SRDA05 Series TVS Diode Array - Lightning Surge

SRDA05 Series TVS Diode Array - Lightning Surge

Littelfuse, Inc. has introduced the SRDA05 series of TVS SPA diode arrays. The SRDA05 series is designed to protect telecommunications data lines against electrostatic discharge (ESD) and high surge events, providing a 20 percent higher power and surge handling capability than competitive devices on the market. By integrating low capacitance steering diodes with an additional zener diode, the SRDA05 offers more design margin to electrical threats defined by industry standards and increased ESD protection without performance degradation.

Typical applications of these devices include tertiary (IC side) protection for telecommunication interfaces such as T1/E1/T3/E3 data lines, xDSL interfaces, RS-232/RS-485 interfaces, 10/100/1000 Ethernet interfaces and video lines. They are also suitable for industrial and medical equipment applications. SPA Family of TVS Diode Arrays
