZ23B2V2-G3-18 is a silicon planar Zener diode array housed in an SOT-23 package. It features two common-anode Zener diodes with a nominal voltage of 2.2 V and a tight tolerance of ±2%. The device operates at a test current of 5 mA, with a maximum reverse leakage current of 100 µA and a dynamic resistance of 120 Ω. It supports a junction temperature up to 150 °C and complies with RoHS standards.
Feature Summary
- Dual common-anode configuration for space-efficient circuit designs
- High ESD protection capability exceeding 8 kV (HBM) and 800 V (MM)
- Tight voltage tolerance of ±2% for precision regulation
Applications
- Voltage reference circuits requiring dual channels
- ESD protection for sensitive signal lines
- Clamping applications in low-voltage digital interfaces
Procurement Notes
Verify the specific suffix -18 indicates 10,000 units per reel when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure storage conditions adhere to moisture sensitivity level 1 requirements to maintain component integrity during assembly.
Selection Notes
Select this part for applications needing dual Zener functions in a minimal footprint. The ±2% tolerance suits precision tasks better than standard ±5% variants. Verify that the 2.2 V breakdown aligns with system voltage limits and that the 300 mW power dissipation on FR-4 boards meets thermal constraints.
Part Context
This component belongs to the AZ23-G series of small signal Zener diodes from Vishay Semiconductors. The series offers various voltage grades based on the E24 standard. The 'B' designation specifically denotes the tighter ±2% tolerance band compared to the standard 'C' grade.
Replacement Considerations
AZ23C2V2-G3-18 (±5% tolerance variant).
