05268 SRV2.8-4 Only One Name Means ProTek’Tion™ ultra low capacitance steering diode/tvs array Description The SRV2.8-4 is an ultra low capacitance steering diode/TVS array. This device can be used in applications such as video cards, SMART phones, Gigabit Ethernet and other computer interfaces. Designed for ESD protection, the SRV2.8-4 can clamp the effects of electrical fast transients on the power bus. The SRV2.8-4 combines low capacitance steering diodes for up to four individual data or transmission lines and one TVS diode for power bus protection. This device is available in the space-saving SOT-23-6 package configuration, which minimizes lead inductance to prevent overshoot voltages during high ESD current events. The SRV2.8-4 meets the IEC 61000-4-2, 61000-4-2 and 61000-4-5 requirements. sot-23-6 package Features applications • Compatible with IEC 61000-4-2 (ESD): Air 15kV, Contact 8kV • Compatible with IEC 61000-4-4 (EFT): 40A, 5/50ns • Compatible with IEC 61000-4-5 (Surge): 24A, 8/20µs - Level 2(LineGnd) & Level 3(Line-Line0 • 600 Watts Peak Pulse Power per Line(tp = 8/20µs) • ESD Protection > 25 kilovolts • Low Clamping Voltage • Protection for 4 Lines • Ultra Low Capacitance: 3.5pF Typical • RoHS Compliant • REACH Compliant • Gigabit Ethernet • SMART Phones • Portable Electronics • Video Card Interfaces • USB 2.0 Interfaces • DVI Interfaces mechanical characteristics • Molded JEDEC SOT-23-6 Package • Approximate Weight: 16 milligrams • Lead-Free Nickel Paladium Gold Plating • Solder Reflow Temperature - 260-270°C • Flammability Rating UL 94V-0 • 8mm Tape and Reel per EIA Standard 481 PIN CONFIGURATION 05268.R1 10/12 I/O 1 1 6 I/O 4 GND 2 5 REF I/O 2 3 4 I/O 3 Page 1 www.protekdevices.com 05268 SRV2.8-4 Only One Name Means ProTek’Tion™ typical device characteristics MAXIMUM RATINGS @ 25°C Unless Otherwise Specified PARAMETER Peak Pulse Power (tp = 8/20µs) - See Figure 1 Operating Temperature SYMBOL VALUE UNITS PPP 600 Watts TL -55 to 150 °C Storage Temperature TSTG -55 to 150 °C Forward Rating (5ms @ 25°C, IF = 10mA) VF 0.5 Min. - 1.2 Max.
