Description
The HSP181-2W3Y is an ESD array designed for high-speed differential lines. The
VRM at 18 V makes it compatible with a short-to-battery hazard in vehicles.
The HSP181-2W3Y is also compatible with the maximum signal voltage (18 V) on
the antenna of NFC readers and can thus efficiently protect NFC antenna I/O of NFC
ICs.
The 2.1 pF low parasitic capacitance and the 1.7 GHz bandwidth provides enough
room to preserve the signal integrity of USB 2.0 or NFC signals.
The HSP181-2W3Y is housed in SOT323-3L.

Application
• USB 1.1 and USB2.0
• NFC
• Other high speed signals
