Overview
The AZ23C4V7 RFG is a dual Zener diode array manufactured by Taiwan Semiconductor Corporation. It features two independent Zener elements configured in a common cathode arrangement within a compact SOT-23 surface-mount package. The device provides a nominal Zener voltage of 4.7 V with a tolerance of ±5%. It is rated for a total power dissipation of 300 mW at ambient temperature, making it suitable for low-power voltage regulation and signal clamping applications in space-constrained electronic designs.
Feature Summary
- Dual Zener configuration in a single compact SOT-23 package
- Common cathode connection for simplified circuit layout
- ±5% voltage tolerance for precise regulation
- RoHS compliant construction
Applications
- Voltage reference circuits requiring dual rails
- Signal clipping and protection stages
- Portable electronics with limited board space
- Consumer appliance control boards
Procurement Notes
Verify the complete part number including the suffix to ensure correct packaging and compliance status. Confirm the specific revision level matches design requirements. Check manufacturer documentation for updated thermal derating curves. Ensure storage conditions align with moisture sensitivity level specifications. Validate supplier authenticity through authorized distribution channels.
Selection Notes
Select this component when dual isolated Zener references are needed in a minimal footprint. Compare total power dissipation limits against expected operating currents. Consider the common cathode topology for shared ground connections. Evaluate thermal performance under continuous load conditions. Verify compatibility with automated pick-and-place assembly processes.
Part Context
This component belongs to the AZ23C series of dual Zener diodes from Taiwan Semiconductor. The series offers various voltage options in the same SOT-23 form factor. It serves as a space-efficient alternative to discrete single Zener diodes. The family supports general-purpose voltage regulation tasks.
Replacement Considerations
Cross-reference with other SOT-23 dual Zener arrays offering 4.7 V common cathode configurations. Verify matching power ratings and tolerance levels before substitution. Check pinout compatibility to prevent circuit damage during replacement.
