The 1500W rating is the peak pulse power dissipation for the 10/1000µs double-exponential waveform — the standard telecom surge shape. For shorter pulses (8/20µs), the peak power capability is higher; the datasheet's peak pulse power vs pulse duration curve gives the derating for non-standard waveforms. ## AEC-Q101 and the -65 to 150°C operating range Qualified to AEC-Q101, this part meets the automotive discrete semiconductor reliability standard: temperature cycling, high-temperature reverse bias, and preconditioning for moisture sensitivity. The -65°C to 150°C junction temperature range covers under-hood and engine-bay thermal profiles — a 125°C ambient with self-heating still leaves margin before the 150°C absolute maximum. The A suffix in the part number indicates the automotive-grade screening. The HM3 suffix denotes the halogen-free, RoHS-compliant version with matte-tin plated terminations — no whisker-risk concerns for long-life automotive or telecom deployments. ## DO-214AB SMC — board-fit and thermal note Housed in the DO-214AB (SMC) package, the device footprint is shared with many 1500W TVS diodes across the 1.5SMC series. The cathode band on the package body marks the unidirectional orientation; the single-channel Zener structure means the part protects one line per device. The copper pad area under the package on the PCB sets the thermal resistance — a 600mm² pad on 2oz copper drops RθJA significantly compared to a minimal land pattern.","metaTitle":"1.5SMC180AHM3_A/H Vishay TVS, 1500W, 154V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC180AHM3_A/H Zener TVS, 1500W peak pulse, 154V standoff, 246V clamp, AEC-Q101 automotive grade, DO-214AB SMC.
