Procurement Notes
Verify the specific suffix E3/TR against official Microchip documentation to confirm RoHS compliance and tape-and-reel packaging details. Ensure compatibility with existing PCB footprints for the DO-7 axial package. Cross-reference datasheet parameters such as voltage tolerance and leakage current to validate suitability for the intended circuit design before procurement.
Selection Notes
Select this component when a fixed current of 1.32 mA is required with a maximum voltage drop of 100 V. Consider the 475 mW power dissipation limit and the -55°C to 175°C operating range for environmental constraints. Compare with other 1N52xx series variants if different current levels or package types are needed for the specific application requirements.
Part Context
The 1N5299E3/TR belongs to the 1N5283-1N5314 series of current regulator diodes manufactured by Microchip Technology. These devices are part of a broader family of discrete semiconductor components designed for reliable current control in analog and digital circuits. The series offers various current ratings to suit different design needs while maintaining consistent performance characteristics across the product line.
Replacement Considerations
Consult the official 1N5283-1N5314 datasheet for confirmed substitute part numbers. Verify that any alternative component matches the 1.32 mA current rating, 100 V maximum voltage, and DO-7 package dimensions to ensure direct interchangeability without circuit modification.
