6.2.1 Detailed Design Procedure

The ESD752 has a VRWM of ±24V to protect the diode from being damaged during a short to battery event

that can occur by reversing the terminal connections during jumpstart. The bidirectional characteristic enables

signal integrity across positive and negative signal inputs, as well as accounts for any line faults or miswiring.

The low capacitance of 3pF (typical) enables data rates up to 20Mbps, which allows the designer to meet

the requirements for CAN, CANFD, CAN SiC, and CAN-XL. The clamping voltage of this device can protect

CAN transceivers with an absolute maximum rating of 58V up to the IEC61000-4-2 Level 4 standard. The 60Ω

split termination improves the electromagnetic emissions behavior of the network by filtering higher-frequency

common-mode noise that may be present on the differential signal lines.

Documentation Support section below.

7 Layout

7.1 Layout Guidelines

• The optimum placement of the device is as close to the connector as possible.

– EMI during an ESD event can couple from the trace being struck to other nearby unprotected traces,

resulting in early system failures.

– The PCB designer must minimize the possibility of EMI coupling by keeping any unprotected traces away

from the protected traces which are between the TVS and the connector.

• Route the protected traces as straight as possible.

• Eliminate any sharp corners on the protected traces between the TVS and the connector by using rounded

corners with the largest radii possible.

– Electric fields tend to build up on corners, increasing EMI coupling.

• If pin 3 is connected to ground, use a thick and short trace for this return path.

7.2 Layout Example

This example is typical of a dual channel differential data pair application, such as CAN.
