Overview
The AZ23C2V7-G3-18 is a dual common-anode silicon planar Zener diode array from Vishay, housed in an SOT-23 package. It features a nominal Zener voltage of 2.7 V with a ±5% tolerance and a maximum power dissipation of 300 mW on an FR-4 board. The device operates within a temperature range of -55°C to +150°C and includes ESD protection exceeding 8 kV (HBM) and 800 V (MM). Electrical characteristics include a reverse leakage current of 20 μA at 1.7 V and a dynamic resistance of 83 Ω at the test current of 5 mA.
Feature Summary
- Dual common-anode configuration for efficient space utilization
- ESD robustness compliant with AEC-Q101 standards
- Green commercial grade construction without halogenated additives
Applications
- Voltage reference circuits requiring low-voltage stability
- Overvoltage protection for sensitive input lines
- Clamping applications in portable electronic devices
Procurement Notes
Verify component authenticity by cross-referencing the manufacturer's part number and datasheet revision against authorized distribution channels. Confirm that the ordering suffix matches the required reel quantity and tape specifications. Ensure compliance with RoHS3 directives and material categorization requirements before finalizing procurement orders.
Selection Notes
Select this component when a precise 2.7 V reference or clamping level is required in a compact surface-mount footprint. Consider the ±5% tolerance and 83 Ω dynamic resistance for circuit accuracy. Evaluate thermal management needs based on the 300 mW dissipation limit on standard PCBs.
Part Context
This device belongs to the AZ23-G series of small signal Zener diodes. The 'C' designation indicates a standard ±5% voltage tolerance, while the 'G3' suffix denotes green, commercial-grade packaging. The '-18' suffix specifies a 10,000-unit reel format on an 8 mm tape.
Replacement Considerations
AZ23B2V7-G3-18 offers tighter ±2% tolerance. AZ23C2V7-E3-18 provides equivalent electrical performance with different environmental compliance markings.
