The operating junction temperature range spans -55°C to 175°C, covering industrial and telecom outdoor enclosures where ambient heat and self-heating from repetitive surges must be budgeted together. ## Obsolete — sourcing through independent channels Littelfuse has marked the 1.5KE220C as obsolete. For a BOM line that requires this exact clamping voltage and package, the 1.5KE220C remains orderable against the RFQ.","metaTitle":"Littelfuse 1.5KE220C TVS Diode, 1500W, Bidirectional","metaDescription":"Littelfuse 1.5KE220C bidirectional TVS diode, 1500W peak pulse power, 185V standoff, DO-201 package.
