1N5288 TR PBFREE

Overview

The 1N5288 TR PBFREE is a silicon field-effect current regulator diode manufactured by Central Semiconductor Corp. It provides steady-state current regulation with a specified knee current of 0.39mA and a maximum limiting voltage of 1.05V. The device operates within a temperature range of -65°C to 200°C and features a DO-35 axial glass package. It is hermetically sealed, isolated, and designed for high-reliability applications.

Feature Summary

• Provides constant current regulation using silicon field-effect technology
• Hermetically sealed in a DO-35 glass package for environmental protection
• Isolated case connection for flexible circuit integration
• Rated for extended operating temperatures up to 200°C

Applications

• LED driver circuits requiring stable current control
• High-reliability electronic systems demanding consistent current flow
• Circuit elements for peak operating voltage stabilization

Procurement Notes

Verify the specific datasheet version for the 1N5288 TR PBFREE variant to confirm compliance with RoHS directives, as some historical records indicate non-compliance. Ensure the procurement order specifies the tape-and-reel packaging format corresponding to the 'TR' suffix. Cross-reference the manufacturer's official documentation to validate the hermetic sealing status and isolation characteristics required for your specific application environment.

Selection Notes

Select this component when a fixed current output near 0.39mA is required without complex biasing networks. The wide temperature range supports operation in harsh environments where standard diodes might fail. Consider the DO-35 package dimensions for PCB layout constraints. Verify that the 1.05V limiting voltage aligns with the downstream circuit requirements to prevent overvoltage conditions during regulation.

Part Context

This part belongs to the 1N5283 series of silicon field-effect current regulator diodes produced by Central Semiconductor. These devices are engineered to maintain a constant current over a wide range of voltages. The series is characterized by high reliability and stability, making it suitable for critical applications where current consistency is paramount for system performance and longevity.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with generic equivalents based on the 0.39mA current rating and DO-35 package specifications before substitution.
