Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix designation against official Microchip documentation to confirm tape-and-reel packaging configuration. Ensure the procurement channel provides valid traceability records required for military-grade components. Confirm compliance with export control regulations associated with defense-standard semiconductor devices before finalizing acquisition.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a stable 0.75 mA regulation is required in space-constrained surface-mount layouts. The DO-213AB package offers a robust alternative to through-hole equivalents while maintaining hermetic integrity. Evaluate thermal dissipation limits relative to the 475 mW rating during circuit design to ensure operation within safe junction temperatures under all expected load conditions.

Current Regulation - Diodes, Transistors Part Context

This part is part of the broader 1N5294 family of current regulator diodes produced by Microchip. Variants such as JANTX1N5294UR and JANTXV1N5294UR-1 share similar electrical characteristics but may differ in quality levels or packaging formats. The -1/TR suffix specifically indicates the reel packaging format for automated assembly processes.

Current Regulation - Diodes, Transistors Replacement Considerations

Direct substitutes include JANTX1N5294UR and JANTXV1N5294UR-1 from Microchip. Cross-manufacturer equivalents must be verified for identical 0.75 mA regulation and 1.2 V limiting voltage parameters.
