ESD Diode Protects High-Speed Interfaces from Static Electricity

November 21, 2014 By admin Comments are Off

Toshiba America Electronic Components, Inc. (TAEC) announced the introduction of a new ESD (electrostatic discharge) protection diode – the DF5G7M2N. Built to protect equipment attached to communication lines, the DF5G7M2N shields high-speed interfaces such as USB3.1, HDMI®, DisplayPort™ and Thunderbolt™ from static electricity. It can also be used to protect small portable devices such as smartphones and tablets from ESD events.

Housed in a DFN5 package that reduces its footprint to less than 50 percent compared with the DF10G7M1N (DFN10: 2.5×1.0 mm, 4bit), the DF5G7M2N simplifies wiring design, making it suitable for high density mounting. Additionally, Toshiba’s new ESD diode realizes low capacitance and low dynamic resistance by optimizing the process, suppressing signal quality deterioration and providing high ESD resistance.

“Static electricity on high speed data lines can cause numerous problems, including effecting quality and reliability,” noted Talayeh Saderi, senior business development manager for TAEC. “Our new ESD diode helps to provide stable operation and reliability for these voltage-sensitive lines.”

Features of the DF5G7M2N include: Low capacitance and low dynamic resistance (CT=0.2 pF , RDYN=1 ); Suppresses deterioration in signal quality (insertion loss) by lowering capacitance (|S21|(2) = -1.3 dB @f=10 GHz); Electrostatic discharge immunity tests IEC61000-4-2(Contact discharge): Over ±8 kV; DFN5 package (1.3×0.8 mm); and bidirectional 4 line multi-bit (a flow-through type). Toshiba’s new ESD diode is available now, with budgetary pricing estimated at $0.06.
