Overview
The AZ23B24-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 24 V with a tight tolerance of ±2%. The device operates at a test current of 5 mA and dissipates up to 300 mW on an FR-4 board. Electrical characteristics include a maximum reverse leakage current of 0.05 µA at 17 V and a dynamic resistance of 70 Ω at 5 mA. The component supports an operating temperature range from -55 °C to +150 °C.
Feature Summary
- Dual common anode configuration for space-efficient circuit design
- Tight ±2% voltage tolerance for precision regulation applications
- High ESD protection capability exceeding 8 kV via human body model
Applications
- Precision voltage reference circuits requiring low tolerance
- Over-voltage protection stages in sensitive electronics
- Clamping applications in signal conditioning paths
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 variant when a precise 24 V reference is required with strict tolerance limits. Ensure the application current does not exceed the 5 mA test condition to maintain accuracy. Verify that the thermal environment allows for the specified 300 mW power dissipation limit on standard PCB footprints.
Part Context
