TVS Diode Arrays (SPA® Diodes) Lightning Surge Protection- SR05 Series SR05 Series 5V 25A Diode Array RoHS Pb GREEN Description The SR05 consists of four, low capacitance steering diodes and a low voltage TVS diode that provide protection against ESD and lightning surge events. Each channel or I/O pin can safely absorb up to 25A (tp=8/20μs) and repetitive ESD strikes above the maximum level (Level 4) specified in the IEC 61000-4-2 international standard without performance degradation. The low loading capacitance makes it ideal for protecting high-speed telecommunication data lines. SOT143 Pinout Features Vcc GND • ESD, IEC61000-4-2 , ±30kV contact discharge, ±30kV air discharge • Low capacitance of 6.0pF (TYP) per I/O • EFT, IEC61000-4-4, 80A (tp=5/50ns) • Small SOT143 (JEDEC TO253) packaging • Low clamp voltage • Lightning protection, IEC61000-4-5, 25A (tp=8/20µs) I/O 1 I/O 2 Applications Functional Block Diagram PIN 4 • T1/E1 IC/Secondary Protection • ISDN S/T Interface • Ethernet 10BaseT • Microcontroller Input Protection • Video Lines • WAN/LAN Equipment PIN 2 PIN 3 Application Example I/O GND (PIN 1) I/O VCC 1 4 2 3 Additional Information Datasheet Resources Samples Life Support Note: Not Intended for Use in Life Support or Life Saving Applications The products shown herein are not designed for use in life sustaining or life saving applications unless otherwise expressly indicated. The SR05 integrates a TVS Diode between the Vcc and Gnd pins. This allows the array to protect the power supply against ESD and lighting surges when these pins are both connected in the application. © 2013 Littelfuse, Inc.
