Overview
The AZ23C4V7-TP is a Zener diode manufactured by Micro Commercial Components (MCC). It operates within a voltage range of 4.4 V to 5.0 V at the nominal 4.7 V designation. The component features a maximum power dissipation of 300 mW and a Zener impedance of 500 Ohms. Reverse leakage current is specified at 0.1 µA. It is housed in an SOT-23 surface-mount package, suitable for automated assembly processes.
Feature Summary
- Dual common anode configuration within a single compact package
- Tight voltage matching between internal diodes with delta Vz less than or equal to 5 percent
- Designed for high-volume automated placement applications
Applications
- Voltage reference circuits requiring matched dual diodes
- Clamping and protection stages in signal conditioning paths
- Biasing networks in low-power electronic modules
Procurement Notes
Verify the specific suffix against official MCC documentation to confirm exact electrical tolerances and packaging variants. Ensure compatibility with standard SOT-23 footprint dimensions during PCB layout. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before final procurement approval.
Selection Notes
Select this component when a matched pair of Zener diodes is required in a minimal footprint. The 300 mW rating supports moderate current levels in low-power designs. Verify that the 500 Ohm impedance aligns with the noise and regulation requirements of the target application circuit.
Part Context
This part belongs to the AZ23C series of Zener arrays from Micro Commercial Components. These devices integrate two diodes in one package to save board space. The series targets consumer electronics and industrial control systems where size constraints are critical.
Replacement Considerations
Cross-reference with AZ23C4V7W-TP for potential variations in power rating or tolerance. Check AZ23C4V7HE3-TP for lead-free specific manufacturing updates. Verify pinout compatibility with existing SOT-23 layouts before substitution.
