1N4733A_S00Z

Single Zener Diodes Overview

The onsemi 1N4733A_S00Z is a silicon planar Zener diode housed in a DO-41 glass case. It provides voltage regulation with a nominal Zener voltage of 5.1 V and a tolerance of ±5%. The device dissipates up to 1.0 W at a lead temperature of 50°C, derating linearly above this threshold. Key electrical characteristics include a maximum dynamic impedance of 7 Ω at the test current of 49 mA and a leakage current not exceeding 1 µA at 1 V. It withstands non-repetitive peak reverse currents up to 890 mA.

Single Zener Diodes Feature Summary

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required packaging configuration. Confirm compliance with specific environmental standards if applicable to the end-use environment. Ensure the component meets all absolute maximum ratings for the intended thermal conditions during operation.

Single Zener Diodes Selection Notes

Select this component when a standard 5.1 V regulation point is required within a DO-41 package. Consider the 1.0 W power dissipation limit and the need for adequate heat sinking or airflow if operating near maximum ratings. Verify that the 5% tolerance aligns with the circuit's precision requirements.

Single Zener Diodes Part Context

This part belongs to the 1N4728A through 1N4758A series of 1.0 Watt Zener Diodes manufactured by onsemi. The series covers a broad voltage range from 3.3 V to 100 V, utilizing a consistent DO-41 glass package format across the lineup for standardized mounting and handling.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N4733A equivalents. Verify that substitute parts meet the same 5.1 V nominal voltage, 5% tolerance, and 1.0 W power dissipation specifications in the DO-41 package.
