Supplied on tape and reel, compatible with JEDEC MSL-1 reflow profiles — no moisture bake required before assembly if the seal is intact. ## Active production — no last-time-buy window open No official successor or second-source cross-reference is recorded; the 1.5SMC180 base number is the direct orderable variant for the 154 V standoff voltage.","metaTitle":"Vishay 1.5SMC180AHM3/H TVS, 154V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC180AHM3/H automotive TVS diode, AEC-Q101, 1500W peak pulse, 154V reverse standoff, 246V clamp.
