Vishay SIHK Type N-Channel MOSFET, 30 A, 650 V Enhancement, 8-Pin PowerPAK 10 x 12 SIHK085N60EF-T1GE3

This MOSFET is a high-voltage switching transistor designed for power conversion and switching applications where elevated voltage and thermal endurance are required. It is a PCB-mounted, N-channel enhancement device optimised for medium-current, high-voltage circuits in demanding thermal environments. The component conforms to RoHS directives and is intended for engineers specifying rugged discrete power transistors for industrial and power-electronics designs.

• 650V maximum drain voltage delivers wide high-voltage headroom
• 30A continuous drain current supports substantial load currents
• 0.085 Ω Rds(on) reduces conduction losses in power paths
• 184W maximum power dissipation enables sustained high-power operation
• 63 nC typical gate charge allows predictable switching-drive requirements
• Gate-source limit ±30V protects gate-drive margin during transients

• Suitable for high-voltage DC-DC converters in industrial systems
• Used for phase-leg switches in motor drive inverter stages
• Ideal for primary-side switchers in SMPS topologies
• Can be used for load switching in battery management systems
• Used with discrete power stages requiring compact package density

It is specified to operate across a broad range from -55 °C up to 150 °C, covering low-temperature starts and elevated junction conditions.

It is supplied in a PowerPAK 10x12 package optimised for PCB mounting to aid heat spreading and low-inductance layouts.

The typical 63 nC gate charge requires a driver capable of sourcing and sinking sufficient current to meet desired switching speeds while managing switching losses.

Being an N-channel enhancement device, it necessitates appropriate gate-drive polarity and is typically used on the low side or as a high-side switch with level shifting.
