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 ...

Toshiba has introduced a set of industrial-grade 650V SiC mosfets in 8 x 8mm DFN packaging. Of the four new devices, the company picks TW054V65C as its poster child for low turn-on and turn-off losses: 122 ad 58μJ respectively when a pair are used in a 400V 20A half-bridge* – said to be ~55% and 25% less than the company’s ...

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 ...

Toshiba has introduced some 50Mbit/s four-channel automotive high-speed digital isolators for digital signals. It is the DCM34xx01 series, and it has been designed to typically provide 100kV/μs common-mode transient immunity, in electric vehicle on-board chargers and battery management systems. Depending on the exact part, there can be: Four forward channels Three forward and one reverse Two forward and two reverse ...

Toshiba has announced a 1.2kWh 27.6Vdc li-ion battery module for electric buses, ships and boats. Called Type4-23 (also FM01202CCB04A), it is electrically similar to the company’s existing Type1-23 in that it is 2P12S (24 cells in two parallel 12 series arrangement) module, but the earlier versions resin baseplate has been replaced by aluminium to improve heat extraction. “When used with ...

Toshiba has announced a 600V super-junction mosfet with a maximum on-resistance of 24mΩ in a TO-247 package (20mΩ typ). Typical gate-drain charge is 37nC (400Vd, 10Vg, 80A) and total gate charge (gate-source + gate-drain) is 140nC. Reverse recovery for the intrinsic diode is 8.5µC and 425ns, both at 400V, 40A, 100A/µs and Vg=0 . “TK024N60Z1 uses the DTMOSVI 600V process ...

Toshiba Electronics has introduced a 60V 1A single-contact photo-relay in a 2.6 x 7mm 4pad SO4 package. Called TLP3640A, it can switch 60Vdc or 60Vac peak, with a typical on-resistance of 0.14Ω and maximum off-state leakage of 1µA. 100ms pulses of up to 3A can be carried. Operation is over -40 to +110°C, and de-rating starts at 25°C, dropping linearly ...

Toshiba is aiming at 400V automotive systems with a 400V photo-relay that can handle 900V and ~30mA. Recommended maximum operating voltage is 720V. Called TLX9150M, it measures around 10 x 8 x 2.5mm and can carry 50mA at 25ºC, 20mA at 105ºC and 10mA at 125ºC, or 1ms pulses of 150, 60 and 30mA respectively. The package, SO12L-T has 8mm ...

Toshiba is aiming vehicle body automation with it its latest three-phase motor diver. TB9084FTG, as it will be known “supports replacing brushed dc motors with quieter, longer-lasting BLDC motors to drive body system applications like powered sliding passenger doors, power tailgates, adjustable seats, electric pumps and fans”, it said. The IC is designed to control the gates of seven external ...

Toshiba has released a “high-speed” low-voltage photo-relay “particularly suitable for the pin electronics of semiconductor testers”, it said. High-speed? “Turn-on switching time is below 80μs,” according to Toshiba. “Compared to the previous generation – TLP3450 – this represents a 40% improvement.” It has a single normally-open ‘contact’, consisting of back-to-back mosfets making it suitable for switching ac or dc signals. ...
