JANTX1N5297-1

Current Regulation - Diodes, Transistors Overview

The JANTX1N5297-1 is a silicon current regulator diode from the 1N5283-1 through 1N5314-1 series, manufactured by Microchip Technology. It operates in a DO-7 (DO-204AA) axial-leaded package with through-hole mounting. The device provides a regulated current of 1 mA with a standard tolerance of 10%. 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 qualified under MIL-PRF-19500/463 for military applications and features a double-plug internal bond connection within its larger DO-7 packaging.

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific revision level and manufacturer lot traceability when sourcing this component. Ensure that the procurement channel provides documentation confirming compliance with MIL-PRF-19500/463 specifications. Confirm that the physical package matches the DO-7 axial leaded form factor required for the intended PCB layout or chassis mounting application.

Current Regulation - Diodes, Transistors Selection Notes

Select this device when a fixed current sink is required independent of supply voltage fluctuations within the breakdown region. Compare against the commercial 1N5297 variant if military qualification is unnecessary. Consider the JANTXV1N5297-1 if tighter tolerance specifications are required beyond the standard 10% rating provided by the JANTX grade.

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. They are designed to complement Zener diodes by regulating current rather than voltage, utilizing similar size axial-leaded packages for ease of integration into existing circuit designs.
