Overview
The AZ23C27 RFG is a small signal Zener diode manufactured by Taiwan Semiconductor, belonging to the AZ23C series. It features a nominal Zener voltage of 27V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 300mW at ambient temperatures up to 75°C. It utilizes an SOD-123 surface-mount package and is designed for general-purpose voltage regulation and clipping applications in compact electronic circuits.
Feature Summary
- Compact SOD-123 surface-mount package design suitable for automated assembly
- Stable voltage regulation performance within specified temperature ranges
- High reliability construction for general-purpose circuit protection
Applications
- Voltage reference circuits requiring stable 27V levels
- Over-voltage protection in low-power consumer electronics
- Clipping and clamping applications in signal processing paths
Procurement Notes
Verify the complete part number including the RFG suffix to ensure correct packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference datasheet electrical characteristics against specific circuit requirements to validate thermal management needs under operational load conditions.
Selection Notes
Select this component when a 27V Zener voltage with 5% tolerance is required in a small footprint. Ensure the application current remains within limits defined by the 300mW power dissipation rating. Consider thermal derating factors if operating above standard ambient temperature specifications.
Part Context
This device is part of the AZ23C family of small signal Zener diodes from Taiwan Semiconductor. The series offers various voltage options in the same SOD-123 package to simplify supply chain management. The AZ23C27 specifically targets applications needing precise voltage referencing in space-constrained designs.
Replacement Considerations
Direct substitutes include other manufacturers' SOD-123 packaged 27V Zener diodes with comparable power ratings. Verify pinout compatibility and thermal resistance values before substitution. Check for equivalent dynamic impedance specifications to maintain circuit stability.
