Overview
The AZ23C2V7-E3-08 is a dual common anode silicon planar Zener diode from the Vishay AZ23 series, housed in a surface-mount SOT-23 package. It provides two independent Zener diodes sharing a common anode terminal within a single component. The nominal Zener voltage is 2.7 V with a standard tolerance of ±5%. Electrical characteristics are specified at a test current of 5 mA, featuring a maximum reverse leakage current of 20 µA and a dynamic resistance of 83 Ω. The device supports a power dissipation of up to 500 mW and operates across a temperature range of -55 °C to +150 °C.
Feature Summary
- Dual Zener diodes integrated in a single common anode configuration for space-efficient circuit design.
- Silicon planar construction optimized for automated surface-mount assembly processes.
- Standardized E24 grading with ±5% voltage tolerance for consistent performance.
Applications
- Voltage reference circuits requiring dual supply rails or split power supplies.
- Over-voltage protection stages utilizing shared ground references.
- Signal clamping applications protecting multiple input lines from a common node.
Procurement Notes
Verify the specific suffix against the manufacturer's ordering code table to confirm tape-and-reel specifications and minimum order quantities. Ensure the procurement documentation explicitly states RoHS compliance and commercial grade status, as these attributes are tied to the base part number designation rather than assumed.
Selection Notes
Select this component when a dual Zener array with a shared anode is required in a compact SOT-23 footprint. Confirm that the 2.7 V nominal voltage aligns with the circuit requirements and that the ±5% tolerance meets the design margins. Evaluate the thermal resistance parameters if operating near the maximum power dissipation limits.
Part Context
This part belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V in various tolerance grades. The AZ23C2V7 variant specifically targets low-voltage dual-diode applications within the commercial product line.
Replacement Considerations
Cross-reference with other manufacturers offering dual common anode Zener arrays in SOT-23 packages. Verify matching electrical parameters such as Zener voltage, tolerance, and package dimensions before substitution.
FAQ
