AZ23C2V7-E3-18

Overview

The AZ23C2V7-E3-18 is a dual silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a common anode configuration within a SOT-23 surface-mount package. The nominal Zener voltage is 2.7 V with a standard tolerance of ±5%. Electrical characteristics are defined at a test current of 5 mA, with 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 providing robust performance and reliability.
• RoHS-compliant commercial grade material categorization.

Applications

• Voltage reference circuits requiring low-voltage stabilization.
• Clamping applications for signal protection.
• Biasing networks in small-signal electronic systems.

Procurement Notes

Verify the ordering code suffix to confirm packaging specifications. The '-18' designation indicates taped units per reel, specifically 10,000 units on an 8 mm tape wound on a 13-inch reel. Confirm that the base part number corresponds to the required voltage tolerance and RoHS compliance status before finalizing procurement orders.

Selection Notes

Select this component when a dual Zener array with a common anode topology is required. The 'C' in the part number specifies a ±5% voltage tolerance; use 'B' variants if tighter ±2% tolerance is necessary. Ensure the application current does not exceed the specified test current of 5 mA to maintain accurate voltage regulation within the datasheet parameters.

Part Context

This device belongs to the AZ23 series of small signal Zener diodes from Vishay. The series offers a wide range of Zener voltages from 2.2 V to 75 V, all graded according to the international E24 standard. These components are designed for automatic insertion and provide consistent electrical characteristics across the operating temperature range.

Replacement Considerations

Direct parameter-equivalent replacements within the same manufacturer family include AZ23C2V7-E3-08 (different reel size) and AZ23C2V7-G3-18 (lead-free variant). Cross-manufacturer equivalents may exist but require verification of pinout compatibility and electrical limits against the original datasheet.
