The Renesas 2SK3814 is an N-channel power MOSFET designed for high-current switching applications. It features a maximum drain-source voltage of 60 V and a continuous drain current of 60 A at 25°C case temperature. The device offers super low on-state resistance, with RDS(on)1 max 8.7 mΩ at VGS=10V and RDS(on)2 max 10.5 mΩ at VGS=4.5V, both tested at ID=30A. Input capacitance is typically 5450 pF. It supports a single avalanche energy of 102 mJ and operates up to a channel temperature of 150°C.
Verify the specific package variant required (TO-251 or TO-252) against your board layout constraints before ordering. Confirm that the component quality grade meets your application's safety requirements. Ensure thermal management designs account for the specified total power dissipation limits at expected operating temperatures. Check for any recent product change notices regarding manufacturing updates.
Select this component when designing circuits requiring robust N-channel switching with low conduction losses. Consider the gate charge characteristics for driving efficiency in high-frequency applications. Evaluate the thermal resistance values to ensure adequate heat sinking for the intended duty cycle. Verify compatibility with available gate drive voltages for optimal RDS(on) performance.
