05151 Only One Name Means ProTek’Tion™ ET108 low caPaciTancE sTEERing diodE aRRay dEscRiPTion The ET108 is a low capacitance steering diode array designed to protect circuit applications with a bus voltage of less than 25 volts from the effects of Electrostatic Discharge (ESD). This device is designed for the protection of four I/O ports. With a low input capacitance per line of less than 6pF, pulse two diode pairs for each line, the ET108 provides both positive and negative transient protection. 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 • 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) • Provides 4 Lines/Ports of Protection • Low Leakage Current: < 2.0µA • Ultra Low Capacitance: 6pF per Diode • RoHS Compliant • REACH Compliant aPPlicaTions • • • • Ethernet 10/100/1000 Base T RS-422 and RS-485 Microcontrollers USB Interface 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 GND REF 1 GND REF 1 V REF 2 V REF 2 8 7 6 5 1 I/O 2 I/O 3 I/O 4 I/O 05151.R6 9/10 Page 1 www.protekdevices.com 05151 Only One Name Means ProTek’Tion™ ET108 TyPical dEvicE chaRacTERisTics MaXiMuM RaTings @ 25°c unless otherwise specified PaRaMETER Operating Temperature Storage Temperature Continuous Power Dissipation syMBol TA TSTG PPC valuE -55 to 150 -55 to 150 730 uniTs °C °C mW ElEcTRical chaRacTERisTics PER linE @ 25°c unless otherwise specified PaRT nuMBER dEvicE MaRking REPETiTivE PEak REvERsE volTagE vRRM volTs ET108 noTE ET108 25 MaXiMuM FoRwaRd volTagE 8/20µs @ 50ma vF volTs 1.2 MaXiMuM PEak PulsE FoRwaRd cuRREnT (Fig. 1) @ 8/20µs i FM aMPs 12 MaXiMuM FoRwaRd volTagE 8/20µs @ 12a vF volTs 9 MaXiMuM REvERsE lEakagE cuRREnT vRRM iR µa 2 TyPical caPaciTancE (note 1) cj pF 6 1.
