To provide higher efficiency and power density for telecom, industrial and computing applications, Vishay Intertechnology, Inc. has introduced a new 150 V TrenchFET Gen V n-channel power metal-oxide semiconductor field-effect transistor (MOSFET) in the PowerPAK SO-8S (QFN 6x5) package.
Compared to previous-generation devices in the PowerPAK SO-8, the Vishay Siliconix SiRS5700DP slashes overall on-resistance by 68.3% and on-resistance times gate charge — a key figure of merit (FOM) for MOSFETs used in power conversion applications — by 15.4%, while providing 62.5% lower junction-to-case thermal resistance (RthJC) and 179% higher continuous drain current.
With the industry’s lowest on-resistance of 5.6 mW at 10 V and on-resistance times gate charge FOM of 336
Source: Vishay Intertechnology, Inc. mW nC, the device released today minimizes power losses from conduction. This allows designers to boost efficiency to meet next-generation power supply requirements, such as 6 kW artificial intelligence server power systems. In addition, the extremely low 0.45° C/W RthJC of the PowerPAK SO-8S package enables continuous drain current up to 144 A to increase power density, while providing robust SOA capability.
The SiRS5700DP is ideal for synchronous rectification, DC/DC converters, hot swap switching and OR-ing functionality. Typical applications will include servers, edge computing, super computers and data storage; telecom power supplies; solar inverters; motor drives and power tools; and battery management systems. RoHS-compliant and halogen-free, the MOSFET is 100% Rg and UIS tested and complies with IPC-9701 criteria for more reliable temperature cycling. The device’s standard 6 mm by 5 mm footprint is fully compatible with the PowerPAK SO-8 package.
Samples and production quantities of the SiRS5700DP are available now.
