The 22.5V maximum clamping voltage at the 66.7A peak pulse current limits the voltage stress on downstream FETs and ICs rated for 30V or 40V abs-max, giving a derating buffer that improves system reliability over temperature. ## Package and board-fit for DO-214AB Housed in the DO-214AB (SMCJ) surface-mount package, the 1.5SMC16CAHE3/9AT shares the same footprint as other 1.5SMC series parts — the 0.050-inch (1.27 mm) terminal pitch and 0.220-inch (5.59 mm) body length fit standard reflow profiles with a 260°C peak soldering temperature.","metaTitle":"Vishay 1.5SMC16CAHE3/9AT TVS, 1500W, AEC-Q101, DO-214AB","metaDescription":"Automotive-grade 1.5SMC16CAHE3/9AT bidirectional TVS diode, 1500W peak pulse, 22.5V clamping, AEC-Q101 qualified.
