MMAD1108
Only One Name Means ProTek’Tion™
ultra low capacitance multi-line steering diode array
Description
The MMAD1108 is a low distortion steering diode. This device is intended for use in high frequency analog or digital
data I/O ports for protection against Electrostatic Discharge (ESD) and Electrical Fast Transients (EFT). The MMAD1108
is connected between rail-to-rail voltage bus or rail-to-ground for clamping and diverting overvoltage transients for
the protection of sensitive network interface circuits.
This device provides low capacitance, which insures signal integrity up to 900MHz, while complete isolation between
adjacent diodes keeps cross-talk to a minimum. The MMAD1108 is available in a SO-16 package and meets the IEC
61000-4-2, IEC 61000-4-4 and IEC 61000-4-5 requirements.
