1 ULTRA LOW CAPACITANCE MULTI-LINE STEERING DIODE ARRAY DESCRIPTION The are a low distortion steering diodes. These devices are intended for use in high frequency analog or digital data I/O ports for protection against Electrostatic Discharge (ESD) and Electrical Fast Transients (EFT). The is connected between rail-to-rail voltage bus or rail-to-ground for clamping and diverting overvoltage transients for the protection of sensitive network interface circuits. This series provides low capacitance, which insures signal integrity up to 900MHz, while complete isolation between adjacent diodes keeps cross-talk to a minimum. The is available in a SO- package and meets the IEC , IEC and IEC requirements. SO- PACKAGE FEATURES Compatible with IEC (ESD): Air - 15kV, Contact - 8kV Compatible with IEC (EFT): 40A - 5/50ns Compatible with IEC (Surge): 4A, 8/0µs - Level (Line- Gnd) & Level 3(Line-Line) 500 Milliwatt Continuous Power Dissipation Low Insertion Loss & Cross-Talk ESD Protection > 5 kilovolts Protects 8 I/O Lines Working Voltage > 50 Volts Low Leakage Current < 0.1µA Ultra Low Capacitance: 5pF per Diode RoHS Compliant REACH Compliant APPLICATIONS High Frequency Data Lines RS-3 & RS-4 Interface Networks Ethernet 10/100 Base T Computer I/O Ports MECHANICAL CHARACTERISTICS Molded JEDEC SO- Package Approximate Weight: 0.15 grams Lead-Free Pure-Tin Plating (Annealed) Solder Reflow Temperature: Pure-Tin - Sn, 100: C 16mm Tape and Reel Per EIA Standard 481 Flammability Rating UL 94V-0 CIRCUIT DIAGRAM + I/O PORT GND OR (-) R15 5/18 Page 1
