The ESD2CAN24-Q1 is an Automotive Dual 3pF, ±24V, ±30kV ESD Protection Diode for CAN and In-Vehicle Networking
The ESD2CAN24-Q1 is a bidirectional ESD protection diode for APX321SEG-7 Controller Area Network (CAN) interface protection. The rated contact ESD strike dissipation of the ESD2CAN24-Q1 exceeds the maximum levels specified in the ISO 10605 automotive standard (±30kV contact, ±30kV air gap). Low dynamic resistance and low clamping voltage ensure system-level protection from transient events. This protection is key because automotive systems require a high level of robustness and reliability for safety applications.
The device features low IO capacitance per channel and a pinout to accommodate two automotive CAN buses (CANH and CANL) against damage from electrostatic discharge (ESD) and other transients. Additionally, the 3 pF line capacitance of the ESD2CAN24-Q1 is suitable for CAN, CANFD, CAN SiC and CAN-XL applications that can support data rates up to 10 Mbps.
The ESD2CAN24-Q1 is available in a two-lead package for easy routing.
