Last month, the Black Shark 3 and Black Shark 3 Pro were released, becoming the world’s first 5G gaming phones. Careful users may have noticed that the Black Shark 3 is clearly equipped with a Samsung AMOLED screen, while the Black Shark 3 Pro does not name the supplier. According to Korean media reports, the Black Shark 3 Pro uses a 2.5D OLED flexible screen provided by BOE. Acc...
STMicroelectronics has introduced the ESDCAN03-2BM3Y dual automotive-qualified low-capacitance transient voltage suppressor (TVS) that protects CAN and CAN-FD interfaces. The new TVS, measuring 1.1 × 1.0 mm, can save 75 percent or more PCB space, compared to conventional TVS devices in SOT23-3L and SOT323-3L packages.
Designed to protect high-density electronic control units such as advanced driver assistance systems (ADAS), autonomous driving controllers, and automotive gateways, the ESDCAN03-2BM3Y ensures transient protection with clamping voltage as low as 33 V (8/20 µs at 1 A) and 37 V (transmission-line pulse (TLP) at 16 A). The device passes ISO 16750-2 jump-start and reversed-battery tests, withstands 15 kV ESD contact discharge (ISO 10605), and handles strong current surges with 3.3 A peak pulse rating. It is AEC-Q101 qualified.
In addition to protecting CAN and CAN-FD interfaces, the line capacitance of 3.3 pF allows the TVS to protect high-speed and high-data-rate buses such as FlexRay and USB. The minimal capacitance eases PCB design by allowing extra margin when laying out signal paths, said STMicroelectronics.
The maximum junction temperature rating of 175°C allows deployment in locations throughout the vehicle from the cabin to the engine compartment. The TVS also offers low leakage current of 50 nA at 24 V, which minimizes battery drain when the vehicle is turned off. This helps preserve the state of charge and maximize the driving range in electric-vehicle applications, said STMicroelectronics.
The ESDCAN03-2BM3Y TVS is housed in a leadless DFN1110 package with wettable flanks. Available in production quantities, prices start at $0.044 for orders of 1000 pieces.
