Vishay Micro Foot TrenchFET MOSFET range

Vishay has expanded its Micro Foot TrenchFET Gen III power MOSFET family with two p-channel 30 V devices.

The Si8497DB is said to be the first 30 V chipscale MOSFET in the compact 1 x 1.5 mm size, making it the smallest available, while the Si8487DB is said to provide the lowest on-resistance available for a 30 V chipscale device in the 1.6 x 1.6 mm form factor.

The TrenchFET Gen III p-channel technology packs one billion transistor cells into each square inch of silicon.

This allows a superfine, submicron pitch process that cuts the best on-resistance for a p-channel MOSFET by up to half.

Micro Foot allows the use of a larger die for a given outline, which means a lower on-resistance for a given device area.

The devices will be used for load, battery and charger switching in handheld devices including smartphones, tablets, point-of-sale devices and mobile computing.

The devices are halogen free in accordance with the IEC 61249-2-21 definition and compliant to RoHS Directive 2002/95/EC. The Si8487DB is pin compatible with the company’s 30 V Si8409DB.
