ESD protection diodes
for automotive applications
Protecting an Electronic Control Unit (ECU) against ElectroStatic Discharge (ESD) and other transient
pulses is one of the most important ways to reduce failures in automotive applications. These pulses
can enter the ECU via the battery line as well as the data bus lines.
NXP Semiconductors offers a series of ESD protection diodes designed to protect FlexRay bus
transceivers, Local Interconnect Network (LIN) and Controller Area Network (CAN) as well as other
ESD sensitive automotive electronic components.
All these devices deliver MIL-STD-883 class 3-compliant human body protection and meet the
IEC 61000-4-2 (air and contact discharge) and IEC 61000-4-5 standards.

FlexRay bus protection
The PESD1FLEX protects two automotive FlexRay data lines
from the damage caused by ESD and other transients.
It supports the FlexRay data rate of 10 Mbit/s and provides
a surge capability of up to 200 W per line for an 8/20 μs
waveform.

PESD1LIN
Local Interconnect Network (LIN) bus protection
The PESD1LIN protects one automotive LIN bus line
from the damage caused by ESD and other transients. Its
asymmetrical internal diode configuration ensures optimized
electromagnetic immunity for the protected LIN ECU.
Key features
}bidirectional protection for one LIN bus line in a very
small SOD323 (SC-76) SMD plastic package
}max. peak pulse power: PPP = 160 W at tp = 8/20 µs
}low clamping voltage: V(CL)R = 40 V at IPP = 1 A
}ultra low leakage current: IRM < 1 nA
}ESD protection up to 23 kV

PESD1CAN and PESD2CAN
Controller Area Network (CAN) bus protection
The PESD1CAN and PESD2CAN protect two automotive
CAN bus lines from the damage caused by ESD and other
transients. They can be used with both high-speed and
fault-tolerant CAN buses.
