The STP75N3LLH6 is listed as obsolete. That means STMicroelectronics no longer manufactures it, and no last-time-buy window is open. For a production BOM, this part is a single-source risk unless you already hold inventory. ## Key ratings and the decisions they drive At 75 A, the dissipation in the channel alone is I²R = 75² × 0.0059 ≈ 33 W, which must be sunk by the heatsink — the 60 W package limit at the case gives some headroom, but thermal design is critical. The 23.8 nC gate charge at 4.5 V tells you the driver doesn't need a 10 V rail; a 5 V logic-level output can turn it on fully, though the Rds(on) will be higher at 4.5 V than at 10 V. Input capacitance of 2030 pF at 25 V Vds is moderate — a typical gate driver with 1 A peak current can switch it in tens of nanoseconds, but the PCB layout must keep the gate loop tight to avoid ringing.","metaTitle":"STP75N3LLH6 N-Channel MOSFET, 30V 75A, TO-220-3","metaDescription":"STP75N3LLH6 N-Channel MOSFET from STMicroelectronics DeepGATE/STripFET VI series. 30V Vdss, 75A Id, 5.9mOhm Rds(on) at 10V.
