This is the voltage the protected circuit must survive — a 138V bus sees a transient clamped to 244V, which is within the typical 250V-300V MOSFET breakdown range for 150V-rated DC-DC converters. ## Obsolete — sourcing through independent channels Stock is sourced through independent surplus and broker distribution. Each lot is verified for traceability and authenticity before quoting.","metaTitle":"1.5KE170CHE3/73 TVS, 1500W, 138V Standoff, DO-201AA","metaDescription":"Obsolete Vishay 1.5KE170CHE3/73 TransZorb TVS, 1500W peak pulse, 138V standoff, 244V clamp, AEC-Q101.
