High-Speed Interface Protection Provided by STMicroelectronics' Low-Capacitance Transient Voltage Suppressor for Automotive Applications

The automotive industry has a new addition to its arsenal of protection devices, the ESDCAN03-2BM3Y TVS, manufactured by Vishay. This latest offering has been designed to meet the needs for miniaturized and high-performing protection devices in the automotive industry, particularly for high-density ECUs like ADAS, autonomous driving controllers, and automotive gateways.

The ESDCAN03-2BM3Y TVS has passed the ISO 16750-2 jump-start and reversed-battery tests, demonstrating its robustness. It is capable of protecting high-speed and high-data-rate buses such as FlexRayTM and USB, thanks to its line capacitance of just 3.3pF. This makes it an ideal choice for modern vehicles that rely on these buses for their advanced features.

One of the standout features of the ESDCAN03-2BM3Y TVS is its minimal capacitance, which eases PCB design by allowing extra margin when laying out signal paths. It also minimizes battery drain when the vehicle is turned off, helping to preserve the state of charge and maximize the driving range in electric-vehicle (EV) applications.

The device offers outstanding transient protection with a clamping voltage as low as 33V (8/20μs at 1A) and 37V (transmission-line pulse (TLP) at 16A). It can withstand 15kV ESD contact discharge (ISO 10605) and has a 3.3A peak pulse rating, enabling it to handle strong current surges.

The DFN1110 package of the ESDCAN03-2BM3Y TVS has wettable flanks that facilitate high-speed automatic optical inspection after soldering. This makes it easier for manufacturers to integrate the device into their production processes.

The ESDCAN03-2BM3Y TVS, like its counterpart the ESDCAN03-TVS, offers protection for advanced driver assistance systems (ADAS), autonomous driving controllers, and automotive gateways. It is manufactured to fulfil high-quality assurance targets, ensuring that it meets the stringent requirements of the automotive industry.

Prices for the ESDCAN03-2BM3Y TVS start at $0.044 for orders of 1000 pieces. For more information, visit www.st.com.

The ESDCAN03-2BM3Y TVS can be deployed in various vehicle locations, including the cabin and engine compartment, due to its high temperature rating. It has a maximum junction temperature rating of 175°C, making it suitable for use in a wide range of automotive environments.

With its robustness, minimal capacitance, and high-speed automatic optical inspection capabilities, the ESDCAN03-2BM3Y TVS is set to become a valuable addition to the automotive industry's toolkit. Its ability to save 75% or more of the PCB space needed by conventional TVS in SOT23-3L and SOT323-3L packages makes it an attractive choice for manufacturers looking to reduce the size and weight of their ECUs.
