Life Support Note:
Not Intended for Use in Life Support or Life Saving Applications
The products shown herein are not designed for use in life sustaining or life saving
applications unless otherwise expressly indicated.
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 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.
