The device features a maximum peak working voltage of 100V and a power dissipation rating of 600mW. It supports a wide operating temperature range from -65°C to +200°C, ensuring durability in demanding environments. The component is supplied in tape and reel packaging for automated assembly processes.

Feature Summary

• Maintains constant current flow for circuit stability
• Supports high-temperature operation up to 200°C
• Designed for through-hole mounting via DO-35 package

Applications

• Constant current source generation
• Biasing circuits for transistors and LEDs
• Current limiting protection in sensitive electronics

Procurement Notes

Verify the specific ordering suffix RL indicates tape and reel packaging configuration. Confirm RoHS compliance status with the manufacturer prior to procurement, as non-RoHS variants may exist within the same part family. Ensure the supplier provides official datasheets matching the exact part number to avoid discrepancies in electrical characteristics or package dimensions during integration.

Selection Notes

Select this component when a fixed current regulation solution is required without active feedback loops. Consider the DO-35 package constraints for PCB layout and thermal management. Evaluate the maximum junction temperature limits against the expected ambient conditions to ensure long-term reliability. Compare dynamic impedance specifications if precise current stability under varying voltage conditions is critical for the application design.

Part Context

The 1N5298RL belongs to the broader 1N5298 series of current regulator diodes manufactured by Microchip Technology. This series utilizes standard DO-35 axial leaded packages suitable for general-purpose electronic assemblies. The RL suffix specifically denotes the reel-based packaging format, distinguishing it from bulk or single-unit configurations available within the same functional family.

Replacement Considerations

Cross-reference with other manufacturers' 1N5298 equivalents such as Central Semiconductor versions. Verify pin compatibility and electrical parameter tolerances before substitution. Ensure the replacement part meets the same thermal and voltage ratings to maintain circuit integrity.
