1N4766A

Single Zener Diodes Overview

The Microchip Technology 1N4766A is a temperature-compensated Zener reference diode with a nominal voltage of 9.1 V and a power dissipation rating of 500 mW. It utilizes the DO-204AA (DO-35) axial leaded package. The device features a voltage tolerance of 5% and a maximum reverse leakage current of 10 µA. Designed for precision applications, it offers stable performance across varying thermal conditions.

Single Zener Diodes Procurement Notes

Verify the manufacturer origin, as this part number is produced by multiple vendors including Microchip and Microsemi. Confirm the specific suffix requirements, such as /TR for tape-and-reel packaging, against your assembly needs. Ensure the DO-35 package style matches your board layout constraints before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a stable 9.1 V reference is required in an axial package. The 500 mW power rating suits low-current applications. Consider the 5% tolerance if tighter regulation is not critical. Verify compatibility with existing circuit designs requiring temperature-compensated behavior rather than standard Zener characteristics.

Single Zener Diodes Part Context

This component belongs to the 1N47xx series of Zener diodes, widely used for voltage regulation and protection. The 1N4766A specifically targets applications needing temperature stability. It serves as a discrete alternative to integrated voltage references in cost-sensitive or simple analog designs.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N4766A equivalents from sources like Microsemi or Vishay. Ensure replacement parts maintain the 9.1 V nominal voltage and 500 mW power rating. Verify package compatibility and tolerance specifications match the original design requirements.
