No pin-compatible direct replacement from Vishay is documented; a parametric search on 1500 W, 97.2 V standoff, and DO-201AA package will identify functionally similar TVS diodes from other manufacturers if a board spin is acceptable.","metaTitle":"Vishay 1.5KE120-E3/73 TransZorb TVS, 1500W, 173V Clamp","metaDescription":"Vishay 1.5KE120-E3/73 TransZorb Zener TVS diode, 1500W peak pulse, 173V clamping, DO-201AA.
