Packaged in Tape & Reel (TR) format, it suits automated pick-and-place assembly for high-volume production lines. The surface-mount package eliminates through-hole hand-soldering steps in automotive ECU and telecom line-card builds.","metaTitle":"Vishay 1.5SMC33AHM3_A/I TVS, 1500W, 28.2V Standoff, AEC-Q101","metaDescription":"Active Vishay 1.5SMC33AHM3_A/I Zener TVS diode, 1500W peak pulse, 28.2V standoff, AEC-Q101 automotive grade, DO-214AB SMC.
