Dual N-channel in a 5x6 PowerFlat — what the package tells you
The STL8DN6LF3 is a dual N-channel MOSFET from STMicroelectronics' STripFET™ III series, housed in an 8-lead PowerVDFN with a PowerFlat (5x6) footprint. Without that pad connection, the junction temperature rises well above the 175 °C absolute maximum under sustained load.
