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.
