JANTX1N5307UR-1/TR

Current Regulation - Diodes, Transistors Overview

The JANTX1N5307UR-1/TR is a current regulator diode manufactured by Microchip Technology, designed for surface-mount applications. It operates within the MIL-PRF-19500/463 military series and utilizes a DO-213AB (MELF) glass package. The device provides a maximum regulated current of 2.64 mA with a peak working voltage of 100 V and a power dissipation rating of 500 mW. It supports through-hole equivalent performance in an SMT form factor, functioning as a stable current source across a junction temperature range of -65°C to +175°C.

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix configuration when ordering, as the /TR designation indicates tape and reel packaging which differs from bulk options. Confirm that the JANTX grade meets the required radiation hardness and reliability standards for the intended aerospace or defense application before finalizing procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a surface-mount solution is required for a circuit originally designed around the axial 1N5307 family. Ensure the PCB layout accommodates the DO-213AB footprint and that the thermal management strategy supports the 500 mW dissipation limit at elevated ambient temperatures up to 175°C.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5307 family of current regulator diodes produced by Microchip's Microsemi division. It serves as the surface-mount variant of the traditional axial leaded components, offering identical electrical characteristics in a compact MELF package suitable for high-density mounting.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct functional equivalents include the standard 1N5307 for through-hole designs. For surface-mount replacements, verify compatibility with other manufacturers' DO-213AB current regulator diodes having matching 2.64 mA regulation and 100 V breakdown ratings.
