Overview
The Microchip Technology 1N5288-1 is a current regulator diode designed for stable current control in electronic circuits. It features a maximum anode-to-cathode voltage of 100V and a regulated current of 429µA. The device has a maximum power dissipation of 500mW and a maximum limiting voltage of 1.05V. It operates within a junction temperature range of -65°C to 175°C. The component utilizes a DO-204AA (DO-7) axial leaded package suitable for through-hole mounting.
Feature Summary
- Provides constant current regulation with specified tolerance
- Capable of withstanding high peak operating voltages up to 100V
- Supports extended thermal operation up to 175°C junction temperature
Applications
- Biasing circuits requiring stable low-current sources
- Protection against overcurrent conditions in sensitive loads
- Current limiting in LED driver configurations
Procurement Notes
Verify RoHS compliance status as the product is listed as non-compliant. Confirm the specific manufacturing date code and assembly site details via the latest PCN documentation before integration. Ensure the DO-7 axial package matches the target PCB footprint requirements for through-hole assembly processes.
Selection Notes
Select this component when a fixed current of approximately 429µA is required without active feedback loops. Compare against similar models like the 1N5283 if different current levels are needed. Verify that the 500mW power rating suffices for the expected voltage drop across the device in the specific application environment.
Part Context
The 1N5288-1 belongs to the 1N5288 series of current regulator diodes manufactured by Microchip Technology. This series offers various current options within the same package family, allowing designers to choose precise current values while maintaining consistent physical dimensions and thermal characteristics for board layout standardization.
Replacement Considerations
Check the 1N5283 datasheet for alternative current regulation needs. Verify pinout compatibility and thermal resistance parameters before substituting with other manufacturers' equivalents to ensure circuit stability.
