At the full 1500 W pulse, the clamp voltage holds at 104 V — the downstream components must survive that peak without avalanche breakdown. The 14.6 A peak pulse current rating at 10/1000 µs defines the surge the part absorbs before the clamp voltage rises above 104 V. A longer or higher-energy pulse pushes the junction temperature past 175 °C and risks failure — the 1500 W rating assumes the pulse width and waveform stay within the standard TVS test condition. ## Through-hole axial package for board-level protection Housed in a DO-201AA (DO-27) axial leaded package, this TVS mounts through-hole on a PCB or terminal block. The axial body handles the thermal stress of a 1500 W pulse by conducting heat into the leads and the copper trace area — the board copper under each lead acts as the primary heatsink. ## Last-buy status and sourcing posture Vishay has placed the 1.5KE75A-/51 on last-buy status — the manufacturer no longer accepts new orders beyond the final buy window.","metaTitle":"Vishay 1.5KE75A-E3/51 TransZorb TVS, 1500W, 104V Clamp","metaDescription":"Vishay 1.5KE75A-E3/51 TransZorb unidirectional TVS, 1500W peak pulse, 104V clamp, DO-201AA.
