Overview
The AZ23C39 RFG is a dual common anode Zener diode array manufactured by Taiwan Semiconductor. It features two independent Zener elements within a single SOT-23-3 surface-mount package. The device provides a nominal Zener voltage of 39V with a tight tolerance of ±5%. It is rated for a maximum power dissipation of 300mW and operates across a wide temperature range from -55°C to +150°C. The component utilizes matte tin lead finish, ensuring compliance with halogen-free and Pb compound standards.
Feature Summary
- Dual common anode configuration integrates two Zener diodes into a compact footprint.
- High precision voltage regulation achieved through ±5% tolerance specification.
- Robust thermal performance supports operation in extreme ambient temperatures up to 150°C.
Applications
- Voltage reference circuits requiring stable dual supply rails
- Transient voltage suppression in signal conditioning paths
- Over-voltage protection for low-power electronic subsystems
Procurement Notes
Verify the specific suffix 'RFG' against the manufacturer's current datasheet to confirm packaging details and availability status. Ensure that the ordering information matches the exact electrical specifications required for the design, as suffixes may indicate variations in reel size or tape type rather than functional changes.
Selection Notes
Select this component when space-constrained designs require dual voltage clamping or referencing functions. The SOT-23-3 package offers a small outline suitable for high-density PCB layouts. Confirm that the 300mW power rating adequately handles the expected peak currents without exceeding thermal limits during continuous operation.
Part Context
This part belongs to the AZ23C series of dual Zener diodes produced by Taiwan Semiconductor. The series is characterized by its use in general-purpose electronics where reliable voltage regulation is needed in minimal space. The AZ23C39 specifically targets applications requiring a 39V breakdown voltage level.
Replacement Considerations
Cross-reference with other manufacturers offering dual common anode Zener arrays in SOT-23 packages. Verify pinout compatibility and ensure equivalent Zener voltage and power dissipation ratings before substituting.
