The 1.5KE120HE3/54: The 1500W peak pulse rating (10/1000µs) defines the energy-handling capability for a single surge event — at the clamping voltage of 173V, the diode absorbs 8.7A peak without failing short. 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.
