The DO-201AA axial-lead package (also known as DO-27) is through-hole mounted, suited for point-of-entry protection on power inputs where board space is not the constraint. ## Sourcing an obsolete AEC-Q101 TVS The AEC-Q101 qualification means the device has passed automotive-grade reliability testing (temperature cycling, ESD, humidity, and high-temperature reverse bias). If the application is a non-automotive design, a commercial-grade TransZorb with the same electrical ratings may be available at lower cost — but the AEC-Q101 data package is the differentiator for designs that require PPAP traceability.","metaTitle":"Vishay 1.5KE82CAHE3/51 TransZorb TVS, 1500W, 70.1V","metaDescription":"Obsolete Vishay 1.5KE82CAHE3/51 bidirectional TVS diode, 1500W peak pulse, 70.1V standoff, AEC-Q101.
