Single Diodes Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging when sourcing from distributors. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the procurement channel provides valid traceability for the onsemi manufacturing lot. Cross-reference datasheet revisions to confirm electrical parameter consistency across production batches.

Single Diodes Selection Notes

Select this component when a 75 V reverse voltage rating is required rather than higher voltage alternatives like the 1N4448. The DO-35 axial package is appropriate for through-hole mounting where surface area constraints are not critical. Consider the 200 mA current limit for load requirements; higher current needs may require different rectifier types. Verify thermal management capabilities align with the specified junction temperature limits.

Single Diodes Part Context

This part belongs to the standard 1N4454 series of small-signal switching diodes manufactured by onsemi. It serves as a general-purpose semiconductor device widely used in consumer electronics and industrial control systems. The TR suffix denotes a specific bulk packaging format intended for automated assembly processes, distinguishing it from loose or cut-tape variants.
