AZ23C15 RFG

Overview

The AZ23C15 RFG is a dual common anode Zener diode array manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 15 V with a tolerance of ±5% and a maximum power dissipation of 300 mW. The device is housed in a surface-mount SOT-23 package (TO-236-3, SC-59). Key electrical specifications include a maximum Zener impedance (Zzt) of 30 Ohms and a reverse leakage current of 100 nA at 11 V. The component operates within a junction temperature range of -55°C to 150°C and complies with RoHS 3 standards.

Feature Summary

• Dual configuration with common anode topology for efficient circuit layout
• Surface-mount SOT-23 packaging optimized for space-constrained applications
• High thermal stability supporting operation up to 150°C junction temperature

Applications

• Voltage reference circuits requiring dual regulated rails
• Transient voltage suppression in low-power signal lines
• Clamping applications in portable electronic devices

Procurement Notes

Verify the manufacturer part number AZ23C15 RFG against official Taiwan Semiconductor documentation to ensure authenticity. Confirm that the specific suffix matches the required RoHS 3 compliance status. Cross-reference the SOT-23 package marking codes with the datasheet to prevent counterfeit substitution during assembly.

Selection Notes

Select this component when a dual Zener array with a 15 V nominal voltage is required in a compact SOT-23 footprint. Ensure the design accounts for the 300 mW power dissipation limit and the 30 Ohm impedance characteristic. Verify that the ±5% voltage tolerance aligns with the precision requirements of the target application circuit.

Part Context

This device belongs to the AZ23C series of Zener diode arrays from Taiwan Semiconductor. The series offers various voltage options within the same SOT-23 package form factor, allowing designers to standardize on a single package type while adjusting voltage levels through different model suffixes.

Replacement Considerations

Direct substitutes include the AZ23C15-E3-08 from Vishay General Semiconductor. Alternative sourcing may involve checking Diodes Incorporated's AZ23C15-7-F, though parameter verification against the original datasheet is mandatory.
