Input capacitance is 400 pF at 50 V drain-source, so the driver doesn't need to be a high-current type. The 45 W power dissipation limit at the case is the thermal ceiling — derate for ambient temperature above 25°C. ## DPAK footprint and temperature range The tab is the drain, so the PCB copper area acts as the heatsink — a 1-inch-square pad on a 2-oz copper board can dissipate roughly 1.5–2 W before the junction hits 100°C.","metaTitle":"STD7NM50N N-Channel MOSFET, 500 V, 5 A, DPAK","metaDescription":"STD7NM50N N-Channel MOSFET from STMicroelectronics MDmesh™ II series. 500 V drain-source, 5 A continuous drain, 780 mOhm Rds(on).

For a new design, look at current MDmesh™ series parts with similar voltage and current ratings, such as the STD7NM50N's MDmesh™ II family siblings, but verify pin compatibility and thermal performance. For an existing BOM, a parametric search for 500 V, 5 A, DPAK N-channel MOSFETs from other manufacturers may yield a drop-in alternative, but each candidate must be validated for gate drive voltage and switching losses."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STD7NM50N","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STD7NM50N when reusing this data.
