Industry’s first DMOS FET transistor arrays with 1.5A sink-output driver

Toshiba has launched the TBD62064A series and TBD62308A series of highly efficient transistor arrays, featuring a DMOS FET type sink- output driver. These devices are claimed to be the industry’s first DMOS FET transistor arrays with a 1.5A sink-output driver and are suitable for used in applications including motors, relays and LED drives, such as ATMs, vending machines, slot machines, air-conditioners, office and factory automation equipment.

The 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 customer requires to reduce power loss—DMOS FET do not require a base current, and can accept high current density per device area, keeping on-resistance low. The TBD62xxxA series transistor arrays cut power loss by about 38% compared with the previous bipolar transistor series.

The products are available in DIP16 and HSOP16 packages with a heat sink that supports both high current drive and surface mounting and operate across a temperature range of -40 to 85°C.
