1N5295-1/TR

Overview

The 1N5295-1/TR is a current regulator diode manufactured by Microchip Technology, designed for stable current regulation in electronic circuits. It features a maximum regulator current of 902 µA and a maximum limit voltage of 1.25 V. The device supports a peak operating voltage of 100 V and has a power dissipation rating of 500 mW. It operates within a temperature range of -55 °C to +175 °C junction temperature. The component utilizes a DO-7 (DO-204AA) axial through-hole package and is supplied in tape and reel packaging.

Feature Summary

• Provides constant current regulation with a specified maximum current of 902 µA
• Capable of withstanding high reverse voltages up to 100 V peak operating voltage
• Engineered for extended thermal stability across a wide junction temperature range from -55 °C to +175 °C
• Constructed using silicon technology for reliable performance in harsh environments

Applications

• Biasing circuits for transistors and other semiconductor devices requiring stable current sources
• Protection circuits where constant current limiting is necessary to prevent component damage
• Industrial control systems operating under extreme temperature conditions
• Military and aerospace electronics demanding high reliability and wide thermal tolerance

Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging configuration, as standard variants may differ. Ensure that the procurement channel provides authentic Microchip Technology components to guarantee compliance with military-grade specifications. Cross-reference the manufacturer part number with official datasheets to validate electrical parameters before integration into design projects.

Selection Notes

Select this component when a precise current regulation value near 902 µA is required alongside high voltage tolerance. Consider the DO-7 through-hole package constraints for PCB layout and mechanical mounting requirements. Evaluate the thermal management needs given the 500 mW power dissipation capability and the wide operating temperature range suitable for demanding industrial or defense applications.

Part Context

This part belongs to the 1N5295 series of current regulator diodes produced by Microchip Technology, encompassing both Microsemi and Microchip brands. The series offers various current regulation values tailored for different circuit requirements. The 1N5295-1 variant specifically targets applications needing higher current regulation compared to lower-current counterparts in the same family.

Replacement Considerations

Direct substitutes include the 1N5295-1 without the trailing slash TR if bulk packaging is acceptable. Other parts in the 1N5295 series may serve as alternatives if current regulation values can be adjusted via external circuitry. Verify pinout compatibility and thermal characteristics when considering cross-brand replacements.
