The SM24CANA series TVS (Transient Voltage Suppressor) Diode Array from Littelfuse is engineered to safeguard automotive Controller Area Network (CAN) lines from the damaging effects of electrostatic discharge (ESD), electrical fast transients (EFT), and other overvoltage transients. It is designed to withstand repetitive ESD strikes above the maximum level outlined in the IEC 61000-4-2 international standard without any degradation in performance, and can safely dissipate up to 3A of 8/20µs surge current as specified by IEC 61000-4-5 (2nd Edition), while maintaining very low clamping voltages.
This component is characterized by its low leakage current and low dynamic resistance, ensuring reliable protection for sensitive automotive electronics against high-energy transients. It is AEC-Q101 qualified, making it suitable for use in automotive applications, including ADAS control units, PowerTrain control units, and body control units, among others. Its robust design enables it to provide effective protection, enhancing the reliability and longevity of automotive electronics.
Arreglos de Diodos TVS
TVS Diode Arrays are semiconductor devices designed to protect electronic circuits from transient voltage spikes. Typically connected across a vulnerable signal line and ground, they work by clamping overvoltage transients to a safe level before they can damage sensitive components. TVS diodes are widely used due to their fast response time, low clamping voltage, and ability to handle high transient power.
When selecting a TVS diode, engineers should consider factors such as the working voltage, peak pulse power, clamping voltage, and package type. The working voltage should be close to the normal operating voltage of the circuit, while the peak pulse power needs to be sufficient to handle the maximum expected transient. The clamping voltage is critical as it determines the maximum voltage level that the protected components will be exposed to during a transient event.
TVS diodes are essential in applications where reliability and protection against voltage spikes are critical. They are particularly important in automotive, industrial, and telecommunications sectors, where they safeguard against ESD, EFT, and lightning-induced surges. The choice of a TVS diode should be based on the specific requirements of the application, including the nature of the transient threats, the sensitivity of the protected components, and environmental conditions.
