TVS diode array packs five devices inside a single flip-chip (FCiP) package
Mouser is now stocking the SP1012 TVS diode array from Littelfuse - one of
the first general-purpose electrostatic discharge (ESD) protection devices
of its kind to pack five ESD diodes inside a flip-vhip (FCiP) package - a 5x
improvement over previous implementations.
The miniature, five-channel bidirectional TVS array is one of the most
densely designed ESD protection devices available, helping developers reduce
printed circuit board (PCB) space and costs due to its small 0402-size
square millimetre footprint.
The device provides circuit protection by safely absorbing repetitive ESD
strikes at the maximum level (Level 4) specified in the IEC 61000 4 2
international standard without any performance degradation. The
bidirectional configuration provides symmetrical ESD protection for data
lines when AC signals are present. This diode array provides greater than
±15kV protection per the IEC61000-4-2 international standard, giving
developers higher product reliability. For electrical fast transient (EFT)
ratings, the SP1012 is specified at 40A (5/50ns) per the EC61000-4-4
international standard. The device is also co-terminated, permitting
flexible ground pad layout. The SP1012’s very low 0.48 ohms dynamic
resistance supports the low clamping voltages needed for protecting
The SP1012 features a capacitance of 6.5pF with bidirectional polarity,
while offering a nominal 6V standoff voltage. This provides protection on
95% of both current and future user interfaces. The device has an operating
temperature of -40C to +125C and its FCiP package fits 0402 footprints.
