esdr0502n http://onsemi.com 4 application information protecting usb 2.0 interfaces the usb interface consists of data (d ? and d+) lines and a 5.5 v bus, which are all vulnerable to esd and cable discharge events. each esdr0502n device will protect the four usb connections (v cc , d+, d ? , and gnd) of one usb port. when the voltage on the data lines exceed the bus voltage (plus one diode drop), the internal rectifiers are forward biased conducting the transient current away from the protected controller chip. the tvs diode suppresses esd strikes directly on the voltage bus and directs the surge to ground, protecting both the power and data pins. 1 2 3 6 5 4 vbus d+ d ? gnd d+ d ? esdr0502n usb connector usb controller figure 6.
