The 200W peak pulse power rating means it can absorb a single short-duration surge within that envelope — useful for protecting sensitive ICs on a 5V bus from ESD or inductive load dumps.
The wide junction range also covers downhole and outdoor telecom gear where the board sees both extremes.
onsemi has marked the SMF5.0AT1 as obsolete.
Yes, onsemi lists the SMF5.0AT1 as obsolete. It is not recommended for new designs. Existing production runs can be supported through independent surplus channels — quantities are confirmed at RFQ.
