The 'Power Line Protection: No' flag means it is not designed for continuous AC mains clamping — use it on DC buses, not 120/240VAC inputs.","metaTitle":"Vishay 1.5KE47-E3/54 TransZorb TVS, 1500W, 67.8V Clamp","metaDescription":"Obsolete Vishay 1.5KE47-E3/54 1500W unidirectional TVS diode, 38.1V standoff, 67.8V clamp.
