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.
