Osram has created an optical time-of-flight sensor with a 48 x 32 pixel receiving array that builds up a 1,536 point depth map as wide as 80° and at ranges from 10mm to 11m. “It is designed to detect subtle spatial differences and distinguish closely spaced or slightly varied objects. [It] can tell whether an espresso cup or a travel ...

Toshiba has squeezed a photo relay with 1,500V output mosfets into an 8 x 10mm surface-mount package. TLX9161T is aimed at electric vehicle batteries, and turns on or off in a maximum of 1ms. Its characteristics are tuned for “modern automotive battery and fuel-cell control and battery management systems, which monitor voltage and detect mechanical relay sticking and ground faults”, ...

Osram has created a 265nm UV-C emitting LED with 10.2% wall-plug efficiency at 200mW radiant flux, and a lifespan exceeding 20,000 hours. “With these specifications, it can replace conventional mercury discharge lamps in the future,” according to the company, whose previous best LED coul only manage 5.3%. The increase in efficiency is attributed to optimising the extraction of UV-C from ...

Toshiba is aiming at 800V electric vehicles with an SO16 photo-relay with 1.8kV output mosfets. “Photo-relays commonly used in battery systems must withstand a voltage of approximately twice the system voltage, therefore, an output withstand voltage of over 1,600V is required for an 800V system,” according to the company. “Toshiba’s TLX9165T meets and exceeds this requirement.” The high-voltage mosfets inside ...

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 ...
