Overview
The AZ23C5V1 is a dual surface-mount Zener diode array manufactured by Taiwan Semiconductor Corporation. It features a common anode configuration housed in an SOT-23 package. The nominal Zener voltage is 5.1 V with a tolerance of ±5%. Maximum power dissipation is rated at 300 mW, and the junction temperature range spans from -55°C to +150°C. Electrical specifications include a maximum Zener impedance (Zzt) of 60 Ohms at a test current of 5 mA, and a maximum reverse leakage current of 100 nA at 800 mV.
Feature Summary
- Dual Zener diodes integrated into a single compact SOT-23 package for space-efficient circuit designs.
- Common anode configuration simplifies biasing requirements for dual-channel voltage regulation applications.
Applications
- Low voltage stabilizers or voltage references
- Adapters
- Lighting applications
- On-board DC/DC converters
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and halogen-free status against IEC 61249-2-21 standards. Ensure packaging matches specified reel dimensions for automated assembly processes. Validate marking codes corresponding to the specific voltage variant during incoming inspection.
Selection Notes
Select this component when a dual Zener array with a common anode topology is required within an SOT-23 footprint. Verify that the 5.1 V nominal voltage and ±5% tolerance align with circuit design specifications. Ensure the 300 mW power dissipation rating accommodates thermal constraints in the target application environment.
Part Context
This device belongs to the AZ23C series, which offers a wide selection of Zener voltages ranging from 2.7 V to 51 V. All variants share identical mechanical characteristics, including the SOT-23 package and 300 mW power rating, allowing for standardized board layouts across different voltage reference designs.
Replacement Considerations
Cross-reference with other manufacturers offering dual common anode Zener arrays in SOT-23 packages. Verify matching electrical parameters, specifically the 5.1 V Zener voltage, 300 mW power rating, and 60 Ohm impedance limit, before substitution.
FAQ
What is the maximum reverse leakage current for the AZ23C5V1?
The maximum reverse leakage current is 100 nA, measured at a reverse voltage of 800 mV.
Does the AZ23C5V1 meet moisture sensitivity requirements?
Yes, the device meets Moisture Sensitivity Level 1 per J-STD-020, indicating it is not susceptible to moisture-induced damage during standard reflow soldering processes.
What is the testing condition for the Zener voltage specification?
The Zener voltage (Vz) is tested under pulse conditions with a duration of 5 ms to minimize self-heating effects during measurement.
