Gate charge is 54 nC at 10 V, and input capacitance measures 2200 pF at 25 V drain-source — numbers that matter for estimating switching losses and driver sizing in a 12 V or 24 V automotive or industrial power stage. For a BOM that already uses this part, the procurement path is the independent distribution channel — surplus, new-old-stock, or broker-sourced inventory. Any buy should include a visual inspection and parametric verification, especially on date codes more than a few years old. That is the drive voltage you need to hit the lowest Rds(on) — the part is not characterised at 4.5 V or 5 V logic levels, so a 10 V gate drive rail (or a gate driver that can deliver it) is assumed. The 54 nC total gate charge at 10 V gives a rough switching-energy figure: at moderate frequencies (20–50 kHz) the gate-drive loss is manageable; above 100 kHz the 2200 pF input capacitance starts to eat into efficiency, and a lower-Qg part might be a better fit. For a 40 A continuous rating, the 110 W maximum power dissipation at the case (Tc) means a decent heatsink is non-negotiable — the TO-220 tab needs a thermal interface to anything above a few amps.","metaTitle":"STP95N04 N-Channel MOSFET, 40V 80A TO-220, Obsolete","metaDescription":"STP95N04 STripFET N-channel MOSFET: 40V Vdss, 80A Id, 6.5mOhm Rds(on) at 10V.

For a new design, look for a current-production N-channel MOSFET in TO-220 with 40 V Vdss, 80 A Id, and ≤6.5 mΩ Rds(on) at 10 V. For a drop-in on an existing board, verify pinout and footprint against any candidate — the TO-220 pinout is standard, but gate threshold and drive voltage must match your circuit."},{"question":"Can the STP95N04 handle 40 A continuous?","answer":"Yes, the continuous drain current is rated at 80 A at 25 °C case temperature. At 40 A you are operating at half the rated current, well within the safe operating area — provided the case temperature is kept under control with adequate heatsinking. The 110 W maximum dissipation at the case is the thermal limit to watch."},{"question":"What is the Rds(on) of STP95N04?","answer":"The maximum Rds(on) is 6.5 mΩ at 40 A drain current with 10 V gate-source voltage. That is the spec you design to for conduction losses."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STP95N04","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STP95N04 when reusing this data.
