Graded as Automotive and qualified to AEC-Q101, this part meets the stress and reliability requirements for under-hood and chassis-mounted electronics — the -65°C to 150°C operating range covers the full automotive thermal profile, from cold cranking to engine bay heat soak. ## DO-214AB footprint and peak current Packaged in DO-214AB (SMC) — a standard surface-mount footprint for TVS diodes rated at this power level. The single bidirectional channel protects a single line pair against both positive and negative transients, simplifying layout for DC rails or signal lines that swing both polarities. Peak pulse current is 6.1 A for the 10/1000 µs waveform at the clamping voltage — a significant margin above the normal line current in most 154 V applications, ensuring the diode handles the surge without exceeding its thermal limits.","metaTitle":"1.5SMC180CAHM3/H Vishay TVS, 1500W, Bidirectional, DO-214AB","metaDescription":"Vishay 1.5SMC180CAHM3/H bidirectional Zener TVS, 1500W peak pulse, 154V standoff, AEC-Q101 automotive grade.
