TVS Diode Array (SPA Diodes) Low Capacitance ESD and Surge Protection - SP1255P Series GREEN RoHS Pb SP1255P Series 0.5pF, 12kV Diode Array for USB Description The SP1255P integrates three 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 IEC 61000-4-2 standard. An additional 12V TVS diode is included to provide lightning surge protection for the USB V pin up to 100A (t =8/20s) per BUS P the IEC 61000-4-5 standard. The SP1255P provides superior protection for current intensive applications such as fast charging peripharals. The SP1255P comes in a space saving 2.0x1.8mm DFN package with a typical height of 0.55mm making it an ideal solution for smart phones, tablets, and other portable electronics.
