RailClamp
®
TVS diodes are specifically designed to
protect sensitive components which are connected to
high-speed data and transmission lines from overvolt-
age caused by ESD (electrostatic discharge), CDE
(cable discharge events), and EFT (electrical fast
transients).
The RClamp
®
2431T has a typical capacitance of only
0.35pF. This allows it to be used on Wi-Fi, RFID, and
other circuits operating in excess of 3GHz without
signal attenuation. It may be used to meet the ESD
immunity requirements of IEC 61000-4-2.
The RClamp2431T is in a 2-pin SLP1006P2T package
measuring 1.0 x 0.6 x 0.4mm. 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
up to 24 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 it
ideal for use in portable equipment such as cellular
phones and netbooks.
