Electronic fuse covers 8-48V and up to 4A.

STEF01 is an 8-48V 4A programmable electronic fuse from STMicroelectronics. When connected in series to the main power rail, it protects the load against over-current and over-voltage. Voltage is clamped to a user-defined maximum, preset with external resistors. Excessive current is restricted to the programmed safe limit by controlling the internal power mosfet, and folds-back ...

Shottky for back-flow protection leaks and heats less

Toshiba has launched a Schottky barrier diode aimed at rectification and back-flow prevention. Called CUHS10F60, due to the newly developed 2.5 x 1.4mm US2H package (SOD-323HE) it features a thermal resistance of 105°C/W. “The package’s thermal resistance has been reduced by about 50% compared to the conventional USC package,” said the firm. In comparison to Toshiba’s earlier ...

Boron arsenide thermal record – the second in a week

Close on the heels of a US heat-sinking record using the synthetic material boron arsenide, comes a second record using the same material, this time from scientists at University of California, Los Angeles. The material is being mooted as a high-performance heat-spreader – drawing heat away from hot spots in high-power electronics and photonics. The ...

Ru breakthrough for 3nm interconnect

Ruthenium (Ru) could be an  interconnect material for 3nm and beyond technology nodes, reports Imec. High-aspect ratio Ru lines have been shown to outperform conventional Cu metallization in two different implementation scenarios, i.e., (1) in buried power rail applications, and (2) as interconnects for advanced memory and logic applications by using subtractive metal etch. Due ...
