The cathode band is clearly marked on the body; no pin 1 ambiguity for a two-terminal device. Reflow profile follows standard J-STD-020 for the package body, and the wide tab on the cathode side sinks heat into the board copper during a transient event. The 1500 W peak pulse rating (10/1000 µs waveform) means this part absorbs a 6.1 A surge and clamps it to 246 V max — the clamping voltage is what the downstream silicon sees, so the 246 V figure is the one to check against the input rating of the protected IC. ## Automotive-grade transient protection AEC-Q101 qualification certifies this TVS for automotive stress levels — temperature cycling, high-temperature reverse bias, and humidity bias. The operating range spans -65 °C to 150 °C junction, covering under-hood and cabin environments. Standoff voltage is 154 V — the DC bus or signal line must never exceed this in normal operation, or the TVS starts conducting leakage current. Breakdown triggers at 171 V minimum, giving a 17 V window between normal operation and the start of clamping. ## Sourcing and lifecycle posture Tape-and-reel packaging (TR) suits automated pick-and-place.","metaTitle":"Vishay 1.5SMC180AHM3_A/I TVS, 1500W, 154V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC180AHM3_A/I Zener TVS, 1500W peak pulse, 154V standoff, 246V clamp.
