• Capable of operating in extreme temperature conditions up to 175°C
• Utilizes compact surface-mount packaging for space-constrained designs

Applications

• Biasing transistors and integrated circuits
• LED current limiting and regulation
• Constant current sources for sensor interfaces

Procurement Notes

Verify the specific suffix '-1' against official Microchip documentation to confirm if it denotes a military or enhanced specification variant compared to the standard 1N5299. Ensure compatibility with RoHS directives if required by your project specifications. Confirm availability through authorized distributors as lead times may vary for specialized variants.

Selection Notes

Select this component when a fixed current source is required within a 1.32mA tolerance. Ensure the circuit voltage does not exceed the 100V maximum rating. Consider the thermal management requirements given the 475mW power dissipation limit. Verify that the SOD-80 footprint matches the PCB layout constraints.

Part Context

This part belongs to the 1N52xx series of current regulator diodes manufactured by Microchip Technology. These devices are widely used in analog and mixed-signal applications where precise current control is necessary. The series offers various current values to suit different design needs, with the 1N5299 providing a specific 1.32mA output.

Replacement Considerations

Check for direct substitutes such as the standard 1N5299 if the '-1' suffix does not indicate a critical functional difference. Other manufacturers offer equivalent current regulator diodes; verify pinout compatibility and electrical parameters before substitution.
