The NUP2105L has been tested to EMI and ESD levels that exceed the specifications of popular high speed CAN networks. The Controller Area Network (CAN) is a serial communication protocol designed for providing reliable high speed data transmission in harsh environments. surge protection diodes provide a low cost solution to conducted and radiated Electromagnetic Interference (EMI) and Electrostatic Discharge (ESD) noise problems. The noise immunity level and reliability of CAN transceivers can be easily increased by adding external surge protection diodes to prevent transient voltage failures. The NUP2105L provides a surge protection solution for CAN data communication lines. The NUP2105L is a dual bidirectional surge protection device in a compact SOT-23 package. This device is based on Zener technology that optimizes the active area of a PN junction to provide robust protection against transient EMI surge voltage and CAN Physical Layer Requirements Table 1 provides a summary of the system requirements for a CAN transceiver. The ISO 11898-2 physical layer specification forms the baseline for most CAN systems. The transceiver requirements for the Honeywell(R) Smart and Rockwell Distribution Systems (SDS(R)) (Allen-Bradley) DeviceNetTM high speed CAN networks are similar to ISO 11898-2. The SDS and DeviceNet transceiver requirements are similar to ISO 11898-2; however, they include minor modifications required in an industrial environment. Table 1.

The IEC61000-4-4 Electrical Fast Transient (EFT) specification is similar to the ISO 7637-3 pulse 3a and b tests and is a requirement of SDS CAN systems. The IEC 61000-4-5 test is used to define the power absorption capacity of a surge protection device and long duration voltage transients such as lightning. Table 2 provides a summary of the ISO 7637 and IEC 61000-4-X test specifications. Table 3 provides the NUP2105L's ESD test results. The EMI protection level provided by the surge protection device can be measured using the International Organization for Standardization (ISO) 7637-2 and -3 specifications that are representative of various noise sources. The ISO 7637-2 specification is used to define the susceptibility to coupled transient noise on a 12 V power supply, while ISO 7637-3 defines the noise immunity tests for data lines. The ISO 7637 tests also verify the robustness and reliability of a design by applying the surge voltage for extended durations. The IEC 61000-4-X specifications can also be used to quantify the EMI immunity level of a CAN system. The IEC Table 2.

Surge protection Diode Protection Circuit breakdown voltage of the diode that is reversed biased, plus the diode drop of the second diode that is forwarded biased. surge protection diodes provide protection to a transceiver by clamping a surge voltage to a safe level. surge protection diodes have high impedance below and low impedance above their breakdown voltage. A surge protection Zener diode has its junction optimized to absorb the high peak energy of a transient event, while a standard Zener diode is designed and specified to clamp a steady state voltage. Figure 7 provides an example of a dual bidirectional surge protection diode array that can be used for protection with the high-speed CAN network. The bidirectional array is created from four identical Zener surge protection diodes. The clamping voltage of the composite device is equal to the CAN_H CAN Transceiver CAN_L CAN Bus NUP2105L Figure 7.
