New from ON Semiconductor are three transient voltage suppression devices for high-speed data lines. The ESD7008, MG2040 and ESD7104 provide electrostatic discharge (ESD) protection for high-speed data and video lines while offering low capacitance, high signal integrity and low clamping voltages.
Designed to protect up to four high-speed differential pairs (eight lines), the ESD7008 delivers industry ESD protection with extremely low I/O to ground capacitance of 0,12 pF. It is housed in a flow-through UDFN18 package that supports easy PCB layout and matched trace lengths necessary to maintain consistent impedance for high-speed lines.
Emerging applications for the ESD7008 include USB 3.0 where it protects three high-speed pairs plus Vcc and Iden lines for a fully integrated solution, V-by-One and Thunderbolt (Light Peak). Other popular applications where the device is relevant include HDMI, DisplayPort and LVDS.
The MG2040 transient voltage suppressor is designed specifically to provide full functionality integrated ESD protection for up to 14 lines serving all active pins of HDMI and DisplayPort interfaces. Ultra-low capacitance of 0,35 pF typical (I/O to GND), flow-through package design, and a low ESD clamping voltage make the device ideal for protecting voltage sensitive high-speed data lines.
Housed in a space efficient UDFN10 package, the ESD7104 allows easy layout and matched trace lengths between high-speed differential lines in applications such as USB3.0, HDMI, eSATA 3.0 and DisplayPort. It provides low-capacitance ESD protection for up to four lines and has a typical I/O to GND capacitance of 0,3 pF.
All three new transient voltage suppressors have an operating junction temperature range of -55°C to +125°C. They also exceed the protection requirements of IEC 6100-4-2 (level 4) by protecting over 15 kV contact and air discharge.
