The 45.8A peak pulse current rating tells you the diode can handle a substantial surge without failing short, making it a solid choice for general-purpose transient protection in industrial or telecom supplies. ## Package and mounting — through-hole, axial, hand-solderable Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE24-B is through-hole mount — easy to hand-solder into a prototype board or replace in a repair. The DO-201 footprint is standard; the body is large enough to dissipate the 1500W pulse without overheating the leads. ## Lifecycle reality — obsolete, sourced through independent channels Littelfuse lists the 1.5KE24-B as obsolete. For new designs, consider a current-production 1.5KE series variant with the same standoff voltage; for existing BOM lines, this part is available through independent surplus and broker channels. Because it is obsolete, stock is finite and lot-specific.
