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. Pinout SOT143 Features • ESD, IEC61000-4-2 , • Low capacitance of 6.0pF ±30kV contact discharge, (TYP) per I/O ±30kV air discharge • Low clamp voltage Vcc GND • EFT, IEC61000-4-4, 80A • Small SOT143 (JEDEC TO- (tp=5/50ns) 253) packaging • Lightning protection, • Moisture Sensitivity Level IEC61000-4-5, 25A (MSL-1) (t =8/20µs) p I/O 1 I/O 2 Applications Functional Block Diagram • T1/E1 IC/Secondary • ISDN S/T Interface PIN 4 Protection • Video Lines • Ethernet 10BaseT • Microcontroller Input • WAN/LAN Equipment Protection PIN 2 PIN 3 Application Example I/O I/O V CC GND (PIN 1) 1 4 Additional Information 2 3 Datasheet Resources Samples The SR05 integrates a TVS Diode between the Vcc and Gnd pins. This allows the array to protect the power supply Life Support Note: against ESD and lighting surges when these pins are both Not Intended for Use in Life Support or Life Saving Applications connected in the application.
