The 1.5kW rating at the 10/1000µs pulse shape is the standard TVS power metric — derate this figure for shorter or longer pulse durations per the manufacturer's pulse-derating curve. ## Package and board integration Housed in the DO-201AA (DO-27) axial-lead package, the part is a through-hole device — the leads insert into plated through-holes on the PCB and are wave-soldered or hand-soldered. The axial body sits above the board; the lead spacing and hole diameter follow the standard DO-201 footprint in the IPC-2221 land pattern library. The wide junction temperature margin means the TVS can be placed near hot components (power MOSFETs, regulators) without exceeding its thermal limit, as long as the average power dissipation stays within the derated curve. ## Lifecycle reality and sourcing posture For a BOM line that requires a 50V bidirectional TVS in the DO-201 package, the 1.5KE62C-/54 is a known-quantity replacement candidate. Because it is obsolete, a buyer should qualify an alternate source or a functionally equivalent part from the same or a different family before committing to a production run.","metaTitle":"Vishay 1.5KE62C-E3/54 TransZorb TVS, 1.5kW, 89V Clamp","metaDescription":"1.5KE62C-E3/54 Vishay TransZorb bidirectional TVS, 1500W peak pulse, 50.2V standoff, 89V clamp.
