Overview
The Taiwan Semiconductor AZ23C39 is a dual common anode Zener diode array housed in an SOT-23 package. It provides a nominal Zener voltage of 39V with a tolerance of ±5%, operating within a range of 37V to 41V. The device features a maximum power dissipation of 300mW and operates across a junction temperature range of -55°C to +150°C. Electrical characteristics include a Zener impedance of 90Ω at a test current of 5mA, a leakage current of 1µA at 29V reverse voltage, and a thermal resistance of 420°C/W.
Feature Summary
- Dual Zener diodes integrated into a single common anode configuration for space-efficient circuit design.
- Moisture sensitivity rated at Level 1 per J-STD-020 standards, supporting automated assembly processes.
- Halogen-free construction compliant with IEC 61249-2-21 requirements.
Applications
- Low voltage stabilizers or voltage references
- Adapters
- Lighting applications
- On-board DC/DC converters
Procurement Notes
Verify the specific ordering suffix (e.g., RF, RFG) to confirm packaging details such as reel size and tape specifications. Confirm RoHS compliance status and halogen-free designation through official documentation before procurement. Ensure the component meets the required moisture sensitivity level for the intended manufacturing process.
Selection Notes
Select this component when a dual Zener array with a common anode topology is required for voltage regulation tasks. Verify that the 300mW power dissipation rating and 39V nominal voltage align with the circuit's operational limits. Consider the SOT-23 footprint constraints and the ±5% voltage tolerance during the schematic design phase.
Part Context
The AZ23C39 belongs to the AZ23C series, which encompasses dual SMD Zener diodes ranging from 2.7V to 51V. This series is designed for surface mount technology applications requiring compact solutions for voltage reference and stabilization functions in consumer and industrial electronics.
Replacement Considerations
Direct replacements must match the dual common anode configuration, 39V nominal voltage, and SOT-23 package. Verify equivalent electrical parameters including power dissipation and impedance. Cross-reference with other manufacturers offering similar dual Zener arrays if availability is constrained.
