80V MOSFET offers best in class RDSon, says Vishay
An 80V TrenchFET Gen IV n-channel power MOSFET from Vishay Intertechnology is supplied in the 6.15 x 5.15mm PowerPAK SO-8 single package. The Vishay Siliconix SiR680ADP is designed to save energy by increasing the efficiency of power conversion topologies and switching circuitry, It is claimed to offer best in class on-resistance times gate charge of 129 mOhm*nC.
The SiR680ADP combines on-resistance down to 2.35 mOhm typical at 10V with low gate charge of 55nC and output capacitance (COSS) of 614pF. These specifications are fine-tuned to reduce the power losses from switching, channel conduction, and diode conduction, resulting in increased efficiency, says Vishay. The MOSFET’s on-resistance times gate charge figure of merit (FOM) is 12.2 per cent lower than the closest competing product and 22.5 per cent lower than the previous-generation device, claims Vishay, making it the most efficient solution available for typical 48V input to 12V output DC/DC converters.
The SiR680ADP will serve as a building block in a variety of DC/DC and AC/DC conversion applications such as synchronous rectification, primary-side switching, buck-boost converters, resonant tank switching converters, and the OR-ing function in systems such as telecomms and data centre server power supplies, solar micro-inverters, battery switching in battery management modules and motor drive control in power tools and industrial equipment.
The MOSFET is 100 per cent RG- and UIS-tested, RoHS-compliant, and halogen-free.
Samples and production quantities of the SiR680ADP are available now, with lead times of 12 weeks.
Vishay Intertechnology is a manufacturer of discrete semiconductors (diodes, MOSFETs and infra red optoelectronics) and passive electronic components (resistors, inductors and capacitors). These components are used in virtually all types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets, says Vishay.
