Toshiba Launches New-Generation of Transistor Arrays
Toshiba Electronics Europe has announced the launch of a new generation of highly efficient transistor arrays, the industry's first[1] with a DMOS FET[2] type source-output[3] driver. The new TBD62783A series succeeds the TD62783 series of bipolar transistor arrays, cutting power loss by about 40 percent and will find use in a wide range of applications including LED drives.
Toshiba will also launch the TBD62083A series with a DMOS FET type sink- output[4] driver, as a successor to the TD62083 series of bipolar transistor arrays for applications including motors, relays and LED drives.
Demands from customers developing systems such as power supply and ON/OFF controls that combine source output and sink output products are increasing. With the launch of these new devices, Toshiba provides a DMOS FET transistor array for both output types.
The new devices operate without a base current, reducing input currents. In combination with their ability to accept high current densities while maintaining low on-resistance, the DMOS FET devices increase efficiency and ensure reduced power losses.
All devices support high-voltage, large-current drive with absolute maximum rating of the output being 50V / 0.5A.
The devices are available in a range of packages including SOP18, DIP18 and SOL18 for surface mounted applications and SSOP18 (0.65mm pitch) to enable usage in space-constrained designs.
In order to achieve the high levels of integration seen in these devices, Toshiba has applied the latest BiCD[5] technology. The company has positioned this as the future mainstream for analog ICs fabricated on its standard 8-inch manufacturing line, the wafer size widely used in the industry for mass production.
