LCDA12C-8 and LCDA15C-8
Low Capacitance TVS Diode Array
For Multi-mode Transceiver Protection
PROTECTION PRODUCTS
Description
Features
The LCDAxxC-8 has been specifically designed to
protect sensitive components which are connected to
data and transmission lines from over voltages caused
by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning.
The low capacitance array configuration of the
LCDAxxC-8 allows the user to protect eight high-speed
data or I/O lines. They may be used on systems
operating from 5 to 15 Volts. The high surge capability
(500W, tp=8/20µs) makes the LCDAxxC-8 suitable for
telecommunications systems operating in harsh transient environments. The low inductance construction
minimizes voltage overshoot during high current
surges.
The features of the LCDAxxC-8 are ideal for protecting
multi-protocol transceivers in WAN applications such as
Frame Relay systems, routers, and switches.
