Smaller, uprated ESD protection diode for high-speed interfaces

November 21, 2014 // By Graham Prophet
Toshiba Electronics Europe ESD (electrostatic discharge) protection diode type DF5G7M2N is rated to protect equipment attached to communication lines, using 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.

In a 1.3 x 0.8 mm DFN5 package that reduces its footprint to less than 50% of that of similar products, the DF5G7M2N simplifies wiring design, making it suitable for high density mounting. This ESD diode presents low capacitance and low dynamic resistance (CT=0.2 pF, RDYN=1Ω). It also suppresses signal quality deterioration (insertion loss) by lowering capacitance (|S21|2 = -1.3 dB @f=10 GHz) and provides high ESD resistance, ±8 kV.
