STL4LN80K5 Description

Short technical summary and product information.

The STL4LN80K5 is an N-Channel enhancement-mode power MOSFET manufactured by STMicroelectronics using MDmesh K5 technology. It is designed for high-voltage switching applications requiring low gate charge and fast switching performance.

 

Key electrical specifications include a drain-to-source voltage (Vdss) of 800V, continuous drain current of 3A at Tc=25°C, and a maximum on-resistance of 2.6Ohm at Id=1.2A and Vgs=10V. The device features a maximum gate charge of 4nC at Vgs=10V and an input capacitance of 110pF at Vds=100V, enabling efficient high-frequency operation.

 

The MOSFET is rated for a maximum power dissipation of 38W at Tc=25°C and operates over a junction temperature range of -55°C to 150°C. It is supplied in an 8-PowerVDFN surface-mount package with a PowerFlat (5x6) VHV footprint, suitable for compact power supply designs.
