Rated for 1500 W peak pulse power, the DO-214AB (SMC) package dissipates the surge energy through the copper pad area under the cathode tab — the junction temperature range of -65 to 150 °C covers both cold-crank automotive start and hot underhood idle. ## Package and footprint for the layout engineer The single unidirectional channel means polarity matters — cathode band to the protected rail, anode to ground. No power line protection support (the part does not clamp rail-to-rail in both directions), so it is suited for DC bus clamping where the transient polarity is known.","metaTitle":"1.5SMC510AHM3_A/H Vishay TVS, AEC-Q101, 1.5kW, DO-214AB","metaDescription":"Vishay 1.5SMC510AHM3_A/H automotive TVS, AEC-Q101 qualified, 1.5kW peak pulse, 698V clamping, DO-214AB.
