JANTXV1N5287-1

Current Regulation - Diodes, Transistors Overview

The JANTXV1N5287-1 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. The device provides a regulated current of 363 µA with a maximum anode-to-cathode voltage of 100 V and a power dissipation rating 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 is designed for high reliability in military and aerospace applications.

• High-reliability analog signal conditioning circuits

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix JANTXV against the official Microchip datasheet to confirm the exact tolerance and qualification level required for your design. Ensure the ordering documentation explicitly references MIL-PRF-19500/463 compliance. Confirm that the DO-7 axial leaded package matches your PCB footprint requirements before finalizing procurement orders.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a precise constant current source is needed rather than voltage regulation. Compare the 363 µA output against circuit requirements to ensure compatibility with downstream loads. Consider the 100 V maximum voltage rating to guarantee operation within safe limits during transient conditions or open-circuit scenarios.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 W current regulators. The series offers various current values ranging from 0.22 mA to 4.7 mA. The JANTXV1N5287-1 specifically represents the higher reliability JANTXV grade within this family, distinguished by its specific 363 µA regulation point.

Current Regulation - Diodes, Transistors Replacement Considerations

Commercial equivalents such as the standard 1N5287 may be considered if military qualification is not required. Verify that substitute parts maintain the same 363 µA regulation current and 100 V breakdown voltage. Ensure any replacement also utilizes the DO-7 axial package for mechanical compatibility.
