The -55°C to 175°C operating junction range covers under-hood and engine-bay environments where a standard commercial TVS would derate or fail. ## DO-201AA axial package — board-fit and mounting Through-hole mounting in a DO-201AA (DO-27) axial package. The lead spacing and body diameter match the standard TVS footprint used across the 1.5KE family — no board layout change if migrating from another 1.5KE56 variant. Tape-and-reel packaging supports automated insertion for volume builds.","metaTitle":"Vishay 1.5KE56CAHE3_A/C TVS Diode, 1500W, AEC-Q101","metaDescription":"Active Vishay 1.5KE56CAHE3_A/C bidirectional TVS, 1500W peak pulse, 47.8V standoff, AEC-Q101 qualified.
