1N5066

Single Zener Diodes Overview

The 1N5066 is a Zener diode manufactured by Microchip Technology, designed for voltage regulation and reference applications. It features a nominal Zener voltage of 9.1 V with a tolerance of ±5%. The component is rated for a power dissipation of 3 W and utilizes a through-hole axial package configuration.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation at a specific nominal potential
• Capable of handling significant power dissipation in through-hole configurations
• Offers precise voltage tolerance for reliable circuit performance

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection
• Power supply regulation

Single Zener Diodes Procurement Notes

Verify the manufacturer designation as Microchip Technology or its acquired entities, such as DIGI (Digitron Semiconductors), to ensure authenticity. Confirm the package type is axial leaded and matches the required PCB footprint. Ensure the voltage rating is exactly 9.1 V with ±5% tolerance. Check for RoHS compliance status if required by project specifications. Validate the power rating is 3 W for thermal management planning.

Single Zener Diodes Selection Notes

Select this component when a 9.1 V regulated reference is needed in a high-power through-hole application. Consider the axial package constraints for board layout. Evaluate thermal requirements given the 3 W dissipation capability. Compare against other Zener voltages if the system requires different reference levels. Ensure the ±5% tolerance meets the circuit's precision requirements.

Single Zener Diodes Part Context

This part belongs to the standard Zener diode family, often associated with historical JEDEC numbering schemes. Microchip Technology produces these components, continuing legacy lines from acquired semiconductor manufacturers. The 1N5066 is distinct from switching controllers or rectifiers found in similar naming conventions.

Single Zener Diodes Replacement Considerations

Check for equivalents from Digitron Semiconductors under the same 1N5066 designation. Verify that any substitute maintains the 9.1 V Zener voltage, 3 W power rating, and ±5% tolerance. Ensure the replacement uses an axial through-hole package compatible with existing footprints.
