Quantities are lot-specific; availability and pricing confirmed at RFQ. ## 200W peak pulse in a SOD-123F footprint Clamps at 38.9V max with a 5.1A peak pulse current. Reverse standoff voltage of 24V means it starts conducting above a 24V rail — suited for 24V DC buses in industrial or telecom gear where transients ride on the supply. Housed in a SOD-123F surface-mount package. The small footprint suits high-density PCB layouts, but the 200W rating limits it to secondary-side or low-energy transient suppression — not primary mains protection. This covers automotive under-hood, outdoor telecom cabinets, and industrial floor applications where the ambient swings wide.","metaTitle":"SMF24AT1 onsemi Zener TVS – Obsolete, 200W, 24V Standoff","metaDescription":"SMF24AT1 onsemi Zener TVS diode, obsolete status. 200W peak pulse, 24V reverse standoff, SOD-123F package.
