JAJSDA2A June 2017 – August 2018 ESD122
PRODUCTION DATA.
The ESD122 is a passive circuit that triggers when voltages are above VBRF or below VBRR. During ESD events, voltages as high as ±17 kV (contact) can be directed to ground via the internal diode network. When the voltages on the protected line fall below the trigger levels of ESD122 (usually within 10s of nano-seconds) the device reverts to passive.
Figure 12 shows typical TLP behavior of bi-directional ESD device.
