AOZ8818 Datasheet, PDF (1/8 Pages) Alpha & Omega Semiconductors – Ultra-Low Capacitance TVS Diode

AOZ8818
Ultra-Low Capacitance TVS Diode
General Description
The AOZ8818 is a transient voltage suppressor array
designed to protect high speed data lines from damaging
ESD events.
This device incorporates 16 surge rated, low capacitance
steering diodes and a TVS in a single package. During
transient conditions, the steering diodes direct the
transient to either the positive side of the power supply
line or to ground.
The AOZ8818 provides a typical capacitance of 0.3 pF
and low insertion loss up to 6GHz providing greater
signal integrity, making it ideally suited for high speed
data line applications such as Digital TVs,
DVD players, Computing, set-top boxes and MDDI
applications in mobile computing devices.
The AOZ8818 comes in a RoHS compliant and Halogen
Free 2.5 mm x 1.0 mm x 0.55 mm DFN-10 package and
is rated -40 °C to +85 °C junction temperature range.
