Supplied in Tape & Reel (/9AT suffix) — compatible with standard SMT pick-and-place lines.","metaTitle":"Vishay 1.5SMC6.8CA-E3/9AT TVS Diode, 5.8V Standoff, 1.5kW","metaDescription":"Vishay 1.5SMC6.8CA-E3/9AT bidirectional TVS diode, 5.8V standoff, 6.45V breakdown, 10.5V clamping, 143A peak pulse, DO-214AB.
