PMMAD_15 Datasheet, PDF (1/7 Pages) Protek Devices – ULTRA LOW CAPACITANCE MULTI - LINE STEERING DIODE ARRAY

Only One Name Means ProTek’Tion™
ultra low capacitance multi-line steering diode array
PMMAD Series
SO-14 package
Description
The PMMAD Series are a low distortion steering diodes. These devices are 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
PMMAD Series 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 series provides low capacitance, which insures signal integrity up to 900MHz, while complete isolation between
adjacent diodes keeps cross-talk to a minimum. The PMMAD Series is available in a SO-14 package and meets the IEC
61000-4-2, IEC 61000-4-4 and IEC 61000-4-5 requirements.
