STMicroelectronics looks to deliver protection for high-speed interfaces
STMicroelectronicsâ ESDCAN03-2BM3Y dual automotive-qualified low-capacitance transient voltage suppressor (TVS) has been designed to protect CAN and CAN-FD interfaces.
Measuring 1.1mm x 1.0mm, the TVS meets the automotive industryâs need for highly miniaturised and high-performing protection devices for the increasing numbers of high-density ECUs (Electronic Control Units) such as ADAS (Advanced Driver Assistance Systems), autonomous driving controllers, and automotive gateways.
Using this device, designers will be able to save 75% or more of the PCB space needed by conventional TVS in SOT23-3L and SOT323-3L packages.
The ESDCAN03-2BM3Y ensures transient protection with clamping voltage as low as 33V (8/20µs at 1A) and 37V (transmission-line pulse (TLP) at 16A). Passing ISO 16750-2 jump-start and reversed-battery tests, the device has been designed to be extremely robust, withstanding 15kV ESD contact discharge (ISO 10605) and, with 3.3A peak pulse rating, able to handle strong current surges.
