JANTX1N5287-1/TR

Current Regulation - Diodes, Transistors Overview

The JANTX1N5287-1/TR is a current regulator diode from the MIL-PRF-19500/463 qualified series, manufactured by Microchip Technology. It operates in a through-hole DO-7 (DO-204AA) axial package and is supplied in tape-and-reel packaging. The device provides a regulated current of 363 µA with a maximum anode-to-cathode voltage rating of 100 V and a power dissipation capacity of 500 mW. It functions as a constant current source over a broad voltage range, serving as a counterpart to Zener diodes which regulate voltage. The component supports junction temperatures from -65°C to +175°C.

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix designation when ordering, as the standard datasheet lists bulk packaging while the requested model indicates tape-and-reel configuration. Confirm that the JANTX grade meets the required environmental and reliability standards for the intended military or industrial application before finalizing procurement.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a fixed current sink is required independent of voltage fluctuations within the specified limits. Ensure the load voltage does not exceed the 100 V maximum rating and that the thermal design accommodates the 500 mW power dissipation at the highest expected ambient temperature.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the popular 1N5283-1 through 1N5314-1 series of 0.5-watt current regulators. These devices offer a selection of currents ranging from 0.22 mA to 4.7 mA in standard tolerances.
