onsemi SMSxC 5-Line ESD Protection Diode Arrays

onsemi SMSxC 5-Line ESD Protection Diode Arrays are designed to safeguard high-speed data lines from electrostatic discharge (ESD) damage in sensitive electronic systems. These arrays feature a monolithic common anode design, which protects five independent lines in a single TSOP-6 package, providing robust interface protection without compromising signal integrity. With a fast response time and compliance with IEC 61000-4-2 Level 4 standards, the onsemi SMSxC arrays are ideal for use in computers, printers, automotive electronics, networking communication, and more. The integrated design simplifies PCB layout and enhances reliability in space-constrained applications.
