Overview
The AZ23B2V7-G3-18 is a silicon planar Zener diode array from the Vishay AZ23-G series, housed in an SOT-23 surface-mount package. It features a dual common anode configuration with a nominal Zener voltage of 2.7 V and a tight tolerance of ±2%. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 20 μA at 1 V and a dynamic resistance of 83 Ω at a test current of 5 mA.
Feature Summary
- Dual common anode configuration for integrated circuit protection
- High ESD capability exceeding 8 kV (HBM) and 800 V (MM)
- Green commercial grade material categorization
Applications
- ESD protection for high-speed data lines
- Voltage reference circuits requiring low voltage stability
- Clamping applications in portable electronic devices
Procurement Notes
Verify the specific ordering code suffix against the manufacturer's documentation to confirm reel size and tape specifications. Confirm RoHS compliance status and material categorization details directly with authorized distributors or the manufacturer before finalizing procurement orders.
Selection Notes
Select this component when a precise 2.7 V clamping voltage with ±2% tolerance is required in a compact SOT-23 footprint. Ensure the application accounts for the 300 mW power dissipation limit on standard FR-4 substrates and verify that the 83 Ω dynamic resistance meets the signal integrity requirements.
