Breakdown occurs at 570 V minimum, so the diode starts conducting well before the clamp voltage is reached. This gives a guard band for leakage current — the part stays below 1.8 A peak pulse current at the clamping point. ## Board-fit and environment Housed in a DO-201AA axial-lead package (also known as DO-27), the 1.5KE600CA mounts through-hole. The large body and lead diameter handle the thermal pulse of a 1.5 kW surge without lifting the trace — keep the lead bends short and the hole diameter to the recommended 1.1 mm for reliable solder fill.","metaTitle":"1.5KE600CA Littelfuse TVS Diode, 1.5kW, 512V Standoff","metaDescription":"Active 1.5KE600CA Littelfuse bidirectional TVS diode, 1500W peak pulse, 512V standoff, DO-201.
