1N4732AW-TP

Overview

The MCC 1N4732AW-TP is a silicon planar power Zener diode designed for surface-mount applications. It features a nominal Zener voltage of 4.7 V with a tolerance of ±5%. The device dissipates up to 1.0 W of DC power at 25°C ambient temperature and operates within a junction temperature range of -55°C to +150°C. Packaged in the low-profile SOD-123 form factor, it exhibits a maximum reverse leakage current of 1 µA at 1 V and a forward voltage drop of 1.2 V at 200 mA.

Feature Summary

• Utilizes silicon planar technology for high stability and reliability
• Features a low-profile surface-mount package suitable for automated assembly
• Includes built-in strain relief on axial leads for mechanical robustness

Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage generation

Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm RoHS compliance status via packaging markings. Ensure storage conditions align with Level 1 moisture sensitivity ratings. Validate component traceability upon receipt.

Selection Notes

Select this component for designs requiring a 4.7 V reference in compact surface-mount layouts. Consider the 1.0 W power dissipation limit when calculating thermal management requirements. Verify that the SOD-123 footprint matches the PCB design constraints. Evaluate the ±5% voltage tolerance against circuit precision needs.

Part Context

This part belongs to the 1N4729AW through 1N4761AW series, which covers Zener voltages from 3.6 V to 75 V. All devices in this series share identical physical dimensions and electrical characteristics structure, differing primarily in their specific breakdown voltage ratings. The series is manufactured using silicon planar processes.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4732A equivalents in SOD-123 packages. Verify that substitute components meet the same 1.0 W power rating and 4.7 V nominal voltage specifications. Ensure thermal resistance and package dimensions are compatible with existing board layouts.
