1N5295

Overview

The 1N5295 is a silicon current regulator diode manufactured by Microchip Technology. It provides a constant current output of 902 µA with a maximum voltage rating of 100 V and a power dissipation capacity of 500 mW. The device features a limit voltage of 1.25 V and operates within a junction temperature range of -65°C to 175°C. It is housed in an axial DO-7 (DO-204AA) package designed for through-hole mounting.

Feature Summary

• Maintains stable current regulation across varying load conditions
• Operates reliably at elevated junction temperatures up to 175°C
• Utilizes standard axial leaded packaging for through-hole integration

Applications

• Biasing circuits for transistors and integrated circuits
• Constant current sources for LED drivers
• Current limiting protection in electronic circuits

Procurement Notes

Verify the specific suffix against official Microchip documentation, as variants such as 1N5295-1 exist with identical electrical characteristics but potentially different packaging or qualification standards. Confirm RoHS compliance status directly from the manufacturer datasheet prior to procurement, as regulatory markings vary by production batch and region.

Selection Notes

Select this component when a fixed low-current source near 1 mA is required without active feedback loops. Ensure the circuit voltage does not exceed the 100 V maximum rating. Consider thermal management for the 500 mW dissipation limit in enclosed environments. Verify that the axial DO-7 package fits the available PCB real estate.

Part Context

This part belongs to the 1N52xx series of current regulator diodes produced by Microchip Technology. These devices are legacy components often used in industrial and military applications requiring simple, robust current control. The series covers various current levels from microamperes to milliamperes, sharing similar internal structures and packaging options.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Equivalent functionality may be found in other manufacturers' current regulator diode series, but direct pin-for-pin replacement requires verification of electrical tolerances and package dimensions.
