Overview
The 1N4692UR-1 is a silicon unidirectional Zener diode manufactured by Microchip Technology. It features a nominal Zener voltage of 6.8V with a tolerance of 5% and a maximum power dissipation of 0.5W. The component utilizes a DO-213AA package, also identified as MELF-2, constructed from hermetically sealed glass. It contains a single diode element with two terminals and an isolated case connection.
Feature Summary
- Hermetically sealed glass construction for environmental protection
- Unidirectional Zener voltage regulation capability
- Single-element silicon diode configuration
Applications
- Voltage reference circuits
- Overvoltage protection
- Clamping applications
Procurement Notes
Verify the specific manufacturer documentation to confirm compliance with current environmental directives such as RoHS, as historical data indicates mixed status within this product family. Ensure the ordering suffix matches the required hermetic sealing specifications. Cross-reference the DO-213AA package dimensions against the target PCB layout requirements before finalizing procurement decisions.
Selection Notes
Select this component when a hermetically sealed Zener diode is required for high-reliability environments. The 6.8V nominal voltage and 0.5W power rating define its operational limits. Consider the MELF-2 package form factor for surface-mount integration where space constraints exist but hermeticity remains a critical design parameter.
Part Context
This part belongs to the 1N469x series of Zener diodes produced by Microchip Technology. The 'UR' suffix typically denotes a specific packaging or processing variant within the company's discrete semiconductor portfolio. These components are designed for general-purpose voltage regulation tasks requiring stable performance over temperature variations.
Replacement Considerations
Direct substitutes include other hermetically sealed Zener diodes in the DO-213AA/MELF-2 package with matching 6.8V and 0.5W ratings. Verify pinout compatibility and thermal characteristics before substitution.
