The minimum breakdown voltage of 380 V ensures the device does not conduct during normal operation, while the 548 V clamp limits the transient to a level that downstream semiconductors rated for 600 V can survive. ## Obsolete — sourced through surplus channels Vishay has marked the 1.5KE400CA-/51 as obsolete. Each lot is sourced and verified against the original Vishay specifications; quantities and pricing are confirmed at RFQ time.","metaTitle":"Vishay 1.5KE400CA-E3/51 TransZorb TVS, 1500W, 342V Standoff","metaDescription":"Obsolete Vishay 1.5KE400CA-E3/51 bidirectional TVS diode, 1500W peak pulse, 342V reverse standoff, DO-201AA.
