It clamps transients at 33.2V maximum while conducting 45A peak pulse current, protecting downstream circuitry from surges on a 20.5V nominal rail. Housed in an axial-lead package, it is a through-hole part suited for board-level transient suppression in general-purpose industrial and telecom equipment. ## Obsolete — Plan Your Last-Time Buy or Replacement onsemi has marked the 1.5KE24AG as Obsolete. For new designs or BOM continuity, a functionally equivalent Zener TVS in the same 1.5KE family (e.g., 1.5KE24A) or a different series with matching 20.5V standoff and 1500W rating should be evaluated. ## Parametric Fit for the 20.5V Rail The 20.5V reverse standoff voltage sets the maximum continuous DC voltage the diode can tolerate without conducting. Breakdown occurs at 22.8V minimum, and clamping is guaranteed at 33.2V with a 45A peak pulse current. This leaves a 12.7V window between the rail and the clamp — adequate for protecting 24V nominal supplies against inductive spikes or lightning-coupled surges. ## Sourcing the 1.5KE24AG Today Because the 1.5KE24AG is obsolete, standard distributor stock is depleted. We source this part per RFQ from our supply network — confirm quantity and lead time at quote. No stock-holding claim is made.","metaTitle":"1.5KE24AG onsemi Zener TVS Diode 1500W DO-201AD Obsolete","metaDescription":"onsemi 1.5KE24AG Mosorb™ Zener TVS, 1500W peak pulse, 20.5V standoff, 33.2V clamp.
