1N4733A TR TIN/LEAD

Single Zener Diodes Overview

The Central Semiconductor Corp 1N4733A TR TIN/LEAD is a silicon unidirectional voltage regulator diode designed for through-hole mounting in the DO-41 package. It provides a nominal Zener voltage of 5.1 V with a tolerance of 5%. The device features a maximum power dissipation of 1 W and operates within a temperature range from -65 °C to +200 °C. Key electrical characteristics include a maximum reverse leakage current of 10 uA, a Zener impedance of 7 Ohms, and a test current of 49 mA.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 5.1 V reference level
• Constructed using silicon planar technology for reliable performance
• Capable of handling high junction temperatures up to 200 °C
• Features low dynamic impedance for effective noise suppression

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in electronic systems
• General-purpose clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify compliance status as specific RoHS documentation indicates non-compliance for this variant. Confirm lead content due to the TIN/LEAD designation. Ensure the ordering suffix matches the required packaging configuration. Cross-reference datasheets from authorized distributors to validate current manufacturing status and availability constraints before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a standard 5.1 V regulation point is required in through-hole designs. Consider the 1 W power rating for thermal management requirements. Verify that the DO-41 package dimensions fit the target PCB layout. Compare specifications against alternative manufacturers if stricter environmental compliance or different packaging formats are necessary for the application.

Single Zener Diodes Part Context

This part belongs to the industry-standard 1N47 series of power Zener diodes. These components are widely used for basic voltage regulation tasks. The 1N4733A specifically denotes the 5.1 V variant within this family. Central Semiconductor manufactures this component to meet established JEDEC mechanical outline standards for axial leaded packages.

Single Zener Diodes Replacement Considerations

Compatible substitutes include Vishay 1N4733A, onsemi 1N4733A, and Nexperia 1N4733A. Ensure replacement parts match the DO-41 package and 5% voltage tolerance. Verify that alternative sources offer equivalent power dissipation and temperature ratings.
