Overview
The AZ23C11 RFG is a dual Zener diode manufactured by Taiwan Semiconductor Corporation, housed in an SOT-323 plastic-encapsulated surface-mount package. This component integrates two independent Zener diodes within a single common-anode configuration, allowing for efficient space utilization on printed circuit boards. The device is designed for voltage regulation and protection applications, offering a power dissipation rating of 200mW at 25°C ambient temperature. It features a tight matching tolerance where the difference in Zener voltage (△Vz) between the two diodes is less than or equal to 5%. The component supports automatic insertion processes and is available in lead-free versions compliant with environmental standards.
Feature Summary
- Dual Zener diodes integrated in a single common-anode configuration
- Compact SOT-323 plastic-encapsulated surface-mount package
- Tight voltage matching with △Vz ≤ 5% for both diodes
- Suitable for automated assembly and insertion processes
Applications
- Voltage reference circuits requiring dual regulated rails
- Transient voltage suppression in compact electronic devices
- Clamping applications in signal processing lines
Procurement Notes
Verify the specific ordering suffix 'RFG' against the manufacturer's current datasheet to confirm packaging details such as tape-and-reel specifications. Ensure that the requested part matches the required Zener voltage tolerance and thermal characteristics for the intended operating environment. Confirm lead-free compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this component when space constraints necessitate a dual-diode solution in an SOT-323 footprint. Consider the common-anode topology for circuit design compatibility. Verify that the 200mW power dissipation rating meets the thermal requirements of the application. Check for alternative common-cathode configurations if the circuit design requires a different polarity arrangement.
Part Context
The AZ23C series from Taiwan Semiconductor includes various Zener voltage options ranging from low voltages up to higher breakdown values. These components are part of a broader family of small-signal diodes designed for general-purpose switching and regulation. The SOT-323 package is widely used in portable electronics due to its small outline and high pin density capabilities.
Replacement Considerations
Check for direct substitutes from other manufacturers offering identical SOT-323 dual Zener packages with common-anode configurations. Verify electrical parameter equivalence, specifically Zener voltage tolerance and power dissipation ratings, before substituting.
