Datasheet

Applications

Automotive controller area network where an electrostatic discharge or another
transient surge may damage the CAN transceiver or an integrated circuit (IC)
featuring a CAN PHY. This product is compliant with most of automotive interfaces.

Description

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.
