1N5290 TR PBFREE

Overview

The 1N5290 TR PBFREE is a silicon field-effect current regulator diode manufactured by Central Semiconductor Corp. It provides constant current regulation with a maximum regulator current of 517 uA and a maximum peak operating voltage of 100 V. The device features a maximum limiting voltage of 1.05 V and a power dissipation rating of 600 mW. This component is designed to regulate current over a broad operating voltage and temperature range, utilizing a double-plug construction for enhanced reliability.

Feature Summary

• Regulates current over a broad operating voltage and temperature range
• Utilizes double-plug construction for structural integrity
• Designed as a silicon field effect current regulator diode

Applications

• Constant current source applications
• Biasing circuits requiring stable current levels
• Current limiting protection in electronic systems

Procurement Notes

Verify the specific ordering suffix 'TR PBFREE' ensures RoHS compliance and tape-and-reel packaging format when sourcing from distributors. Confirm that the manufacturer designation aligns with Central Semiconductor Corp specifications, noting that some listings may reference Microchip Technology as a distributor or historical entity. Ensure the part number matches the exact electrical parameters required for your design constraints.

Selection Notes

Select this component when a fixed current output near 517 uA is required within a 100 V limit. Consider the 600 mW power dissipation capability for thermal management. Evaluate the double-plug construction benefits if mechanical stability is critical. Compare against other current regulator diodes if different current thresholds or package types are needed for the specific application environment.
