Breakdown starts at 50.4 V minimum, and the clamping voltage at peak pulse current (18.6 A) is 80.5 V maximum, which defines the voltage the downstream components must survive during a transient. ## Obsolete — sourcing through independent channels Vishay has marked the 1.5KE56CHE3/54 as obsolete. Available through independent distribution against an RFQ — lot traceability and date codes confirmed at quote time.
