“The new SMD TOLL format helps reduce the size of equipment and the Kelvin source connection improves efficiency,” according to the company. “Measuring 9.9 x 11.68 x 2.3mm [including leads], the devices have a 27% smaller footprint than the conventional D2PAK.”
TOLL is not unique to Toshiba, Infineon, for example, is using it too. The tab is the drain, then six of the eight pins are source power connections, leaving two at one end which are the gate and the Kelvin source – the latter of which can be used to reduce parasitic inductance and transients in the gate drive loop, improving switching performance.
Inside, the mosfet is fabricated using the company’s DTMOS VI 650V super-junction technology.
Gates are tolerant to ±30V. Standard drive is +10V.
Typical applications are foreseen in server power supplies in data centres, solar photovoltaic power conditioners and UPS (uninterruptible power systems), amongst other industrial applications.
