The bidirectional structure means a single device guards both polarities on the same line — no need for series back-to-back arrangements. The DO-201AE axial package (through-hole) handles the thermal pulse of a 1.5 kW surge without lifting a pad, provided the lead length and PCB copper area follow the derating guidelines for repetitive events. The operating junction temperature range spans -55°C to 175°C — a full military-temperature-class envelope. That 175°C ceiling means the part can sit next to a hot power resistor or in an engine-bay ECU without derating the peak pulse power at elevated ambient, though the 1.5 kW rating is specified at 25°C and derates linearly above that. For a 85°C ambient, budget roughly 75% of the rated power. Power line protection is marked as 'No' — this is a signal- or low-power-rail suppressor, not a mains-side MOV replacement. Use it on DC buses, communication lines, or sensor outputs where the transient energy stays within the 1.5 kW envelope. ## Active production — sourcing posture The part is available in Tape & Reel (TR) or Cut Tape (CT) packaging for the DO-201AE axial format, which suits both automated insertion and small-run rework.","metaTitle":"Micro Commercial Co 1.5KE47CA-TP TVS Diode, 1500W, 40.2V","metaDescription":"Active 1500W bidirectional TVS diode from Micro Commercial Co. 40.2V standoff, 44.7V breakdown, 64.8V clamping.
