PMAD Series

ultRA low cAPAcitAnce Multi-line SteeRing DioDe ARRAy

DeScRiPtion

The PMAD 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

PMAD 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 PMAD Series is available in a 14 pin DIP and meets the IEC

61000-4-2, IEC 61000-4-4 and IEC 61000-4-5 requirements.
