RCLAMP1521PQ Datasheet, PDF (1/9 Pages) Semtech Corporation – Ultra-Low Capacitance 1-Line ESD protection
PROTECTION PRODUCTS - RailClamp®
Description
The RailClamp family is a series of ultra low capacitance
Transient Voltage Suppressors (TVS) designed to protect
high speed data interfaces. This series has been specifi-
cally designed to protect sensitive components which
are connected to high-speed data and transmission
lines from overvoltage caused by ESD (electrostatic dis-
charge), CDE (Cable Discharge Events), and EFT (electri-
cal fast transients).
The RClamp®1521PQ has a maximum capacitance of
only 0.5pF. This allows it to be used on circuits operat-
ing in excess of 3GHz without signal attenuation. They
may be used to meet the ESD immunity requirements of
IEC 61000-4-2, Level 4 (±15kV air, ±8kV contact dis-
charge).
The RClamp1521PQ is in a 2-pin, RoHS/WEEE compli-
ant, SLP1006P2 package measuring 1.0 x 0.6 x 0.5mm.
The leads are spaced at a pitch of 0.65mm and feature
a lead-free finish. Each device will protect one high-
speed line operating at 15 volts. It gives the designer
the flexibility to protect single lines in applications where
arrays are not practical. The combination of small size,
low capacitance, and high ESD surge capability makes
them ideal for use in applications such as cellular
phones and high-power USB.
The RClamp1521PQ is qualified to AEC-Q100 Grade 1
for Automotive use.
