Rail-to-rail clamp for USB 2.0 and Ethernet
Its 1.5 pF capacitance at 1 MHz keeps the eye diagram clean on USB 2.0 (480 Mbps) and 10/100 Ethernet differential pairs — a common pain point where higher-capacitance TVS arrays distort the signal edge and fail compliance.
1.5 pF — why it matters for the signal budget
At 1.5 pF per channel, this part adds roughly 0.5 dB of insertion loss at 480 MHz — negligible for USB 2.0. The rail-to-rail steering topology steers the ESD current to VCC and GND rather than shunting it through a dedicated avalanche diode, which keeps the clamping voltage symmetrical and the residual energy off the transceiver pins.
Active and rated for industrial heat
The SC-70-3 package (SOT-323 footprint) fits tight PCB layouts; the two channels share a common ground pin, so the routing is straightforward for a single differential pair.
