Its minimum breakdown voltage of 14.3 V and maximum clamping voltage of 27.2 V at the peak pulse current of 147 A (8/20 µs waveform) define the protection envelope. The 600 W peak pulse power rating (10/1000 µs) gives the energy-handling budget for industrial and general-purpose surge protection. ## Package and footprint Housed in the DO-214AA (SMB) surface-mount package, the SM6T15A uses a standard two-pad footprint common across the SMB family.","metaTitle":"STMicroelectronics SM6T15A TVS Diode, 600W, DO-214AA","metaDescription":"STMicroelectronics SM6T15A TRANSIL™ TVS diode, 600W peak pulse power, 12.8V standoff, 14.3V min breakdown.
