AZ23C3V0-E3-08

Overview

The AZ23C3V0-E3-08 is a dual common anode silicon planar Zener diode array from the Vishay AZ23 series, housed in a SOT-23 package. It features a nominal Zener voltage of 3.0 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 10 μA at 1 V and a dynamic resistance of 95 Ω at 5 mA.

Feature Summary

• Dual common anode configuration for space-efficient circuit designs
• ESD robustness compliant with AEC-Q101 standards
• RoHS-compliant commercial grade construction

Applications

• Voltage reference circuits requiring dual low-voltage regulation
• Input protection stages for sensitive electronic components
• Clamping applications in signal conditioning paths

Procurement Notes

Verify component authenticity by cross-referencing the ordering code against official Vishay documentation. Confirm that the specific suffix matches the required tape-and-reel packaging format and tolerance class before finalizing acquisition.

Selection Notes

Select this part when a dual common anode topology is necessary for low-voltage clamping or referencing. Ensure the 300 mW thermal rating on standard PCBs meets the application's power dissipation requirements under expected operating conditions.

Part Context

This component belongs to the AZ23 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series offers various voltage grades and tolerance options within the compact SOT-23 footprint, catering to general-purpose surface-mount electronics.

Replacement Considerations

Direct substitutes within the same family include AZ23B3V0-E3-08 for tighter tolerance or AZ23C3V0-G3-08 for alternative packaging variants. Verify pinout compatibility and electrical parameters before substitution.
