This device is a dual-line transient voltage suppressor (TVS) specifically designed to protect the CAN H and CAN L pins of an automotive CAN transceiver against electrostatic discharge (ESD) and ISO 7637-3.


The ESDCAN03-2BM3Y complies with all the physical layer constraints (jump start, reverse polarity, …) without compromising the low clamping voltage for an efficient CAN bus protection.


The low line capacitance of each ESD diode makes this CAN protection compatible not only with CAN-FD but also with high speed and high data rate buses like FlexRay, USB and more.
