Clamping voltage and protection window
The 1.5KE480CA-TP: Breakdown occurs at a minimum of 456V, clamping the transient to 658V maximum — this 202V window between standoff and clamp ensures the protected line sees no more than 658V during a surge event. The 2.3A peak pulse current rating at the 10/1000µs waveform defines the energy-handling capability; for shorter transients (8/20µs) the peak current is higher, but the 1500W power rating is the constant limit.
Housed in a DO-201AE axial-lead package, the through-hole mounting suits high-reliability and high-temperature applications where surface-mount solder joints may fatigue under thermal cycling. The bulk packaging means parts are shipped loose in tubes or bags — suitable for hand-insertion or wave-solder assembly, not automated pick-and-place.
