Farnell is now shipping the new high-power SPDT (Single-Pole Double-Throw) RF antenna switch from Toshiba. The SPDT RF (TCWA1225G) switch is important for the expansion of 5G networks. This is because the expansion requires antennae that are increasingly composed of complex signal transmission paths that need RF switching with low insertion loss and high input power, but in a compact ...
Toshiba is aiming at industrial programmable logic controllers with fast surface-mount photocouplers that have hysteresis in the signal path. They are amplified types with threshold detection and an open-drain output. Operation is across -40 to +125°C and the secondary side will run from between 2.7 and 5.5V, consuming ~1mA. Operation is specified at 3.3 and 5V. Input-referred hysteresis is typically ...
Toshiba has announced twelve 650V silicon carbide (SiC) Schottky barrier diode (SBDs) based upon its 3rd generation technology. In this series, called TRSxxx65H, according to the company a new Schottky metal has been employed, and the junction barrier structure has been changed to lower the electric field compared with the 2nd generation to reduce leakage. Versions with nominal maximum continuous ...
Toshiba has created a range of 36V-capable LDOs to work from USB-PD and 24V power rails. The first three devices in the planned TCR1HF series, available today, are TCR1HF18B, TCR1HF33B and TCR1HF50B with fixed outputs of 1.8V, 3.3V and 5.0V respectively. Devices are in the pipeline at 2.5, 2.8, 3.0, 3.1 and 3.2V. Maximum drop-out over the -40 to 125°C ...
Toshiba has lunched a series of 600V super-junction mosfets with one that achieves 55mΩ in a 10 x 12 x 2.3mm TOLL package. TK055U60Z1 is the first of the 600V DTMOSVI series – there are already some 650V DTMOSVI parts. Rds(on) is a 13% improvement over a similar devices in its earlier DTMOSIV-H series, claimed the company, and Rds(on) x ...
Toshiba has introduced four 50V motor drive ICs that are “drop-in compatible with popular devices”, it said. The technology is BiCD, with Dmosfet output transistors. TB67S581FNG (2.5A output) and the TB67S580FNG (1.6A output) are two-phase bipolar stepping motor drivers. TB67H481FNG (PWM input) and TB67H480FNG (phase-enable inputs) are constant-current (up to 2.5A) dual H-bridge drivers for dc brushed motors or bipolar ...
Toshiba is aiming at over-temperature detection in mobile devices and home appliances with a family of ICs, intended to work with positive coefficient thermistors. Power consumption is under 12μA with 10μA of that going through the thermistor as sensing current. Lower current (<2μA) versions are planned. Inside is a current source to feed the PTC and a reference voltage with ...
Toshiba has introduced a series of multi-channel digital signal isolators that “ensuring stable high-speed digital communications even in the toughest factory floor environments”, it claims. They have 100kV/μs minimum common-mode transient immunity (1.5kV common-mode, 25°C), and carry data rates up to 150Mbit/s. Isolation is 5kV for 1 minute. Called the DCL54xx01 series, they are four-channel devices with different combinations of ...
The Toshiba board voted this morning to accept a $15.3 billion offer from a consortium led by JIP (Japan Industrial Partners) to buy the company. Toshiba will buy out other shareholders, many of them activist, and be taken private. The JIP consortium has about 20 Japanese companies in it including Orix, Rohm and Chubu Electric Power, and is backed by ...
Toshiba is aiming at 60kHz power factor correction stages with a 650V 60A reduced switching loss IGBT. “Using previous generation IGBTs, the PFC stage of air conditioners would have an operating frequency below 40kHz,” it said. The new device, GT30J65MRB, comes in a TO-3P(N) and typically dissipates 350μJ when turning off at 175°C “an improvement of at least 40% when ...
