Clamping at 173 V max with an 8.7 A peak pulse current — the TVS absorbs the surge and holds the downstream components below their voltage rating. The DO-201AA (DO-27) axial package is through-hole — it sits in a drilled PCB hole and solders on the opposite side, common in industrial and telecom board layouts. ## Obsolete — sourcing through independent channels Vishay lists the 1.5KE120C-/54 as Obsolete. No pin-compatible direct replacement from Vishay is published; a functional substitute would require verifying the standoff and clamp voltages match the protection threshold.","metaTitle":"1.5KE120C-E3/54 Vishay TVS, 1500W, 97.2V Standoff","metaDescription":"Vishay 1.5KE120C-E3/54 TransZorb TVS, 1500W peak pulse, 97.2V standoff, 173V clamp.
