Toshiba Corp.'s Semiconductor & Storage Products Co. has rolled out what it says are highly efficient transistor arrays with a DMOS FET type sink- output driver. The TBD62064A series and TBD62308A series succeed the TD62064A series and TD62308A series of bipolar transistor arrays that found broad applications such as motors, relays and LED drives, and are the industry's first DMOS FET transistor arrays with a 1.5A sink-output driver, stated the company.

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

TBD62064A series

Toshiba adopted DMOS FET output drivers for its latest 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.

According to the company, the TBD62xxxA series transistor arrays cut power loss by about 38 per cent compared with the TD62xxxA series and features an absolute maximum output rating of 50V/1.5A. In addition, the line-ups include a DIP type, strongly demanded by the equipment market for hobbies, amusements and industrial fields, and an HSOP type with a heat sink that realises both high current drive and surface mounting.

Applications of the devices 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).

Mass production of TBD62064A series products is scheduled to start in February 2016. Sample shipments of TBD62308A series products start today, with mass production slated for March 2016.
