The 146V reverse standoff voltage (working voltage) means the TVS draws negligible leakage current below that rail; it starts clamping at a minimum breakdown of 162V and limits the transient to 258V at the rated 5.8A peak pulse current. For a 120V or 144V nominal DC bus in an automotive system, this provides a hard clamp before the downstream silicon sees destructive overvoltage. ## Package and board-fit — DO-201AA axial leaded Housed in a DO-201AA (DO-27) axial-leaded package, the 1.5KE180CHE3/54 is a through-hole device. The axial leads require a 1.3mm diameter hole on a 0.400-inch (10.16mm) lead spacing — a standard footprint for this package class. The 1500W pulse rating assumes the leads are soldered into a PCB with adequate copper area for heat sinking; a free-air or socketed mount derates the peak pulse capability. The wide junction temperature margin means the TVS can absorb repetitive pulses without cumulative thermal damage, as long as the average power dissipation stays within the package's thermal limits. ## Sourcing posture — obsolete, quoted to order Availability is lot-specific and confirmed at the time of RFQ; no factory lead time applies. No official successor order code is listed by Vishay for this specific AEC-Q101 variant. For new designs, a parametric equivalent in the same 1.5KE series (non-automotive grade) or a current-production automotive TVS with a similar standoff voltage and package should be evaluated — the board footprint and hole pattern are standard for the DO-201AA package, so a drop-in replacement is possible if the electrical ratings match.","metaTitle":"1.5KE180CHE3/54 Vishay TVS, 1500W, 146V Standoff, DO-201AA","metaDescription":"Obsolete Vishay 1.5KE180CHE3/54 TransZorb TVS, 1500W peak pulse, 146V standoff, AEC-Q101.
