For shorter pulses the part can absorb significantly more peak power; the derating curve in the Vishay datasheet scales the 1500W figure linearly above 25°C to zero at 150°C. ## AEC-Q101 qualification and temperature range This part carries AEC-Q101 qualification, the automotive-grade discrete semiconductor stress test standard. The full operating junction temperature range extends from -65°C to +150°C, which covers under-hood and engine-bay thermal profiles with margin. The TransZorb® series is Vishay's branded TVS platform, optimized for clamping response time and surge energy absorption. The 'HM3' suffix in the order code indicates the automotive-grade AEC-Q101 qualified variant with a specific lead-frame and mold compound set for high-reliability applications.","metaTitle":"1.5SMC200AHM3_A/H Vishay TVS, 1.5kW, 171V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC200AHM3_A/H Zener TVS, 1500W peak pulse, 171V reverse standoff, AEC-Q101 qualified.
