X-Fab has improved 25V isolation for better SPAD integration in its 180nm XH018 fab process. 4×3 SPAD arrays: Original Isomos1 and new Isomos2 (right) SPADs – single-photon avalanche diodes – are used as optical receivers in lidar, 3D imaging, depth sensing and quantum communication. The improved isolation module, called Isomos2, improves pixel density and fill factor. “In a typical 4×3 ...

Toshiba has created a pair of highspeed photo relays for pin-switching in semiconductor test equipment. “Improved infrared LEDs and optimised photodiode arrays in these models enable switch-on times to be reduced to 150µs while maintaining signal quality,” according to distributor Rutronik, which is stocking the parts. “In addition, the S-VSON4T package saves space on the circuit board.” – it measures ...

Phlux Technology has announced 1550nm avalanche photodiode with a 3.5GHz cut-off. Part of its existing Aura range, the speed increase comes from a reduced die size, down to 30µm from 80µm (1.8GHz) or 200µm (700MHz), which drops capacitance to between 0.15 and 0.4pF. “This makes it ideal for high-speed, time-critical applications, such as those found in gigabit speed optical communications, ...

Rohm has introduced six miniature surface-mount top-view near-infrared LEDs. There are three packages: one measures 1 x 0.6mm and is only 0.2mm thick including a layer of encapsulation. Emission is 2.8mW/sr at 30mA. The other two measure 1.6 x 0.8mm and have either a lensed top (1.24mm tall, 5mW/sr at 20mA), or a flat top (1.06mm tall, 1.9mW/sr at 20mA) ...

Vishay has introduced a 5A 30V solid-state relay in a SOP-4 surface-mount  package. VOR1003M4T is an industrial-grade relay with a 1 Form A (single-pole normally-open) contact. On the output side there are back-to-back mosfets allowing ac or dc to be switched. Typical output-side figures are: 0.7Ω Rds(on), 500μs Ton, 100μsToff and <1μA leakage. These switching times are with 10mA drive ...

Toshiba has introduced an opto-isolated SiC gate driver, that includes an active Miller clamp to tame self-turn-on behaviour in the driven device. Named TLP5814H, it is a “gate driver photocoupler suitable for driving silicon carbide mosfets in industrial equipment like inverters, uninterruptible power supplies and photovoltaic inverters which experience harsh thermal environments”, according to the company. “The Miller clamp circuit ...

Vishay has created a fast opto-coupler that can operate at 25Mbit/s. Called VOIH72A, is has a digital buffering on the input and output. “The component combines a maximum pulse distortion of only 6ns, a maximum supply current of 2mA and a supply voltage range of 2.7 to 5.5V, and is fast enough to support bus systems such as SPI, as ...

Embedded World 2025: LED design is highlighted by Rutronik with its RAB5 adapter board. It features ams Osram Osire LEDs which are designed for dynamic, ambient lighting. LEDs are customisable to meet specific applications, using the manufacturer’s graphic user interface (GUI). LEDs are individually addressable chips for colour and driver selection. The LEDs can be used for interior and ambient ...

At Embedded World today, Samtec announced mid-board optical transceivers for embedded and rugged applications, including phased array radar and medical imaging. ‘Mid-board’ describes optical links that replace PCB tracks for very high speed signals. The new transceivers, branded Halo-C, are aimed at PAM4 modulated 56Gbit/s (112Gbit/s in development) per lane links with 16 channels (eight bidirectional). Read all the latest news from Embedded ...

How do you stop migrating birds from being attracted to oil rigs at night? The reasons that they should not land are two-fold: the mess that they make adds to maintenance costs, and birds that land are more likely to die before competing their journey. “Offshore platforms, such as oil and gas rigs, wind turbines, and their substations, offer a ...
