Design Notes
The STL35N75LF3 in PowerFLAT 5x6 package requires adequate PCB copper area for heat dissipation. Use multiple thermal vias under the exposed pad to conduct heat to the ground plane. For continuous operation at high currents, ensure the junction temperature stays below 150Β°C. Calculate power dissipation using P = I^2 * RDS(on) and verify thermal resistance.
Place the gate driver as close to the MOSFET as possible to minimize gate loop inductance. Use a gate resistor (typically 10Ξ©) to control switching speed and reduce EMI. Keep the source connection short and direct to the driver ground to avoid parasitic inductance. For high-current paths, use wide copper traces and multiple vias to reduce resistance.
Do not exceed the maximum VDS of 35V, as this can cause avalanche breakdown. Ensure the gate-source voltage is within the absolute maximum rating to prevent gate oxide damage. When paralleling multiple MOSFETs, use separate gate resistors to avoid oscillation. Always consider the effect of temperature on RDS(on), which increases with temperature, leading to higher conduction losses.
