Overview
The AZ23C24 RFG is a dual common anode Zener diode manufactured by Taiwan Semiconductor Corporation. It features two independent Zener elements within a single SOT-23 (R-PDSO-G3) plastic package, providing a compact solution for voltage regulation and protection circuits. The device is rated for a total power dissipation of 300 mW at ambient temperature. The nominal Zener voltage is specified at 24 V with a tolerance of ±5%. It operates reliably across a junction temperature range from -55 °C to +150 °C. The component utilizes a matte tin lead finish and is compliant with RoHS directives.
Feature Summary
- Dual common anode configuration integrates two Zener diodes in one package
- Compact SOT-23 surface mount footprint suitable for automated assembly
- High thermal stability with maximum operating junction temperature of 150 °C
- Lead-free construction with matte tin plating for solderability
Applications
- Voltage reference generation in low-power electronic circuits
- Transient voltage suppression for signal lines
- Clamping applications in portable consumer devices
Procurement Notes
Verify the specific suffix 'RFG' against the manufacturer's current datasheet to confirm packaging details and availability status. Check for obsolescence notices as some variants in this series may carry 'NRND' designations. Ensure compliance requirements match project specifications regarding halogen-free content and moisture sensitivity levels before procurement.
Selection Notes
Select this component when space-constrained designs require dual voltage references or clamping functions. Verify that the 24 V breakdown voltage aligns with circuit requirements. Confirm that the 300 mW power rating is sufficient for the expected current levels. Compare pinout compatibility if replacing existing components in established layouts.
Part Context
This part belongs to the AZ23C series of dual Zener diodes offered by Taiwan Semiconductor. The series provides various voltage options within the same SOT-23 package family. These components are designed for general-purpose voltage regulation tasks where board space is limited. The common anode structure allows for efficient use of PCB area compared to discrete single diodes.
Replacement Considerations
Cross-reference with Vishay AZ23C24-E3-18 or Micro Commercial Components AZ23C24WHE3-TP for functional equivalents. Verify pinout alignment and electrical parameter tolerances before substitution. Ensure the replacement part meets the same thermal and mechanical specifications required by the original design.
