TVS diode arrays are specifically designed
to protect sensitive components which are connected
to high-speed data and transmission lines from over-
voltage caused by ESD (electrostatic discharge), CDE
(Cable Discharge Events), and EFT (electrical fast
transients).
The unique design incorporates surge rated, low
capacitance steering diodes and a TVS diode in a
single package. During transient conditions, the
steering diodes direct the transient current through the
internal TVS diodes safely to to ground.
The RClamp
®
7512N is constructed using Semtech’s
proprietary EPD process technology. The EPD process
provides low operating voltage (2.5V) with significant
reductions in leakage current and capacitance over
silicon-avalanche diode processes. It features high
surge (Ipp=15A, tp=8/20s) and ESD (+/-25kV per IEC
61000-4-2) capability with low clamping voltage.
The RClamp7512N is in a SLP3525N12 package. It
measures 3.5 x 2.5 x 0.60mm. The leads are finished
with lead-free NiPdAu. The flow through design is
optimized for use on 2-layer pc boards. Each device
will protect up to twelve high-speed lines. The combi-
nation of small size, low capacitance, and high ESD
and surge capability makes them ideal for use in
applications such as next generation color LCD displays
and LVDS interfaces.
