1N4776A/TR

Single Zener Diodes Overview

The 1N4776A/TR is a temperature-compensated Zener diode manufactured by Microchip Technology. It features an 8.5 V nominal Zener voltage with a 5% tolerance and operates in the DO-35 (DO-204AH) through-hole package. The device dissipates 500 mW of power, with a maximum reverse leakage current of 10 µA and a Zener impedance of 200 Ohms. It functions within a temperature range of -65°C to +175°C and utilizes a reel packaging format.

Single Zener Diodes Feature Summary

• Temperature compensated design for stable voltage regulation across varying thermal conditions
• Single configuration suitable for precision reference applications
• Through-hole mounting capability in standard axial leaded packages

Single Zener Diodes Applications

• Precision voltage reference circuits requiring thermal stability
• Overvoltage protection in sensitive electronic systems
• Voltage regulator designs utilizing temperature-compensated references

Single Zener Diodes Procurement Notes

Verify the specific suffix /TR indicates reel packaging when ordering. Confirm RoHS compliance status as some variants may differ. Ensure the DO-35 package dimensions match your PCB footprint requirements. Check for any specific environmental certifications required by your supply chain standards before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 8.5 V reference is needed under fluctuating temperatures. The temperature compensation feature distinguishes it from standard Zener diodes. Ensure the 500 mW power rating meets the circuit's dissipation needs. Verify that the through-hole form factor aligns with the assembly process.

Single Zener Diodes Part Context

This part belongs to Microchip's 1N47xx series of Zener diodes. The 1N4776A variant specifically provides 8.5 V regulation. The /TR suffix denotes tape and reel packaging for automated assembly. It is distinct from non-compensated versions in the same voltage class.

Single Zener Diodes Replacement Considerations

Check for other 1N4776A variants with different suffixes if reel packaging is not required. Verify equivalent temperature-compensated Zener diodes from other manufacturers if Microchip supply is limited. Ensure replacement parts match the 8.5 V nominal voltage and DO-35 package constraints.
