1N4734A-T50R

Single Zener Diodes Overview

The onsemi 1N4734A-T50R is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 5.6 V with a tolerance of ±5%. The device operates in the DO-41-2 through-hole package and dissipates up to 1 W of power. Key electrical parameters include a maximum reverse leakage current of 10 µA, a Zener impedance of 9 Ω, and a test current of 49 mA. It supports a wide operating temperature range from -65 °C to +200 °C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a nominal 5.6 V level
• Capable of handling 1 W power dissipation in a standard axial leaded package
• Engineered for reliable operation across an extended industrial temperature range

Single Zener Diodes Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in electronic systems
• General-purpose voltage regulation in power supplies

Single Zener Diodes Procurement Notes

Verify the specific suffix T50R corresponds to the tape and reel packaging format containing 3000 units per reel. Confirm that the manufacturer designation matches onsemi specifications rather than other vendors using similar part numbers. Ensure the component meets required RoHS compliance standards for the intended assembly process.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V regulation point is required with moderate power handling capabilities. The DO-41-2 package suits through-hole mounting techniques. Consider the 9 Ω impedance value for dynamic regulation requirements and ensure the thermal environment supports 1 W dissipation without exceeding the maximum junction temperature limits defined in the datasheet.

Single Zener Diodes Part Context

This component belongs to the 1N47xx series of Zener diodes, widely used for basic voltage clamping and reference functions. The 1N4734A variant specifically targets the 5.6 V market segment. The T50R suffix indicates a specific bulk or tape-and-reel packaging configuration offered by onsemi for automated assembly processes.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1N4734A-T50A and 1N4734ATR from onsemi, which share identical electrical characteristics but may differ in packaging format. Other manufacturers producing the 1N4734A specification can be considered if pinout and thermal performance match.
