➀ Toshiba has released a high-speed low-voltage photo-relay suitable for the pin electronics of semiconductor testers; ➁ The turn-on switching time is below 80μs, representing a 40% improvement over the previous generation; ➂ The device features a single normally-open contact, continuous output rating of 20V and 160mA, and an isolation of at least 500Vrms.

➀ Kioxia is set to receive approval for its listing on the Tokyo Stock Exchange at a valuation of $4.84 billion. The company's valuation has dropped sharply from its previous cancelled IPO in October, where it was seeking a valuation of $10.3 billion.➁ Kioxia has faced various offers and acquisitions over the years, including a $30 billion offer from Foxconn in 2017, a $18 billion acquisition by a Bain-led consortium in 2018, and a $20 billion offer from Western Digital in 2022.➂ The Bain consortium owns 56% of Kioxia, Toshiba owns 41%, and the Japanese government bail-out funds INCJ and DBJ control 16.7% of the voting rights.

➀ Toshiba has been taken private; ➁ Led by Japan Industrial Partners; ➂ Recent transaction

➀ Kioxia, the third-largest manufacturer of NAND flash, has seen its valuation drop from $30 billion to $5 billion over the past seven years. Initial bids for Toshiba's memory business reached $30 billion, but the current market value is significantly lower. ➁ Toshiba's memory unit was previously owned by a Bain-led consortium that included Hynix, Apple, Dell, Kingston, and Seagate. ➂ With the latest valuation of $5 billion, Toshiba could potentially re-integrate its former memory unit at a low price.

➀ Toshiba has introduced ten 1.2kV silicon carbide Schottky diodes; ➁ Half are in TO-247-2L packaging and half in TO-247; ➂ The diodes have a forward voltage of typically 1.27V and can handle high currents.

➀ Toshiba has developed a pair of 32Gbit/s multiplexer/demultiplexer switches for high-speed serial busses like PCIe 5.0/4.0, USB4, and Thunderbolt 4; ➁ The devices are designed to switch differential pair or single-ended signal paths between single and double ports; ➂ The switches are made on Toshiba's 'TaRFSOI' process and offer different specifications for board layout and high-frequency performance.

➀ Toshiba has launched a 5kW Isolated Bidirectional DC-DC Converter reference design using SiC MOSFETs and DAB topology for high-power applications like electric vehicle charging and solar inverters; ➁ The DAB topology allows for bidirectional high-power conversion with full bridges on both sides, enhancing efficiency and power handling; ➂ SiC MOSFETs are used to achieve high power conversion and efficiency levels, operating at higher switching frequencies than traditional IGBTs.

➀ Toshiba is developing an interface IC for the automotive CXPI bus, which integrates GPIO, ADC, and PWM functionalities. ➁ The TB9033FTG IC features 16 GPIO pins, with six supporting a 10bit ADC and four capable of PWM outputs with 8bit resolution. ➂ The IC also includes a 4×4 switch matrix mode and fault detection for over-temperature, over-voltage, and low-voltage conditions.

➀ Toshiba introduces the TPD4165K, a 3A brush-less DC motor driver with a 600V maximum input voltage, aimed at air conditioners, air purifiers, and pumps. ➁ The device features a six IGBT three-phase bridge and supports three-shunt or single-shunt current sensing. ➂ It includes protections such as over-current, under-voltage, and thermal shut-down, and is packaged in a smaller HDIP30 package.

➀ Farnell is now shipping Toshiba's high-power SPDT RF antenna switch, crucial for 5G network expansion. ➁ The TCWA1225G switch offers 46 dBm peak input power in a compact design, supporting complex signal paths without increasing antenna size. ➂ Toshiba's SPDT RF switch addresses the need for low insertion loss and high input power in massive MIMO technology, essential for 5G telecommunications.

➀ Toshiba has released a 700MHz to 5GHz single-pole, double-throw antenna switch in a 1.9 x 1.9mm WCSP package. ➁ The device offers an input peak power of 46dBm and reduces insertion loss to 0.6dB at 5GHz. ➂ It is designed for applications in massive MIMO antennas in 5G installations, industrial equipment, and repeaters.
