Overview
The 1N4680UR-1 is a single silicon Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 2.2V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 0.5W and operates in a unidirectional configuration. It utilizes the DO-213AA package, also known as SOD-80 or MELF-2, constructed from hermetically sealed glass. The component supports an operating temperature up to 175°C and contains two terminals.
Feature Summary
- Hermetically sealed glass construction for environmental protection
- Unidirectional Zener voltage regulation capability
- High thermal stability supporting elevated operating temperatures
Applications
- Voltage reference circuits requiring stable low-voltage regulation
- Overvoltage protection in sensitive electronic systems
- Clamping applications in signal processing paths
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact electrical tolerances and packaging variations. Ensure compliance with relevant regulatory standards such as RoHS if required by the application environment. Cross-reference the DO-213AA package dimensions with PCB footprint specifications during integration planning.
Selection Notes
Select this component when a precise 2.2V regulation point is required within a surface-mount MELF-style package. Consider the 0.5W power rating and 175°C maximum junction temperature limits during thermal design. Verify that the unidirectional characteristic aligns with the circuit's polarity requirements and noise immunity needs.
Part Context
This part belongs to the standard Zener diode family produced by Microchip Technology (formerly Microsemi). It shares the DO-213AA physical form factor with other variants in the series, differing primarily in Zener voltage ratings. The product line serves general-purpose discrete semiconductor applications requiring reliable voltage clamping.
Replacement Considerations
Direct substitutes include the 1N4680B and generic equivalents meeting the 2.2V Zener voltage, 0.5W power dissipation, and DO-213AA package specifications. Verify pinout compatibility and thermal characteristics before substitution.
