PESDXU1UT_SER_2
Product data sheet
The PESDxU1UT series is designed for protection of high-speed datalines from damage
caused by ESD and surge pulses. PESDxU1UT devices combine an ESD protection
diode and an ultra low capacitance compensation diode to ensure an effective device
capacitance as low as 0.6 pF. The PESDxU1UT series provides a surge capability of up to
200 W per line for an 8/20 s waveform.

Two PESDxU1UT devices in anti-parallel configuration provide ESD protection in a common-mode
application.
The two PESDxU1UT devices should be connected as follows:
protected data line is connected to
device 1 / pin 2
device 2 / pin 1
Ground is connected to
device 1 / pin 1
device 2 / pin 2
pin 3 is not connected for both devices
Bidirectional ESD protection of one line, common mode
Two PESDxU1UT devices in anti-parallel configuration provide ESD protection in a
differential-mode configuration as e.g. for Ethernet applications.
The two PESDxU1UT should be connected as follows:
I/O line 1 is connected to
device 1 / pin 2
device 2 / pin 1
I/O line 2 is connected to
device 1 / pin 1
device 2 / pin 2
pin 3 is not connected for both devices
Differential mode Ethernet protection
