1N4735AT9-E

Overview

The 1N4735AT9-E is a single silicon Zener diode manufactured by Renesas Electronics Corporation. It provides voltage regulation with a nominal Zener voltage of 6.2 V and a maximum power dissipation of 1 W. The component utilizes the DO-41 through-hole package, featuring two pins for circuit integration. It operates within a temperature range from -65°C to +200°C and carries an ECCN classification of EAR99.

Feature Summary

• Provides stable voltage regulation using a single silicon junction structure
• Designed for through-hole mounting in standard DO-41 plastic packages
• Capable of handling high thermal loads up to 200°C operating temperatures

Applications

• General-purpose voltage regulation circuits
• Power supply reference voltage generation
• Over-voltage protection stages

Procurement Notes

Verify the manufacturer designation as Renesas Electronics Corporation against official datasheets. Confirm the specific suffix AT9-E requirements for your application. Check RoHS compliance status as it may be marked as not applicable or non-compliant depending on the revision. Ensure the DO-41 package dimensions match your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a 6.2 V reference point is required in through-hole designs. Consider the 1 W power rating for thermal management needs. Verify that the -65°C to +200°C temperature range meets environmental specifications. Compare against other 1N47 series variants if different voltage tolerances are needed.

Part Context

This part belongs to the widely recognized 1N47 series of Zener diodes, which offers extensive voltage selections ranging from 3.3 V to 100 V. The series is known for providing reliable voltage regulation in general electronic applications. Renesas continues production of these legacy parts to support existing industrial and commercial hardware designs requiring standardized through-hole components.

Replacement Considerations

Compatible substitutes include the 1N4735A from onsemi and the MX1N4735CPTR from Microsemi. These alternatives share identical electrical characteristics and DO-41 packaging. Verify pinout compatibility and thermal performance ratings before substituting in critical circuits.
