This puts it in the medium-voltage, moderate-current class — suitable for switching loads in offline power supplies, DC-DC converters, and motor pre-drive stages where the bus rail sits at 48 V to 150 V and the peak current stays under the 17 A ceiling. ## Conduction loss and gate drive budget Maximum on-resistance is 165 mOhm at 8.5 A drain current with a 10 V gate drive. At 17 A the Rds(on) will be higher due to self-heating — the 90 W power dissipation limit at the case is the thermal budget that governs the real-world current derating. The 29.5 nC total gate charge at 10 V means the gate driver must supply roughly 2.95 mA per 100 kHz of switching frequency just to charge the gate capacitance; the 1000 pF input capacitance at 25 V drain-source adds to the switching loss calculation. ## DPAK thermal and mounting Housed in the DPAK (TO-252) surface-mount package with an exposed drain tab. The tab must be soldered to a copper pad on the PCB — the thermal resistance to ambient depends on the board's copper area and layer count. The -55°C to 150°C junction temperature range covers industrial ambient and under-hood automotive environments, but the 150°C upper limit means the thermal design must keep the junction below that at full load.","metaTitle":"STD17NF25 STMicroelectronics N-Ch MOSFET, 250 V, 17 A, DPAK","metaDescription":"STD17NF25 N-channel 250 V 17 A MOSFET in DPAK. 165 mOhm Rds(on), 29.5 nC gate charge.

At a 100 kHz switching frequency, the average gate-drive current is about 2.95 mA — well within the capability of most dedicated MOSFET drivers, but a microcontroller GPIO driving directly may struggle to source that current at the required rise time."},{"question":"Will STD17NF25 drop into a board designed for STD17NF03LT4?","answer":"No. The STD17NF03LT4 is a 30 V device with a different Rds(on) and gate charge profile. The STD17NF25 is rated for 250 V drain-source — the pinout and package (DPAK) are the same, but the 250 V rating means the board's clearance and creepage must support the higher voltage. A direct swap without verifying the circuit's voltage stress is not recommended."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STD17NF25","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STD17NF25 when reusing this data.
