The thermal junction limit is 150°C, so the board-level heatsinking path and local ambient define how many repeated transients the part absorbs before its junction temperature budget is exhausted. ## DO-214AB SMC footprint and assembly context The DO-214AB (SMCJ) package ships in Tape & Reel — the cathode band marks the unidirectional polarity direction, which must align with the protected rail on the PCB.","metaTitle":"Vishay 1.5SMC75A-M3/9AT TVS Diode, 1500W, 64.1V Standoff","metaDescription":"Vishay 1.5SMC75A-M3/9AT unidirectional TVS diode, 1500W peak pulse, 64.1V standoff, 104V clamping.
