The 9.1 A peak pulse current rating at the 10/1000 µs waveform defines the maximum surge the diode can sink — a key input for the PCB trace width and fuse coordination on the protected rail. This device does not include power-line protection features — it is intended for data, signal, and low-power DC bus clamping, not for AC mains or high-energy industrial surge paths. ## Package and board-level integration for DO-214AB The DO-214AB (SMC) package footprint is shared across the 1.5SMC family, allowing a single PCB land pattern to serve multiple voltage variants from 5.0 V to 220 V without layout changes.","metaTitle":"Vishay 1.5SMC120AHE3/9AT TVS, AEC-Q101, 1500W","metaDescription":"Vishay 1.5SMC120AHE3/9AT Zener TVS diode, AEC-Q101 qualified, 1500W peak pulse power, 102V standoff, DO-214AB.
