1N4767/TR

Single Zener Diodes Overview

The Microchip Technology 1N4767/TR is a single Zener diode housed in a DO-204AH (DO-35) axial through-hole package. It features a nominal Zener voltage of 9.1 V with a tolerance of ±5%. The device has a power dissipation rating of 500 mW and operates within a temperature range of -65°C to +175°C. Key electrical parameters include a maximum reverse leakage current of 100 nA, a Zener impedance of 175 ohms at a test current of 3.3 mA, and a forward current of 200 mA.

Single Zener Diodes Feature Summary

• Temperature compensated design for stable voltage regulation across wide thermal ranges
• Single configuration suitable for precision reference applications
• Through-hole axial mounting for robust mechanical integration

Single Zener Diodes Applications

• Voltage reference circuits requiring high stability
• Overvoltage protection in sensitive electronic systems
• Precision clipping and clamping applications

Single Zener Diodes Procurement Notes

Verify the specific suffix /TR indicates reel packaging when ordering. Confirm RoHS compliance status directly with the manufacturer or authorized distributors as regulatory requirements may vary by region and production batch. Ensure the DO-204AH package dimensions match your PCB footprint requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 9.1 V regulated voltage is required with low leakage characteristics. The 500 mW power rating limits its use in high-current scenarios compared to higher wattage variants. Consider the axial lead form factor for manual assembly or wave soldering processes where surface-mount alternatives are unsuitable.

Single Zener Diodes Part Context

This part belongs to the Microchip 1N47xx series of temperature-compensated Zener diodes. These devices are engineered to minimize voltage drift over temperature changes, making them distinct from standard Zener diodes. The series covers various voltage levels while maintaining consistent package and performance characteristics for interchangeable design platforms.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N4767 equivalents such as those from ON Semiconductor or Vishay. Verify that substitute parts meet the same 9.1 V nominal voltage, ±5% tolerance, and 500 mW power dissipation specifications to ensure circuit compatibility.
