New steering diode protects against electrical transients in common computing interfaces
ProTek Devices introduced an ultra-low capacitance steering diode / TVS array for circuit protection against electrostatic discharge and surge transient voltages in Gigabit Ethernet, HDMI, USB, and other computing interfaces. The new component provides protection for six rail-to-rail data lines, making it optimal for applications with minimal board space.
The PLR0506LC is specifically ideal to protect high-speed data port like USB Type-C, but is also applicable for Gigabit Ethernet, FireWire, HDMI 1.4 and HDMI 2.0, SATA, and other PCIe interfaces. It is compatible with IEC standards 61000-4-2 (ESD): air 15kV, contact 8kV; with 61000-4-4 (EFT): 40A – 5/50ns; and with 61000-4-5 (lightning): 4A – 8/20 microseconds.
The typical capacitance I/O to ground is 0.4pF and I/O to I/O is 0.25pF at 0Vdcc, 1MHz. The PLR0506LC delivers ESD protection up to 25 kilovolts and has a low clamping voltage of 22V at 4A. Its ultra-low capacitance is 0.25pF typical, I/O to I/O.
