Littelfuse, Inc., has introduced a series of low capacitance TVS diode arrays optimized to protect electronic equipment that may experience destructive electrostatic discharges (ESDs). SP814x Series TVS Diode Arrays (SPA® Diodes) integrate four or six channels of ultra-low-capacitance rail-to-rail diodes and an additional zener diode to safely absorb repetitive ESD strikes above the maximum level specified in the IEC61000-4-2 international standard (±8kV contact discharge) without performance degradation. Their extremely low loading capacitance (1.0 pF typ. per I/O), lower series resistance than semiconductor-based devices, and fast response also makes them ideal for protecting electronics with high speed signal pins, such as HDMI2.0, USB3.0, USB2.0 and IEEE1394.
Low leakage current (25 nA typical at 5V) extends battery life and preserves signal integrity because excessive leakage can be seen as additive capacitance for a high-speed differential pair. Enhanced ESD capability (±22 kV contact, ±22 kV air) permits manufacturers to achieve ESD protection beyond the maximum level stated in the IEC standard and protects against a multitude of other threats to ensure product reliability in the field.
Applications for the SP814x Series include LCD/PDP TVs, external storage, DVD/Blue-Ray players, desktops/servers, notebooks/tablets, set-top boxes, mobile phones, flash memory cards and digital cameras.
The SP814x Series is provided in tape and reel format in quantities of 3,000.
