1N4733A_S00Z

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.

Feature Summary

• Hermetically sealed double slug type construction for reliable performance
• Oxide passivated die design for enhanced stability
• Wide operating and storage temperature range capability

Applications

• Voltage regulation circuits
• Voltage reference applications
• Surge protection devices

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.

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.

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.

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.
