Overview
The 1N5295/TR is a current regulator diode manufactured by Microchip Technology, designed for through-hole mounting in the DO-7-2 package. It operates within an extended temperature range from -55°C to +175°C and features a maximum peak working voltage of 100 V. The device provides a maximum regulator current of 902 µA with a power dissipation rating of 475 mW. Key electrical characteristics include a maximum limit voltage of 1.25 V and a minimum dynamic impedance of 1 MΩ. This single-configuration component is part of the Microchip/Microsemi product line.
Feature Summary
- Maintains stable current regulation across wide operating conditions
- Supports high-temperature environments up to 175°C
- Provides high dynamic impedance for effective current limiting
Applications
- Constant current sources for LED driving
- Biasing circuits for semiconductor devices
- Current limiting protection in sensitive electronic systems
Procurement Notes
Verify the specific suffix /TR indicates reel packaging configuration when sourcing. Confirm RoHS status as non-compliant based on available data. Ensure the DO-7-2 through-hole package matches the target PCB footprint requirements before integration into the design.
Selection Notes
Select this component when a fixed current source near 902 µA is required with high voltage tolerance. The DO-7-2 package suits through-hole assembly processes. Consider the 1 MΩ dynamic impedance for applications demanding minimal current variation under changing load conditions.
Part Context
This part belongs to the 1N52xx series of current regulator diodes produced by Microchip Technology. It shares functional similarities with other parts in the series but is distinguished by its specific 902 µA current rating and 100 V peak voltage capability, tailored for robust industrial or military-grade applications.
Replacement Considerations
Direct substitutes include other 1N5295 variants such as 1N5295UR-1, though packaging differences exist. Verify equivalent current ratings and package compatibility when cross-referencing with generic current regulator diodes from other manufacturers.
