For shorter transients (8/20 µs, common in ESD or lightning), the peak current capability increases significantly — the datasheet's peak-pulse-power derating curve on page 4 shows the multiplier. The 1500 W pulse handles load-dump transients per ISO 7637-2 pulse 5a/5b without an external clamp. For telecom line-card protection, the DO-214AB package reflows alongside standard passives on a 260 °C peak profile (MSL per the Vishay tape-and-reel label).","metaTitle":"Vishay 1.5SMC300AHM3_A/I TVS, 1500W, AEC-Q101, DO-214AB","metaDescription":"Active Vishay 1.5SMC300AHM3_A/I Zener TVS diode, 1500W peak pulse, 414V clamping, AEC-Q101 automotive grade.
