Overview
The Microchip Technology 1N5284-1 is a current regulator diode designed for stable current control in electronic circuits. It features a maximum voltage of 100V and a regulated current of 264µA. The device supports a power dissipation of 500mW and operates within a temperature range of -65°C to 175°C. Packaged in the DO-204AA axial leaded format, it provides reliable performance for precision applications requiring constant current sources.
Feature Summary
- Maintains constant current output across varying load conditions
- Operates reliably in extreme high and low temperature environments
- Provides simple two-terminal current regulation without complex biasing
Applications
- Precision current limiting in sensor interfaces
- Biasing elements for LED drivers
- Constant current sources for analog signal conditioning
Procurement Notes
Verify the specific suffix designation against official Microchip documentation to confirm package type and electrical tolerances. Ensure compatibility with existing thermal management designs due to the specified power dissipation limits. Confirm RoHS compliance status as required by project specifications before finalizing procurement orders.
Selection Notes
Select this component when a fixed current value near 264µA is required with high voltage tolerance. Consider the axial package constraints for PCB layout compared to surface mount alternatives. Evaluate thermal requirements to ensure the 500mW rating is sufficient for the intended operating environment and duty cycle.
Part Context
This part belongs to the 1N528x series of current regulator diodes manufactured by Microchip Technology. It shares functional similarities with other devices in the family but offers specific current and voltage characteristics tailored for distinct circuit requirements. The series is widely used in industrial and aerospace applications demanding high reliability.
Replacement Considerations
Direct substitutes include the JAN1N5284UR-1 for surface mount variants or the CD5284 for reel-packaged versions. Verify pinout compatibility and thermal resistance values when transitioning between different package styles to ensure proper circuit integration.
