The 1500W peak pulse rating at 25°C derates linearly with ambient temperature — at 175°C the power capability drops to roughly 25% of the 25°C value, so the actual surge current the part can absorb depends on the operating temperature profile. The DO-201AA axial package (also known as DO-27) allows through-hole mounting on a PCB or terminal block, with the lead bend forming the thermal path to the board copper. No power line protection feature is integrated — this is a pure transient suppressor, not a filter or regulator.","metaTitle":"1.5KE51AHE3_B/C Vishay TVS, 1500W, 43.6V Standoff, DO-201","metaDescription":"Active Vishay TransZorb® TVS diode, 1500W peak pulse, 43.6V standoff, AEC-Q101 automotive grade.
