High-Speed CANbus Protectors for Automotive and Industrial Designs



Bourns, Inc., a leading manufacturer and supplier of electronic components, today released the company’s new high-speed AEC-Q101-qualified Controller Area Network (CAN) protector. Bourns designed its latest surge protection device to protect against damage from transient voltage events such as electrostatic discharge (ESD), interruption of inductive loads or lightning strikes. Ensuring reliable high-speed communications transmission in harsh environments helps systems developers improve reliability in a broad range of automotive and industrial applications that include control networks, Smart Distribution Systems (SDS), DeviceNet™ and factory and process automation systems.

The Bourns® Model CDSOT23-T24CAN-Q (Transient Voltage Suppression) Diode Array features a dual bidirectional TVS for protecting both lines of a single CAN interface. It offers a minimum breakdown voltage of 26.2 V making it an optimal choice for transceivers with internal circuitry to protect against 24 V power supply miswiring. Meeting important international standards, Bourns’ new high-speed CANbus protectors provide ±30 kV contact discharge ESD protection per IEC 61000-4-2 and 500 V surge protection per IEC 61000-4-5 (Level 1). It comes in a SOT-23 package, and its compact size eases layout in space-constrained PCB designs while ensuring compliance with stringent EMI requirements.
