Vishay VOT8026A, VOT8123A Optocoupler, Phototriac Output

Vishay broadened its optoelectronics portfolio with the release of two new series of optocouplers with phototriac output in compact DIP-6 and SMD-6 packages. Offering high off-state voltage of 800 V and static dV/dt of 1000 V/μs, the Vishay Semiconductors VOT8026A and VOT8123A deliver high robustness and noise isolation for home appliances and industrial equipment.
The optocouplers announced today isolate low voltage logic from 120 VAC, 240 VAC, and 380 VAC lines to control resistive, inductive, or capacitive loads, including motors, solenoids, high current thyristors, or TRIACs and relays. Reducing design costs and saving board space, the devices consist of a GaAs infrared LED optically coupled to either a zero-crossing TRIAC (VOT8026A) for EMI reduction without the need for external snubber networks, or a random-phase TRIAC (VOT8123A) to enable phase-independent switching.

The high off-state voltage of the VOT8026A and VOT8123A enhances safety margins in one-phase applications, while still maintaining enough voltage headroom for three-phase applications. For additional safety, the optocouplers offer a withstanding isolation voltage of at least 5000 VRMS. Low trigger currents of 5 mA for the VOT8026A and 10 mA for the VOT8123A facilitate an easy interface with digital logic.

Microchip New SAMV71Q21RT, SAMRH71 Radiation-Tolerant and Radiation-Hardened Arm® MCU

Microchip introduced the space industry’s first Arm®-based microcontrollers (MCUs) that combine the low-cost and large ecosystem benefits of Commercial Off-the-Shelf (COTS) technology with space-qualified versions that have scalable levels of radiation performance. Based on the automotive-qualified SAMV71, the SAMV71Q21RT radiation-tolerant and SAMRH71 radiation-hardened MCUs implement the widely deployed Arm® Cortex®-M7 System on Chip (SoC), enabling more integration, cost reduction and higher performance in space systems. SAMV71Q21RT is the radiation tolerant version of the popular Microchip SAMV71Q21. This space-qualified version of the product adds:  Ceramic & hermetic package, extended temperature range -40C to 125C, extended qualification flow according to QML-V or QML-Q space grade flow.  Radiation performance for the SAMV71Q21RT:  SEL LET > 60 MeV.cm2/mg (at 125C), and TID up to 20 Krad (Si). SAMRH71 is the Radiation-Hardened-By-Design (RHBD) version of...
