As a leading domestic manufacturer in the ESD protection field, Leiditech has provided mature and comprehensive domestic alternative solutions for Nexperia's product line, especially in the areas of LIN, CAN(FD), and FlexRay vehicle network interfaces. In terms of alternative selection, Leiditech's products not only strictly match the industry standards in key parameters but also ensure stable and reliable supply. Currently, many of its ESD protection devices have been widely adopted by customers and have demonstrated outstanding cost-performance advantages after batch verification, while maintaining consistent performance. 

The common ESD diode replacement models for Nexperia's LIN/CAN(FD)/FlexRay bus are listed in Table 1 as follows:：

Table 1 

If you are looking for an alternative to Nexperia's static diodes, you can contact the sales staff of Shanghai Lebao. 

To determine whether an ESD diode can be used as a substitute, the following points should be considered: 

1) Is VRWM close? 

2) Is the anti-static performance comparable? 

3) Is VBR close? 

4) Is IPP close? 

5) Is CJ close? 

Below, a comparison of several alternative model parameters for Reliance Semiconductor will be presented. 

1. LIN Bus Electrostatic Protection Scheme and Domestic Alternatives 

LIN (Local Interconnect Network) bus is a low-cost serial communication network used to achieve distributed electronic system control in automobiles. LIN bus is a supplement to other automotive multi-networks such as Controller Area Network (CAN), and is suitable for applications where there are no high requirements for network bandwidth, performance, or fault-tolerant functions.

By comparing, the parameter performance of Zhilema PESD1LIN is superior to that of Nexperia's PESD1LIN.

2、 CAN(FD)/FlexRayBus static protection scheme and domestic alternatives

The CAN (FD)/FlexRay bus requires an effective protection scheme to prevent electrostatic discharge (ESD) and surge interference, ensuring the reliability and stability of communication. The protection scheme diagram for Shanghai Lebao CAN (FD) is as follows.：

The above scheme uses Shanghai Lebao's SMC24LVQ, SMC27LVQ and SMC36LVQ for protection. The reason for having three options is that customers can choose to use them based on the working voltage. 

Domestic alternative for CAN(FD)/FlexRay bus 

According to the Nexperia model listed in Table 1, the parameters of each model vary slightly. The table presents a detailed comparison of the parameters between the domestic alternative models for Rebo and these models:

3、 Application fields

The LIN, CAN(FD) and FlexRay bus ESD protection devices are the "safety guards" of modern automotive electronic systems. They are widely used in various fields such as vehicle body control (like windows, door locks, and lights), powertrain (engine and transmission control), chassis safety (ABS, airbags), and intelligent driving (radar, cameras). In the vehicle network, these sophisticated chips are highly susceptible to electrostatic discharge, which can cause communication interruptions or hardware damage. Shanghai Lebao's dedicated ESD protection devices ensure the integrity of bus signals and system reliability by providing precise voltage clamping and high-speed energy dissipation. With the development of automotive intelligence, low-capacitance and high-strength protection devices that comply with the AEC-Q101 standard have become indispensable key components for ensuring the stable operation of vehicle network communications.
