Littelfuse introduces the SP3312T series 3.3V, 15A TVS diode array (Silicon Protection Array (SPA) Diode), which integrates four channels (two differential pairs) of low-capacitance diodes to protect sensitive I / The O-pin protects products such as smartphones, tablets and other portable devices from damage caused by lightning surges and electrostatic discharge (ESD).
Compared to similar market solutions, the SP3312T series provides circuit designers with a 71% lower capacitance solution than other devices, helping to maintain signal integrity and minimize data loss. Compared to competing solutions, it also provides up to 150% of high-power processing capability. This rugged device can safely sink 15A current in accordance with IEC 61000-4-5 (tp = 8 / 20μs) without degrading performance, and it complies with IEC 61000-4-2's minimum ± 30kV ESD.
Target applications include 10/100/1000 Ethernet, LAN / WAN devices, home automation and security, thanks to the excellent clamping performance of the SP3312T, in a space-saving 2.0 x 1.0mm μDFN-08 package with a typical height of 0.4mm Compared to existing solutions, ultra-fast silicon-based ESD active protection is designed to shunt transient voltage events to levels just above the standard operating voltage, providing a better choice.
"The SP3312T series provides an excellent alternative to other market solutions, providing ESD and surge protection on Gigabit Ethernet ports," said Tim Micun, TVS diode array product line manager. "They have extremely low capacitance for printed circuits. The board design provides greater flexibility and simplifies compliance with the industry's pass / fail eye test, eliminating the hassle of protecting gigabyte interfaces. "
