Littelfuse’s SP1255P TVS diode array provides superior protection from ESD strikes and severe transient surges in mobile applications which use wired data and power lines, such as USB2.0 and micro-USB ports.

The device integrates three channels of low-capacitance steering diodes with a low-voltage TVS diode to provide ESD protection of USB data and identification pins in accordance with the IEC 61000-4-2 standard. It features clamping voltages as much as 23% lower than those of similar silicon devices. Offering high surge-current protection, the SP1255P protects the host system against lightning-induced transients of up to 100A on the USB voltage bus.

• ±30kV ESD protection
• 0.5pF capacitance
• Small 2.0mm x 1.8mm package
• 0.3Ω dynamic resistance
