A 97.2V standoff means the diode draws negligible leakage below that voltage; the 108V minimum breakdown ensures it starts conducting before the protected circuit's 120V rail exceeds its rating.","metaTitle":"1.5KE120HE3/54 Vishay TVS, 1500W, 108V Breakdown, DO-201AA","metaDescription":"Vishay 1.5KE120HE3/54 obsolete TVS diode, 1500W peak pulse, 108V min breakdown, AEC-Q101.
