Toshiba starts mass production of new transistor arrays

Toshiba Corporation's Semiconductor & Storage Products Company has started mass production of its new line-up of highly efficient TBD62064A and TBD62308A series of transistor arrays. The new additions are fitted with DMOS FET type sink- output driver and offered in standard 1mm- pitch type "SSOP24" surface-mount packaging without heat radiating fins. This makes them suitable for board mounting.

The new products are equipped with 4 channels of 50V/1.5A rated output, suitable for driving constant voltage unipolar stepping motors.

Toshiba adopted DMOS FET output drivers for its new products to secure the high efficiency required to reduce power loss—DMOS FETs do not require a base current, and can accept high current density per device area, keeping on-resistance low.

The line-up includes DIP packages, where there is strong demand from the hobby goods, amusement and industrial equipment fields, and SSOP/HSOP packages that support high current (1.5A) drives and surface mounting.

Applications include amusement equipment (pachinko and slot machines), home appliances (air conditioners and refrigerators) and industrial equipment (vending machines, banking terminals such as ATMs, office automation equipment, and factory automation equipment).
