Overview
The Vishay AZ23C2V4-G3-18 is a silicon planar Zener diode array featuring two common anodes in a SOT-23 package. It provides a nominal Zener voltage of 2.4 V with a ±5% tolerance, tested at 5 mA. The device has a maximum reverse leakage current of 50 μA and a dynamic resistance of 100 Ω at the test current. It operates within a temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- Silicon planar technology ensuring stable breakdown characteristics
- ESD protection capability exceeding 8 kV via human body model
Applications
- Voltage reference circuits requiring dual independent references
- Clamping applications for signal lines
- Protection against electrostatic discharge in portable electronics
Procurement Notes
Verify the specific ordering suffix '-18' confirms the 10,000-unit reel packaging format. Ensure compliance requirements match the 'G3' designation for lead-free and halogen-free standards. Confirm that the AEC-Q101 qualification status meets automotive application needs if applicable.
Selection Notes
Select this component when a dual common anode topology is required within a compact SOT-23 footprint. The 2.4 V nominal voltage suits low-voltage reference or clamping tasks. Verify that the 100 Ω dynamic resistance aligns with the noise and regulation requirements of the target circuit design.
Part Context
This part belongs to the AZ23-G series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.2 V to 75 V. The 'C' in the part number indicates the standard ±5% voltage tolerance grade.
Replacement Considerations
AZ23B2V4-G3-18 (offers tighter ±2% tolerance)
