Littelfuse Inc. has released the SP1255P Series Low Capacitance ESD Protection TVS Diode Arrays (SPA Diodes) for current-intensive applications such as PoweredUSB, USB 2.0 port, smartphones and tablets.

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 0.3?, the SPA Diodes provide clamping voltages up to 23 per cent lower than similar silicon solutions. A high surge current protection device with a working voltage of 12V is allocated for Vbus protection. This device protects against lightning level fast transients of up to 100A on the USB Vbus line.

The small form factor?DFN-6 package (1.8mm x 2mm x 0.55mm) 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 (AECCQ101 qualified) ensures maximum reliability in the harshest environments.

The 470 Series NANO2 Subminiature Fuse is available in quantities of 1,500 and the 476 Series NANO2 Subminiature Fuse is available in quantities of 1,000, both in tape and reel packaging. Sample requests can be placed through authorised Littelfuse distributors worldwide.
