Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. 1. Nonrepetitive current pulse per Figure 1.

APPLICATIONS SECTION
The NUP1105L provides a transient voltage suppression solution for the LIN data communication bus. The NUP1105L is a dual bidirectional TVS 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 ESD. The NUP1105L has been tested to EMI and ESD levels that exceed the specifications of popular high speed LIN networks.
The NUP1105L device can be used to provide transcient voltage suppression for a single data line CAN system. Figure 7 provides an example of a single data line CAN protection circuit.
