1N4684UR-1

Single Zener Diodes Overview

The 1N4684UR-1 is a Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 3.3 V with a tolerance of 5%. The component operates in a surface-mount DO-213AA-2 package and supports through-hole mounting styles. Key electrical parameters include a maximum power dissipation of 500 mW, a maximum reverse leakage current of 7.5 uA, and a forward voltage of 1.1 V at a forward current of 200 mA. The device is rated for an operating temperature range from -65 C to +175 C.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation with a 3.3 V nominal Zener voltage.
• Capable of handling up to 500 mW power dissipation.
• Operates reliably across a wide temperature range from -65 C to +175 C.

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection systems
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific suffix UR-1 against official Microchip documentation to confirm the exact package type and hermetic sealing status, as variations exist within the 1N4684 series. Ensure compatibility with DO-213AA-2 footprints if surface mount assembly is required. Cross-reference datasheets for thermal management requirements given the 500 mW power rating.

Single Zener Diodes Selection Notes

Select this component when a precise 3.3 V reference is needed in compact surface-mount designs. Consider the 5% tolerance and low leakage current for sensitive analog applications. Verify that the operating environment stays within the specified -65 C to +175 C range to ensure long-term reliability and performance stability.

Single Zener Diodes Part Context

This part belongs to the 1N4684 series of Zener diodes produced by Microchip Technology. The series includes various packages such as DO-7-2 for through-hole and DO-213AA for surface-mount configurations. These diodes are commonly used in general-purpose electronics requiring reliable voltage clamping or regulation.

Single Zener Diodes Replacement Considerations

Check for direct substitutes like 1N4684UR or 1N4684UR-1E3 from Microchip or other manufacturers offering equivalent 3.3 V Zener diodes in DO-213AA packages. Ensure pinout and thermal characteristics match before substitution.
