Overview
The AZ23C22 RFG is a dual common anode Zener diode array manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 22 V with a tolerance of ±5% and a maximum power dissipation of 300 mW. The device utilizes an SOT-23-3 surface-mount package, measuring 3.04 mm in length, 1.4 mm in width, and 1 mm in height. Electrical characteristics include a maximum reverse leakage current of 100 nA at 17 V and a Zener impedance of 55 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
- Compact SOT-23-3 surface-mount packaging
- High thermal stability across extended temperature ranges
Applications
- Voltage reference circuits requiring dual stable potentials
- Clamping applications in signal processing paths
- Over-voltage protection for sensitive semiconductor inputs
Procurement Notes
Verify the specific suffix RFG against official Taiwan Semiconductor documentation to confirm tape-and-reel specifications and moisture sensitivity levels. Ensure compatibility with automated pick-and-place equipment regarding the SOT-23-3 footprint dimensions. Cross-reference datasheet revisions to confirm compliance with current environmental directives before finalizing procurement orders.
Selection Notes
Select this component when a dual Zener solution is required in a minimal footprint. Compare the 55 Ohm Zener impedance against circuit requirements for dynamic regulation accuracy. Verify that the 300 mW power rating suffices for the expected thermal environment. Confirm that the 22 V breakdown voltage aligns with the target clamping or reference level.
Part Context
This part belongs to the AZ23 series of dual Zener arrays designed for compact electronic assemblies. The series offers standardized electrical characteristics across various voltage options within the same physical package. This specific variant provides a 22 V breakdown, serving as a standard reference point in the product line for general-purpose voltage regulation tasks.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Engineering validation is required before substituting with other manufacturers' dual Zener arrays to ensure pinout and electrical parameter compatibility.
