This SP1224 TVS diode has a lightning surge rating of 100A (8/20 as defined in IEC 61000-4-5 2nd edition) and is intended for USB VBUS protection. It provides superior protection for current intensive applications such as the USB fast charging circuits. The SP1224 TVS is offered in a space saving 2.0 x 1.8 mm µDFN package with a typical height of 0.55 mm. This small form factor makes this component ideal for smart phones, tablets, and other portable electronics that are footprint challenged.
