The 725 V clamp at 2.1 A peak pulse current means the protected rail sees no more than 725 V during a surge — the margin above the 451 V standoff determines how much overvoltage the downstream equipment must survive. The single unidirectional channel handles one polarity of transient; for AC or bidirectional lines, two devices back-to-back or a dedicated bidirectional TVS would be needed. ## Package and temperature range Housed in the DO-201AA (DO-27) axial-lead package, it mounts through hole — the leads are formed for through-board insertion, and the body is suited for point-to-point wiring or PCB mounting with lead bending.","metaTitle":"Littelfuse 1.5KE530A Zener TVS, 1500W, 451V Standoff, DO-201","metaDescription":"Littelfuse 1.5KE530A Zener TVS diode, 1500W peak pulse, 451V reverse standoff, 725V clamp.
