Littelfuse, Inc. has introduced the SP1255P Series Low Capacitance ESD Protection TVS Diode Arrays (SPA® Diodes), which are designed to provide superior ESD protection for current-intensive applications, such as fast-charging peripherals or PoweredUSB. The SP1255P Series integrates three channels of ultra-low capacitance steering diodes with a low voltage TVS diode to provide maximum ESD protection of the USB data and ID pins per the IEC 61000-4-2 standard. With a dynamic resistance of just 0.3 W, they provide clamping voltages up to 23 percent lower than similar silicon solutions. A high surge current protection device with a working voltage of 12 V is allocated for Vbus protection; this device protects against lightning level fast transients of up to 100 A on the USB Vbus line.
Typical applications for the SP1255P Series include ESD protection for smartphones, tablets, and other portable electronics.
SP1255P Series Low Capacitance ESD Protection TVS Diode Arrays offer these key benefits:
· Low dynamic resistance of 0.3Wprovides clamping voltages up to 23 percent lower than similar silicon solutions to offer superior protection for current-intensive applications such as fast-charging peripherals.
· Robust ESD capability for Vbus or USB data pin protection allows manufacturers to claim ESD protection above the maximum level as stated in the IEC standard.
· Small form factor µDFN-6 package (1.8 x 2.0 x 0.55 mm) simplifies the PCB layout by allowing the traces to run directly underneath the device without the need for stub traces that can cause signal degradation.
· Automotive-grade quality (AEC-Q101 qualified) ensures maximum reliability in the harshest environments.
The SP1255P Series is available in quantities of 3,000.
