MOSFET from Vishay Intertechnology increases power density in mobile devices

Offering a high 37.8A continuous drain current and on resistance down to 8.4mOhm, the Vishay Siliconix SiA468DJ are offered in a compact PowerPAK SC-70 package by Vishay Intertechnology.

The 30V n-channel TrenchFET Gen IV power MOSFET delivers increased power density and efficiency for mobile devices, consumer electronics, and power supplies, says Vishay. Provided in a compact PowerPAK SC-70 package, the SiA468DJ is claimed to provide the industry’s lowest on resistance and highest continuous drain current for 30V devices in 2.0 x 2.0mm plastic packages.

The SiA468DJ is 60 per cent smaller than devices in the PowerPAK 1212. It is, says Vishay, one of the most compact 30V solutions available for DC/DC conversion and load switching for battery management in devices such as notebook computers, tablets, virtual reality (VR) headsets, and DC/DC bricks; H bridges in wireless chargers; and motor drive control for drones.

To reduce conduction loss and increase efficiency in these applications, the SiA468DJ features on resistance of just 8.4mOhm at 10V and 11.4mOhm at 4.5V. These values represent a 51 per cent improvement over previous-generation solutions, says Vishay, and a six per cent improvement over the closest competing device. In addition, the MOSFET’s low gate charge times on resistance figure of merit (FOM) is optimised for a diverse range of power conversion topologies.

The SiA468DJ’s 37.8A continuous drain current is 68 per cent higher than previous-generation devices and 50 per cent higher than the closest competing solution. This high current rating offers a safety margin for applications that encounter high transient current. The MOSFET is 100 per cent RG-tested, RoHS-compliant, and halogen-free.

Samples and production quantities of the SiA468DJ are available now.

Vishay Intertechnology manufactures discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
