- Designed for through-hole PCB integration
Applications
- Voltage reference circuits
- Overvoltage protection stages
- General-purpose voltage regulation
Procurement Notes
Verify the specific manufacturer designation, as multiple vendors produce this part number. Confirm the package style matches the required footprint and ensure the operating temperature range meets the application's environmental constraints. Check datasheets for exact electrical limits before finalizing component selection.
Selection Notes
Select this component when a 39 V reference is required in a standard axial package. Ensure the circuit design accounts for the 500 mW power limit and the specific test current conditions defined in the official documentation. Verify compatibility with the target assembly process for through-hole technology.
Part Context
This component belongs to the standard 1N47xx series of Zener diodes, widely used for basic voltage regulation tasks. The /TR suffix indicates reel packaging for automated insertion. It serves as a fundamental discrete semiconductor element for maintaining potential levels in electronic systems.
Replacement Considerations
Cross-reference with other manufacturers' 1N4716 variants. Verify that substitute parts match the 39 V nominal voltage, 500 mW power rating, and DO-7 package dimensions to ensure mechanical and electrical interchangeability.
