LOW CAPACITANCE TVS COMPONENT
DESCRIPTION
The PLW2.8 is a low capacitance, transient voltage suppressor array designed to protect applicaꢀons such as wire-
less telecommunicaꢀon devices, PCMCIA cards and portable electronics. This device is available in a unidirecꢀonal
configuraꢀon 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 protecꢀon for terꢀary type lightning threats at key interface locaꢀons.
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 configuraꢀon, this device can be subsꢀtuted for similar 0803 outlines.
