AZ23C30-E3-18

Overview

The AZ23C30-E3-18 is a dual common anode Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 30 V with a tolerance of ±5%. The device operates within a test current range of 2 mA to 5 mA and has a maximum reverse leakage current of 50 µA at 22.5 V. Dynamic resistance is specified at 80 Ω, while the temperature coefficient ranges from 8 to 10 x 10⁻⁴/°C. Rated for a maximum power dissipation of 300 mW on an FR-4 board, it functions across an operating temperature range of -55 °C to +150 °C in a surface-mount SOT-23 package.

Feature Summary

• Dual common anode configuration for space-efficient circuit design
• Zener voltages graded according to international E24 standard
• ESD capability exceeding 8 kV (human body model) and 800 V (machine model)
• RoHS-compliant commercial grade construction

Applications

• Voltage reference circuits requiring dual independent references
• Clamping and protection stages in signal processing paths
• Biasing networks in low-power analog applications

Procurement Notes

Verify that the ordering code matches the required voltage tolerance and packaging format. Confirm RoHS compliance status and ensure the component meets specific environmental requirements for the intended application environment before finalizing procurement orders.

Selection Notes

Select this part when a dual common anode topology is required within a compact SOT-23 footprint. Ensure the operating current stays within the 2 mA to 5 mA range to maintain accurate voltage regulation and verify thermal constraints align with the 300 mW dissipation rating on standard PCBs.

Part Context

This component belongs to the AZ23 series of small signal Zener diodes produced by Vishay Semiconductors. The series offers a wide range of standardized Zener voltages from 2.2 V to 75 V. The 'E3' suffix indicates lead-free termination compliant with RoHS standards, while the '-18' suffix specifies tape-and-reel packaging containing 10,000 units per reel.

Replacement Considerations

Direct substitutes include other AZ23C30 variants such as AZ23C30-E3-08 or AZ23C30-G3-08, which share identical electrical characteristics but differ in packaging quantities. Cross-brand replacements must match the 30 V nominal voltage, ±5% tolerance, and SOT-23-3 pinout configuration.
