TOKYO — (BUSINESS WIRE) — December 17, 2015 — Toshiba Corporation's (TOKYO:6502) Semiconductor & Storage Products Company today announced the launch of a new generation of highly efficient transistor arrays, the TBD62064A series and TBD62308A series, with a DMOS FET type sink- output driver. The new series succeed the TD62064A series and TD62308A series of bipolar transistor arrays that found wide use in applications including motors, relays and LED drives, and are the industry’s first DMOS FET transistor arrays with a 1.5A sink-output driver.

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.
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 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.
Main Features of New Products
- High efficiency drive
TBD62xxxA series transistor arrays cut power loss by about 38% compared with the TD62xxxA series.
- High-voltage, large-current drive
The absolute maximum output rating is 50V/1.5A.
- Packages to suit various needs.
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 realizes both high current(1.5A) drive and surface mounting.
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)
