Overview
The AZ23C4V3-TP is a dual common anode Zener diode manufactured by Micro Commercial Components (MCC). It integrates two independent Zener diodes within a single SOT-23-3 surface-mount package. The device provides a nominal Zener voltage of 4.3 V with a power dissipation rating of 300 mW. Key electrical characteristics include a maximum reverse leakage current of 100 nA and a Zener impedance of 95 Ohms at a test current of 5 mA. The component operates reliably across a temperature range from -65°C to +150°C, featuring a low voltage temperature coefficient of -0.035 %/°C for stable performance in varying thermal conditions.
Feature Summary
- Dual common anode configuration allows for compact circuit design using a single three-terminal package.
- High reliability operation supported by extended junction temperature range up to 150°C.
- Low leakage current specification ensures minimal power loss in high-impedance applications.
Applications
- Voltage reference circuits requiring precise dual rail generation.
- Clamping and protection stages in signal conditioning paths.
- Biasing networks in portable electronic devices.
Procurement Notes
Verify the manufacturer marking and lot code against official MCC documentation to ensure authenticity. Confirm that the specific suffix matches the required tolerance and packaging format. Cross-reference the datasheet parameters with system requirements before finalizing procurement orders.
Selection Notes
Select this component when space constraints necessitate a dual-diode solution in an SOT-23-3 footprint. Ensure the application voltage does not exceed the 300 mW power dissipation limit at the maximum operating temperature. Verify compatibility with standard reflow soldering profiles for lead-free assembly processes.
Part Context
This part belongs to the AZ23C series of dual Zener diodes offered by Micro Commercial Components. The series utilizes advanced silicon planar technology to achieve tight voltage tolerances. It serves as a cost-effective alternative to discrete dual-diode arrangements in consumer and industrial electronics.
Replacement Considerations
The Diodes Incorporated AZ23C4V3-7-F is a publicly confirmed substitute offering identical pinout and electrical specifications. Verify package dimensions and marking codes when transitioning between manufacturers to ensure mechanical fit.
