Frequently Asked Questions
How much conduction loss does DMN6040SFDE-7 generate at 3 A drain current in a 12 V load switch?
At 3 A with RDS(on) maximum of 38 mΩ, conduction power loss is P = I² × RDS(on) = (3)² × 0.038 = 342 mW. The U-DFN2020-6 package has a junction-to-ambient thermal resistance of approximately 60°C/W, causing a junction temperature rise of 342 mW × 60°C/W ≈ 20°C above ambient, so at 25°C ambient the junction reaches approximately 45°C — well within the 150°C maximum junction temperature rating.
Can DMN6040SFDE-7 withstand the inductive kick when switching a 12 V relay coil with 50 mH inductance?
Yes. The avalanche energy rating of the DMN6040SFDE-7 is 10 mJ. A 50 mH relay coil carrying 300 mA at switch-off stores E = ½ × L × I² = ½ × 0.05 × (0.3)² = 2.25 mJ, safely below the 10 mJ Eas limit. The built-in body diode also provides a freewheeling path for inductive flyback, and the 60 V drain-source breakdown voltage clamps the spike well above a 12 V supply.
What gate drive voltage does DMN6040SFDE-7 require for full enhancement in a 3.3 V logic-controlled circuit?
The DMN6040SFDE-7 is a standard-threshold MOSFET. Its VGS(th) is typically 1.2 V to 2.0 V, and at VGS = 4.5 V the RDS(on) is characterized at 38 mΩ maximum. At 3.3 V gate drive, the device turns on but RDS(on) rises above the 38 mΩ spec by approximately 20–30%. For guaranteed fully-enhanced switching at 3.3 V logic levels, a logic-level MOSFET with VGS(th) below 1.5 V or a gate driver boosting to 5 V is recommended.
