Overview
The AZ23C9V1-G3-18 is a dual common anode silicon planar Zener diode array from the AZ23-G series, manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 9.1 V with a standard tolerance of ±5%. The device operates within a test current range of 0.1 to 5 mA and provides a maximum reverse leakage current of 0.1 µA at 7 V. Packaged in a compact SOT-23 surface-mount housing, it supports power dissipation up to 500 mW on leads and 300 mW on FR-4 boards. The component is RoHS compliant, halogen-free, and rated for operating temperatures between -55 °C and +150 °C.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- Zener voltages graded according to international E24 standards
- ESD protection capability exceeding 8 kV via human body model
- Green commercial grade material categorization
Applications
- Voltage reference circuits requiring dual polarity or split supplies
- Overvoltage protection for sensitive input lines
- Clamping applications in signal conditioning paths
Procurement Notes
Verify that the ordering suffix matches the required tape and reel specifications. The '-18' designation indicates units are supplied on a 13-inch reel with a minimum order quantity of 10,000 units. Confirm compliance requirements against the specific material categorization documentation provided by the manufacturer before finalizing procurement orders.
Selection Notes
Select this part when a dual common anode topology is necessary for voltage regulation or clamping tasks. Ensure the application voltage remains within the specified 9.1 V nominal range with ±5% tolerance. Verify thermal management capabilities align with the 300 mW dissipation limit on standard FR-4 substrates during continuous operation.
Part Context
