LCDA12C-8 and LCDA15C-8
Low Capacitance TVS Diode Array
For Multi-mode Transceiver Protection
PROTECTION PRODUCTS
Description
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 tran-
sients (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 tran-
sient 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.
