DMOS FET technology cuts power loss by up to 40%
Toshiba Electronics Europe has launched a new generation of highly efficient transistor arrays based on double diffused MOSFET (DMOS FET) technology. The TBD62xxxA series is both function-compatible and pin-compatible with the company’s TD62xxxA series of bipolar transistor arrays, which have found wide use in applications including motors, relays and LED drives.
The adoption of DMOS FET type output driver for the new products ensures the devices meet customer requirements for high efficiency and reduced power loss as DMOS FETs do not require a base current. ON-resistance is kept low and the output block can accept high voltages and currents, with an absolute maximum rating of 50V/0.5A.
This approach enables the TBD62xxxA series to cut power loss by about 40% compared with the preceding TD62xxxA series of bipolar transistor arrays (at 25°C and 200mA).
Toshiba has used BiCDtechnology in the creation of the series as it allows the integration of bipolar, CMOS and DMOS devices. The new generation series consists of 24 products that are compliant with various VIN(ON) standard voltages.
The TBD62003A series features min. 14V VIN(ON) to support 14 to 25V PMOS input signals. The TBD62503A series features a minimum 2.5VIN(ON) supporting transistor-transistor logic and 3/5V CMOS input signals. The TBD62004A series features a minimum 7.0VIN(ON) for 6 to 15V PMOS and 5V CMOS input signals.
The devices will be available in packages to suit a variety of needs including DIP. SOP/SOL for surface mounting and small SSOP (0.65mm pitch) for space saving. Mass production across the complete line-up is scheduled to start during the second half of 2015.
