STU2N80K5 Description

Short technical summary and product information.

The STU2N80K5 is a single N-channel power MOSFET manufactured by STMicroelectronics. Engineered for robust high-voltage switching performance, this component operates with a maximum drain-to-source voltage of 800V and supports a continuous drain current of 2A under case temperature conditions.

 

Electrical characteristics include a maximum gate-to-source voltage of 30V and a gate threshold voltage of 5V at 100µA. The device exhibits a typical input capacitance of 105pF at 100V and a maximum gate charge of 9.5nC at 10V. At a 10V gate drive, the on-resistance remains within a maximum of 4.5 Ohms, ensuring efficient conduction during active states.

 

Thermal management is supported by a maximum power dissipation rating of 45W at case temperature. The component utilizes an IPAK surface-mount package, which provides reliable mechanical stability and thermal conductivity for industrial and consumer electronics designs. Its specifications make it suitable for motor control, power supply regulation, and general-purpose high-voltage switching circuits where compact form factors are required.
