Overview
The AZ23C3V9-G3-08 is a dual common anode small signal Zener diode array manufactured by Vishay Semiconductors. It features a nominal Zener voltage of 3.9 V with a ±5% tolerance, tested at a current of 5 mA. The device operates within a junction temperature range of -55 °C to +150 °C and dissipates up to 300 mW on an FR-4 board. Packaged in a surface-mount SOT-23 housing, it provides ESD protection exceeding 8 kV via the human body model and 800 V via the machine model.
Feature Summary
- Dual common anode configuration for space-efficient circuit designs
- Silicon planar construction ensuring robust performance
- High electrostatic discharge (ESD) immunity ratings
Applications
- Voltage reference circuits requiring dual stable potentials
- Clamping applications for protecting sensitive inputs
- General-purpose switching and logic level shifting
Procurement Notes
Verify the specific ordering code suffix against official documentation to confirm reel size and tape specifications. Ensure that the component meets RoHS compliance requirements for your manufacturing process. Cross-reference the manufacturer's latest datasheet revision to validate all electrical parameters before finalizing procurement orders.
Selection Notes
Select this component when a dual common anode topology is required within a compact SOT-23 footprint. The 3.9 V nominal rating suits low-voltage reference or clamping tasks. Verify that the 300 mW power dissipation capability aligns with the thermal constraints of the target printed circuit board layout.
Part Context
This part belongs to the AZ23-G series of small signal Zener diodes from Vishay. The series offers various voltage grades according to the E24 standard. The 'C' designation indicates a standard 5% voltage tolerance, while the 'G3' suffix denotes green commercial grade packaging without halogenated flame retardants.
Replacement Considerations
AZ23B3V9-G3-08: Offers tighter ±2% voltage tolerance compared to the standard 5% tolerance of the AZ23C variant.
