Procurement Notes
Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm that the D-5D-2 package matches the target footprint. Ensure procurement channels are authorized to guarantee component authenticity and traceability for aerospace or military specifications.
Selection Notes
Select this component for designs requiring hermetic sealing and radiation tolerance. Compare the 100 mA forward current against circuit requirements. Verify thermal management needs given the operating temperature range. Consider the 5 ns recovery time for high-speed switching constraints.
Part Context
This part belongs to the 1N6642 series of switching diodes manufactured by Microchip Technology. It shares core electrical characteristics with through-hole variants but utilizes a surface mount package. The series is characterized for total ionizing dose performance, supporting reliability in demanding operational environments.
Replacement Considerations
JAN1N6642U/TR offers equivalent electrical specifications in a similar surface mount format. JANTX1N6642UBCC/TR provides dual configuration options within the same family. Verify pinout compatibility before substituting.
