Industry’s first transistor arrays with DMOS FET source-output driver

Toshiba has launched the TBD62783A series of highly efficient transistor arrays, said to be the industry’s first with a DMOS FET type source-output driver. This series succeeds the TD62783 series of bipolar transistor arrays, claimed to cut power loss by around 40% and is suitable for a range of applications including LED drives.

Toshiba is also launching the TBD62083A series with a DMOS FET type sink- output driver, as a successor to the TD62083 series of bipolar transistor arrays for applications including motors, relays and LED drives.

The new devices are said to 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 to enable usage in space-constrained designs.
