1N4735ATR

Overview

The onsemi 1N4735ATR is a single-channel general-purpose Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 6.2 V with a tolerance of ±5%. The device operates in the DO-41 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 2 Ω, and a test current of 41 mA. It functions within an operating temperature range from -65 °C to +200 °C.

Feature Summary

• Provides stable voltage regulation at a nominal 6.2 V level
• Capable of handling 1 W power dissipation in a standard axial leaded package
• Offers low dynamic impedance for effective noise suppression

Applications

• General purpose voltage reference circuits
• Overvoltage protection stages
• Power supply output regulation

Procurement Notes

Verify the specific suffix 'ATR' corresponds to the required reel or cut tape packaging format for automated assembly lines. Confirm RoHS compliance status as indicated in official datasheets before finalizing procurement specifications. Ensure the manufacturer designation matches onsemi requirements for quality assurance protocols.

Selection Notes

Select this component when a 6.2 V regulation point is required with moderate precision. The DO-41 package suits manual soldering or wave soldering processes. Consider the 5% tolerance and thermal characteristics against circuit load requirements to ensure reliable operation across the specified temperature range.

Part Context

This part belongs to the widely recognized 1N47 series of silicon Zener diodes. These components are standardized for industrial and commercial electronics. The ATR suffix typically denotes bulk reel packaging, distinguishing it from tape-and-reel or bulk box variants within the same electrical specification family.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4735A equivalents. Verify that substitute parts maintain identical 6.2 V Zener voltage, 1 W power rating, and DO-41 mechanical dimensions to ensure direct compatibility without circuit redesign.
