TVS diode arrays

18 March 2015 Circuit & System Protection

Littelfuse’s SP5001, SP5002 and SP5003 TVS diode arrays are highly integrated common-mode filters that provide both electrostatic discharge protection and common-mode EMI filtering for systems that use high-speed differential serial interfaces.

Since they can protect and filter two (SP5001 and SP5003) or three (SP5002) differential line pairs, applications for these AEC-Q101 qualified devices include consumer electronics such as smartphones and tablet computers, finding applications in MIPI camera and display, HDMI, DVI display and DisplayPort interfaces, etc.

High common-mode stopband attenuation (up to -30 dB) in the cellular frequency ranges means these devices effectively prevent high-speed data lines from interfering with radio frequencies, while their large differential bandwidths up to 4 GHz allow differential serial buses to operate unimpeded in normal operation.

Low channel capacitance of 0,8 pF makes this an ESD protection solution that is virtually invisible during normal operation and extremely effective against ESD attack. The components’ low-profile DFN packages are limited to 0,8 mm, permitting usage in wireless, tablet and infotainment applications.
