RCLAMP0504N Datasheet, PDF (1/9 Pages) Semtech Corporation – RailClamp® Low Capacitance TVS Diode Array
PROTECTION PRODUCTS - RailClamp
Description
RailClamps are surge rated diode arrays designed to
protect high speed data interfaces. The RClamp series
has been specifically designed to protect sensitive
components which are connected to data and trans-
mission lines from overvoltage caused by electrostatic
discharge (ESD), electrical fast transients (EFT), and
lightning.
The unique design of the RClamp series devices
incorporates eight surge rated, low capacitance steer-
ing 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 internal TVS diode prevents
over-voltage on the power line, protecting any down-
stream components.
The RClampTM0504N has a low typical capacitance of
3pF and operates with virtually no insertion loss to
1GHz. This makes the device ideal for protection of
high-speed data lines such as USB 2.0, Firewire, DVI,
and gigabit Ethernet interfaces.
The RClamp0504N is in a 6-pin, RoHS compliant,
SLP2020P6 package. It measures 2.0 x 2.0 x
0.60mm. The leads are spaced at a pitch of 0.5mm
and are finished with lead-free NiPdAu. Each device
may be used to protect four high-speed data or trans-
mission lines. They may be used to meet the ESD
immunity requirements of IEC 61000-4-2, Level 4
(±15kV air, ±8kV contact discharge).
