The maximum junction temperature (Tj) that the STB80NF03L-04-1 can withstand is 150°C, as specified in the datasheet.
Yes, the STB80NF03L-04-1 is AEC-Q101 qualified, which means it is suitable for use in automotive applications.
STMicroelectronics provides a recommended PCB layout in the application note AN4305, which includes guidelines for thermal pad design, copper thickness, and via placement to minimize thermal resistance.
You can calculate the power dissipation of the STB80NF03L-04-1 using the formula Pd = (Vds x Ids) + (Vgs x Igs), where Vds is the drain-source voltage, Ids is the drain-source current, Vgs is the gate-source voltage, and Igs is the gate-source current. You can find the values for these parameters in the datasheet or by measuring them in your application.
Yes, the STB80NF03L-04-1 is compatible with lead-free soldering processes, as it is RoHS compliant and meets the requirements of the European Union's Directive 2011/65/EU.
