The part ships on Tape & Reel (TR), compatible with automated pick-and-place at 8 mm tape width — no MSL bake required for standard reflow profiles up to 260°C peak.","metaTitle":"1.5SMC43CAHE3_A/I Vishay TVS Diode, 1.5kW, AEC-Q101","metaDescription":"Active Vishay 1.5SMC43CAHE3_A/I bidirectional TVS diode, 1.5 kW peak pulse power, 36.8 V standoff, AEC-Q101 automotive grade.
