The 1500 W (1.5 kW) peak pulse rating puts this part in the mid-power TVS class — suitable for telecom line-card protection and lower-current automotive rails rather than full load-dump scenarios. The 10/1000 µs surge waveform rating (versus the 8/20 µs IEC surge) reflects telecom-class testing: the longer pulse width means the same peak current delivers more total energy into the clamping voltage, so the clamping impedance the downstream load sees during the event is the critical design parameter. ## AEC-Q101 — automotive temperature and qualification grade AEC-Q101 qualification is the hard floor here: this is not a commercial-grade TVS dressed in automotive marketing. The junction temperature range of -65°C to 150°C (TJ) covers the full automotive ambient band — from cold-soak cold start to under-hood proximity. For an ECU input or an automotive communication bus protection rail, the 150°C TJ ceiling means the part survives the thermal environment without derating to a safety margin that would compromise the clamping level. ## SMT integration and Tape & Reel packaging Tape & Reel packaging is the standard auto-reel for high-volume assembly; confirm the reel count and leader/trailer length against your pick-and-place tolerance profile for the specific reel lot. ## Sourcing — active production, no official successor on record The 1.5SMC82AHM3/I is listed as Active by Vishay General Semiconductor — Diodes Division. No official successor or cross-reference has been published for this specific order code. The 1.5SMC82 base part number maps to the 82 V nominal Zener voltage family — any cross-reference must preserve the standoff, clamping, and peak pulse ratings to be electrically equivalent.","metaTitle":"Vishay 1.5SMC82AHM3/I, 70.1V standoff TVS diode, AEC-Q101","metaDescription":"Vishay 1.5SMC82AHM3/I Zener/TVS diode, 70.1V standoff, 113V clamping, 1.5 kW peak pulse, AEC-Q101, DO-214AB SMC.
