Rated for 200W peak pulse power, this device absorbs moderate surges on a 12V or 15V rail. The 24.4V clamping ceiling keeps downstream 20V-rated ICs within their absolute maximum during an ESD or inductive-load dump.
Housed in the SOD-123F surface-mount package (supplier device package SOD-123FL), the SMF15AT1 suits automated PCB assembly.
The SMF15AT1 is obsolete. Submit an RFQ for a current quote and lot-specific availability.
No official replacement or pin-compatible equivalent is recorded from onsemi. For new designs, consider a current-production Zener TVS in the same SOD-123F package with a 15V standoff voltage. The functional parameters (200W peak pulse, 24.4V clamping) define the replacement criteria.
