Vishay has unveiled its latest 650V super-junction MOSFET, claiming the industry's lowest Rds(on)•Qg and Rds(on)•Co(er) figures-of-merit. 

The SiHK050N65E delivers typical values of 3.74ΩnC and 8ΩpF, setting a new benchmark in power efficiency and performance.

High-Performance Power Conversion Solution

The SiHK050N65E is an N-channel MOSFET specifically designed for power factor correction (PFC) and high-efficiency DC-DC conversion, supporting power levels of up to 6kW. Key specifications include:

• On-resistance (Rds(on)): 48mΩ (at 25°C, 10Vgs)

• Gate charge (Qg): 78nC (16A, 520V, 10Vgs)

Enhanced Efficiency and Robust Design

Optimized for 200–277Vac inputs, the SiHK050N65E aligns with the Open Compute Project’s ORV3 standard. It enables power supply designs to meet titanium efficiency requirements, helping server power supplies achieve up to 96% peak efficiency. Additionally, the MOSFET is designed to withstand overvoltage transients in avalanche mode, with 100% UIS testing ensuring reliable operation under harsh conditions.

Superior Hard-Switching Capabilities

For applications involving hard switching, such as PFC stages and two-switch forward converters, the device features:

• Effective output capacitance (Co(er)): 167pF

• Effective output capacitance (Co(tr)): 1.119nF

These characteristics contribute to low switching losses and enhanced system efficiency.

Advanced Packaging and Design Benefits

The SiHK050N65E is housed in a compact 10 x 12mm surface-mount TOLL package, which provides improved thermal performance and ease of integration. Additionally, the inclusion of a Kelvin connection ensures better gate drive control, reducing switching losses and enhancing overall efficiency.
