The 43.5 V clamping voltage at 34.5 A peak pulse current defines the maximum voltage the downstream circuitry sees during a surge event — a figure to check against the absolute-max ratings of the powered devices on that rail. ## Obsolete — sourcing through independent channels Vishay lists this part as Obsolete. ## Temperature range and package fit Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE30-/54 mounts through hole and suits point-to-point wiring or PCB layouts where the axial body is soldered into plated holes.","metaTitle":"1.5KE30-E3/54 Vishay TVS, 1500W, 24.3V Standoff, DO-201","metaDescription":"Vishay 1.5KE30-E3/54 TransZorb TVS, 1500W peak pulse, 24.3V reverse standoff, DO-201 axial.
