Description
The SMP1255P integrates 3 channels of ultra-low capacitance steering diodes and a low voltage TVS diode to
provide maximum protection of the USB data and ID pins against ESD per the IEC61000-4-2 standard. An
additional 12V TVS diode is included to provide lightning surge protection for the USB V_BUS pin up to 100A
(t_P=8/20μs) per the IEC61000-4-5 standard. The SMP1255P provides superior protection for current intensive
applications such as fast charging peripharals.
The SMP1255P comes in a space saving 2.0x1.8mm μDFN package with a typical height of 0.55mm making it an
ideal solution for smart phones, tablets, and other portable electronics.
