Even experienced technicians make errors during an f4901 11a 24v schematic install. Avoid these:
At 11A, conduction loss = I² × Rds(on) = 121 × 0.012 = 1.45 W. With RθJA ~ 45°C/W (natural convection), temperature rise ≈ 65°C above ambient. For 50°C ambient, case temp = 115°C (acceptable for industrial grade). For higher ambient, forced air or reduce current to 9A. f4901 11a 24v schematic install
