1N4732A_S00Z

Overview

The onsemi 1N4732A is a single silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 4.7 V with a tolerance of 5%. The device supports a maximum power dissipation of 1 W and operates within an ambient temperature range of -65°C to +200°C. Key electrical parameters include a maximum reverse leakage current of 10 µA, a Zener impedance of 8 Ω at a test current of 53 mA, and a non-repetitive peak forward current rating of 970 mA. It is housed in a DO-41 (DO-204AL) axial through-hole package.

Feature Summary

• Provides stable voltage regulation with a nominal 4.7 V breakdown voltage.
• Capable of handling up to 1 W of power dissipation for robust performance.
• Features low reverse leakage current to minimize standby power loss.
• Constructed with high-temperature soldering capability for reliable assembly.

Applications

• Voltage reference circuits
• Overvoltage protection stages
• Power supply regulation

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact packaging or testing variations. Confirm RoHS compliance status as it varies by manufacturing origin. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a standard 4.7 V regulation point is required in through-hole designs. Consider the 5% tolerance and 8 Ω impedance for precision requirements. Evaluate thermal management needs given the 1 W dissipation limit in enclosed environments.

Part Context

This part belongs to the widely used 1N47 series of general-purpose Zener diodes. Manufactured by onsemi, it utilizes standard JEDEC DO-41 mechanical outlines. The series offers various voltage options from 3.3 V to higher values, maintaining consistent physical dimensions across the family.

Replacement Considerations

Equivalent parts include Nexperia 1N4732A, Central Semiconductor 1N4732D, and TAITRON Components 1N4732A. Verify pinout compatibility and ensure replacement devices meet the same 1 W power and 4.7 V voltage specifications.
