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 VBUS pin up to 100A (tP=8/20μs) per
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 μDFN
package with a typical height of 0.55mm making it an
ideal solution for smart phones, tablets, and other portable
electronics.
