05124 ET721 Only One Name Means ProTek’Tion™ ultra low capacitance steering diode array Description The ET721 is a low capacitance and low leakage steering diode array capable of protecting up to six (6) high speed data lines. Its ultra low capacitance allows maintenance of signal integrity for high-speed data lines while protecting the circuit ICs from the damage of severe transients. An extremely low leakage current makes the ET721 suitable for battery powered devices. The ET721 is available in a SO-8 package. This device meets all the applicable voltage immunity standards, including IEC 61000-4-2 (ESD), 61000-4-4 (EFT) and 61000-4-5 (Surge). SO-8 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): 12A, 8/20µs - Level 1(LineGnd) & Level 2(Line-Line) • Low Clamping Voltage • Provides Six Lines of Protection • Low Leakage Current: <200nA • Ultra Low Capacitance: 3pF Typical • RoHS Compliant • REACH Compliant • Ethernet 10/100/1000 Base T • SMART Phones • Set-Top Box Interface • FireWire & USB Interfaces • Sensors Mechanical characteristics • Molded JEDEC SO-8 Package • Approximate Weight: 70 milligrams • Lead-Free Pure-Tin Plating (Annealed) • Solder Reflow Temperature: Pure-Tin - Sn, 100: 260-270°C • 12mm Tape and Reel Per EIA Standard 481 • Flammability Rating UL 94V-0 PIN CONFIGURATION 05124.R9 9/10 +VCC I/O 6 I/O 5 I/O 4 8 7 6 5 1 2 3 4 I/O 1 I/O 2 I/O 3 -VEE Page 1 www.protekdevices.com 05124 ET721 Only One Name Means ProTek’Tion™ typical device characteristics MAXIMUM RATINGS @ 25°C Unless Otherwise Specified PARAMETER SYMBOL VALUE UNITS TA -55 to 150 °C Storage Temperature TSTG -55 to 150 °C Continuous Power Dissipation PPC 145 mW Operating Temperature ELECTRICAL CHARACTERISTICS PER LINE @ 25°C Unless Otherwise Specified PART NUMBER ET721 DEVICE MARKING REPETITIVE PEAK REVERSE VOLTAGE (Note 1) STA typical forward voltage VRRM VOLTS 8/20µs @ 1A VF VOLTS 50 2 MAXIMUM peak pulse forward CURRENT MAXIMUM quiescent supply CURRENT (Note 3) @ 20v IRq nA typical CAPACITANCE @ 8/20µs IFM Amps MAXIMUM REVERSE LEAKAGE CURRENT (Note 2) V RRM IR nA 12 20 200 3 0V, 1MHz Cj pF Note 1.
