SP1255PUTG - SP1255P Series

Series: SP1255P Questions? Contact Littelfuse Support

The SP1255P 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 VBUS pin up to 100A (tP=8/20μs) per the IEC61000-4-5 standard. The SP1255P provides superior protection for current intensive applications such as fast charging peripherals.

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.
