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.
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.
Applications
- Voltage regulation circuits
- Overvoltage protection systems
- Reference voltage generation
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.
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.
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.
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.
