Breakdown occurs at 14.3 V minimum, meaning the protection threshold sits comfortably above the rail tolerance but below the downstream component's absolute maximum. ## Package and temperature range — board-fit and environment Housed in a DO-201AA / DO-27 axial leaded package, it mounts through-hole on a standard 0.100-inch pitch footprint. The operating junction temperature range spans -55°C to 175°C, covering industrial enclosures and under-hood automotive compartments without derating concerns. The TransZorb series is Vishay's branded TVS line; this part carries the base product number 1.5KE15, which is shared across multiple package and polarity variants for BOM consolidation.","metaTitle":"1.5KE15CA-E3/73 Vishay TVS Diode, 1.5 kW, Bidirectional","metaDescription":"1.5KE15CA-E3/73 Vishay TransZorb TVS diode, 1.5 kW peak pulse, 12.8 V standoff, bidirectional, DO-201AA axial.
