Littelfuse Inc. has announced its latest low capacitance ESD protection TVS diode arrays (SPA Diodes) geared to provide remarkable ESD protection for current-intensive applications such as fast-charging peripherals or PoweredUSB. The SP1255P series incorporates three channels of ultra-low capacitance steering diodes with a low voltage TVS diode to deliver maximum ESD protection of the USB data and ID pins per the IEC 61000-4-2 standard, noted the company.

With a dynamic resistance of just 0.3, the devices provide clamping voltages up to 23 per cent lower than similar silicon solutions, Littelfuse said. 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.

Typical applications for the SP1255P series include ESD protection for smartphones, tablets and other portable electronics.

SP1255P series

The SP1255P series is offered in a small form factor ?DFN-6 package (1.8mm x 2mm x 0.55mm) that 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. The Automotive-grade quality (AEC-Q101 qualified) devices also ensure maximum reliability in the harshest environments, added the company.

The SP1255P series is available in quantities of 3,000. Sample requests can be placed through authorised Littelfuse distributors worldwide.
