AZ23C16-E3-08

Overview

The AZ23C16-E3-08 is a dual common anode silicon planar Zener diode array manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 16 V with a tolerance of ±5%, tested at a current of 5 mA. The device has a maximum reverse leakage current of 50 nA and a dynamic resistance of 40 Ohms at the test current. It operates within a temperature range of -55 °C to +150 °C, dissipating up to 300 mW on an FR-4 board. The component is housed in a surface-mount SOT-23 package.

Feature Summary

• Dual common anode configuration for space-efficient circuit designs
• Silicon planar technology ensuring robust performance
• ESD protection capability exceeding 8 kV via human body model

Applications

• Voltage reference circuits requiring dual stable potentials
• Clamping applications for signal lines
• Protection stages against overvoltage transients

Procurement Notes

Verify the specific ordering code suffix to confirm the reel size and minimum order quantity requirements. Ensure that the commercial grade designation aligns with the intended application environment. Cross-reference the manufacturer part number with distributor databases to confirm current availability status before finalizing procurement plans.

Selection Notes

Select this component when a dual Zener array with a 16 V nominal voltage and ±5% tolerance is required. Consider the SOT-23 package constraints for PCB layout. Evaluate the thermal dissipation limits relative to the ambient operating conditions to ensure reliable operation within the specified junction temperature range.

Part Context

This device belongs to the AZ23 series of small signal Zener diodes from Vishay Semiconductors. The series offers a wide range of Zener voltages from 2.2 V to 75 V. The 'C' designation indicates a standard ±5% voltage tolerance, while the '-E3' suffix denotes RoHS compliance for commercial grade products.

Replacement Considerations

AZ23B16-E3-08 provides the same electrical characteristics but with a tighter ±2% voltage tolerance.
