For a 342 V standoff rail, the TVS remains transparent under normal operation and only conducts when the transient exceeds the 380 V breakdown threshold. The 1500 W peak pulse rating is the device's energy-handling capability for the standard 10/1000 µs waveform — a key parameter for sizing protection in automotive load-dump or inductive kickback scenarios. ## Automotive qualification and compliance The series is also RoHS-compliant and supplied in tape-and-reel packaging for automated assembly. ## Obsolete — sourcing through independent channels Vishay has marked the 1.5KE400A-804E3/54 as obsolete. No official successor order code is recorded. For new designs, a functionally equivalent TVS with the same standoff voltage and package should be selected from Vishay's current TransZorb portfolio.","metaTitle":"Vishay 1.5KE400A-804E3/54 TransZorb TVS, 1.5 kW, 548V Clamp","metaDescription":"Vishay 1.5KE400A-804E3/54 automotive AEC-Q101 TransZorb TVS diode, 1500W peak pulse, 342V standoff, 548V clamp.
