PLW2.8
LOW CAPACITANCE TVS COMPONENT
DESCRIPTION
The PLW2.8 is a low capacitance, transient voltage suppressor array designed to protect applications such as wire-
less telecommunication devices, PCMCIA cards and portable electronics. This device is available in a unidirectional
configuration with a working voltage of 2.8V and a minimum breakdown voltage of 3.0V. The PLW2.8 is rated at 50W
peak pulse power (8/20µs), which is sufficient protection for tertiary type lightning threats at key interface locations.
The PLW2.8 is ideally suited to protect data I/O ports against ESD. This device meets the requirements of IEC 61000-2.
Packaged in a SC-79 configuration, this device can be substituted for similar 0803 outlines.
