Source: Littelfuse.comThe LittelFuse SP3312T Series 3.3V, 15A TVS Diode Array (SPA Diodes) integrates four channels (two differential pairs) of low capacitance diodes to protect sensitive I/O pins from damage due to lightning-induced surge events and electrostatic discharge (ESD). When compared to similar market solutions, the SP3312T Series is designed to provide circuit designers with 71% lower capacitance solution than other devices, which helps preserve signal integrity and minimize data loss. It also provides up to 150% higher power handling capacity than competing solutions. The device can absorb up to 15A per IEC 61000-4-5 (tp=8/20μs) without performance degradation and a minimum ±30kV ESD per IEC 61000-4-2.

Targeted applications include 10/100/1000 Ethernet, LAN/WAN equipment, home automation and security, which benefits from the SP3312T superior clamping performance in a space-saving 2.0 x 1.0mm μDFN-08 package with a typical height of 0.40mm Ultrafast acting silicon-based ESD protection, designed to shunt transient voltage events at a level just above standard operating voltages provides a superior choice when compared to existing solutions.

“The SP3312T Series offers a compelling alternative to other market solutions for ESD and surge protection on gigabyte Ethernet ports,” says Tim Micun, product manager for the TVS Diode Arrays line. “Their extremely low capacitance allows greater flexibility in printed circuit board design and simplifies compliance with the industry’s go/no-go eye diagram testing, which helps take the worry out of protecting gigabyte interfaces.”
