If your design is still in the layout phase, consider qualifying a current-production alternative in the same TO-220 footprint to avoid a future last-time-buy scramble. The STP7NK30Z requires a 10 V gate drive to achieve the rated on-resistance. The gate threshold voltage (Vgs(th)) is a maximum of 4.5 V at 50 µA drain current, so a standard 12 V gate drive from a PWM controller or driver IC is sufficient. Total gate charge (Qg) is 13 nC at 10 V, which keeps the gate-drive power modest even at moderate switching frequencies — a 100 kHz switching rate draws about 1.3 mA average from the gate-drive supply. Input capacitance (Ciss) is 380 pF at 25 V drain-source, consistent with a device sized for a few amps. The ±30 V maximum gate-source rating gives ample headroom for driving with a 12 V rail, but a gate-source Zener clamp is still good practice if the gate-drive transformer or bootstrap circuit can overshoot. ## Thermal and mounting considerations The TO-220-3 through-hole package is a standard vertical-mount power package. The junction-to-case thermal path is the primary heat-removal route — the 50 W power dissipation rating assumes a case temperature held at 25°C, which in practice requires a substantial heatsink and thermal interface material. For a 5 A load at 900 mOhm, the junction temperature rise above case is about 5.6 W × RθJC; with a typical RθJC around 2.5°C/W (not in the ledger but implied by the package class), the die runs about 14°C above the case temperature at full rated current. Mount the device with a screw and thermal compound to a heatsink sized for your worst-case ambient.","metaTitle":"STP7NK30Z N-Channel MOSFET, 300 V, 5 A, TO-220-3","metaDescription":"STP7NK30Z SuperMESH N-Channel MOSFET, 300 Vdss, 5 A continuous drain, 900 mOhm Rds(on) at 10 V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"SuperMESH™","Package":"Tube","FET Type":"N-Channel","Vgs (Max)":"±30V","Technology":"MOSFET (Metal Oxide)","FET Feature":"-","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Vgs(th) (Max) @ Id":"4.5V @ 50µA","Base Product Number":"STP7N","Operating Temperature":"-55°C ~ 150°C (TJ)","Rds On (Max) @ Id, Vgs":"900mOhm @ 2.5A, 10V","Power Dissipation (Max)":"50W (Tc)","Supplier Device Package":"TO-220","Gate Charge (Qg) (Max) @ Vgs":"13 nC @ 10 V","Drain to Source Voltage (Vdss)":"300 V","Input Capacitance (Ciss) (Max) @ Vds":"380 pF @ 25 V","Drive Voltage (Max Rds On, Min Rds On)":"10V","Current - Continuous Drain (Id) @ 25°C":"5A (Tc)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5506dc19a081b2fcb10efe53af5a2c3c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STP7NK30Z/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STP7NK30Z","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STP7NK30Z when reusing this data.
