In a 400 VAC three-phase rectified bus, the DC rail sits around 565 V, which exceeds the 408 V standoff; this part is better suited for single-phase 240 VAC or 277 VAC lines where the DC bus stays under 400 V. ## Through-hole DO-201 package and thermal reach The DO-201AA (DO-27) axial-lead package is a through-hole form factor with a large copper slug inside the epoxy body that spreads heat from the junction to the leads. Because it is a single unidirectional channel, the cathode band must face the positive rail. Power line protection is marked as 'No' in the spec — this is a data-line or DC-bus TVS, not a mains AC line protector. The tape-and-reel or cut-tape packaging options suit both prototype hand-assembly and production wave-solder runs. ## Active production and sourcing posture The DO-201 package is common across the 1.5KE series, so a reel or cut-tape quantity is straightforward to procure.","metaTitle":"Littelfuse 1.5KE480A TVS Diode, 1500W, 658V Clamp","metaDescription":"Littelfuse 1.5KE480A Zener TVS diode, 1500W peak pulse power, 408V standoff, 658V clamp.
