PESD1FLEX PESD1LIN PESD1CAN PESD2CAN 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. PESD1FLEX FlexRay bus common mode choke (optional) 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.
