The axial leads handle the thermal cycling of the 175°C junction without the solder-joint fatigue risk of a large SMD package on a hot board.","metaTitle":"1.5KE27AHE3_B/C Vishay TVS, 1500W, 23.1V Standoff, DO-201AA","metaDescription":"Vishay 1.5KE27AHE3_B/C Zener TVS diode, 1500W peak pulse, 23.1V reverse standoff, AEC-Q101 automotive grade.

Breakdown starts at a minimum of 25.7V, and clamping is limited to 37.5V maximum at the 42A peak pulse current rating (10/1000µs waveform)."},{"question":"Is the 1.5KE27AHE3_B/C automotive qualified?","answer":"Yes, it carries AEC-Q101 qualification, which certifies the device for automotive-grade reliability — temperature cycling, ESD immunity, and high-temperature reverse bias stress are screened.
