Overview
The AZ23C12 RFG is a dual common anode Zener diode array manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 12 V with a tolerance of ±5%. The device is designed for surface mount installation in an SOT-23 (SC-59) package, providing a maximum power dissipation of 300 mW. Key electrical parameters include a maximum reverse leakage current of 100 nA and a Zener impedance of 20 Ohms at a test current of 5 mA. The component operates within a junction temperature range of -55°C to +150°C.
Feature Summary
- Dual common anode configuration for efficient space utilization
- High thermal stability across extended temperature ranges
- Low leakage current characteristics for precision applications
Applications
- Voltage reference circuits requiring stable low-voltage sources
- Clamping and protection stages in signal processing paths
- Overvoltage protection for sensitive input lines
Procurement Notes
Verify the specific ordering suffix 'RFG' against the manufacturer's latest documentation to confirm packaging details such as reel size or tape-and-reel specifications. Ensure that the procurement channel provides traceability certificates if required for quality assurance protocols. Cross-reference the Mouser part number 821-AZ23C12RFG for availability status.
Selection Notes
Select this component when a dual Zener solution with a common anode is required in a compact SOT-23 footprint. The 300 mW power rating supports moderate current applications. Verify that the 12 V breakdown voltage aligns with the circuit's reference requirements and that the 20 Ohm impedance meets the noise and regulation constraints of the design.
Part Context
This part belongs to the AZ23C series of Zener diode arrays from Taiwan Semiconductor. The series offers various voltage options in standardized surface-mount packages. The 'RFG' suffix typically denotes specific packaging and marking configurations defined by the manufacturer for distribution channels.
Replacement Considerations
Direct substitutes include AZ23C12-TP from Micro Commercial Components and AZ23C12-AU_R2_100A1 from Panjit. These alternatives share identical pinouts, voltage ratings, and package dimensions, allowing for pin-compatible replacement without PCB layout changes.
