JANS1N5283-1/TR is listed in the Current Regulation - Diodes, Transistors range at ChipApex. The manufacturer field lists Microchip Technology. Its product description is DIODE CUR REG 100V 242UA 500MW. Review the specifications below when checking this part for your BOM.
The JANS1N5283-1/TR is a silicon current regulator diode manufactured by Microchip Technology. It provides a regulated current of 242 µA with a maximum limit voltage of 1 V and a peak operating voltage of 100 V. The device is housed in a DO-7-2 through-hole package and operates within a temperature range of -65 °C to +175 °C. It features a minimum dynamic impedance of 25 mΩ and a knee impedance of 2.75 mΩ, designed for high-reliability applications.
Verify the JANS suffix indicates specific military-grade screening and radiation tolerance requirements. Confirm the /TR suffix denotes tape and reel packaging configuration. Ensure compliance with MIL-PRF-19500 standards if required by the system specification. Validate that the DO-7-2 package meets mechanical constraints.
Select this component when radiation-hardened constant current sources are necessary. Compare against JAN or commercial variants if environmental shielding is present. Verify that the 242 µA output current aligns with circuit biasing needs. Check thermal management requirements given the 175 °C maximum junction temperature rating.
This part belongs to the 1N5283 series of current regulator diodes produced by Microchip Technology. It shares electrical characteristics with other members like the JAN1N5283-1 but includes additional screening for harsh environments. The series offers various current ratings and packaging options for different industrial and defense applications.
Publicly confirmed substitute part numbers are not available in the provided documentation.
