MOSFETs
MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) are voltage-controlled switches that dominate modern power conversion, motor drive, and signal switching applications. Selection criteria include drain-source voltage (VDS), continuous drain current (ID), on-resistance (RDS(on)), gate charge (Qg), and thermal resistance. Octatronics indexes 8,900+ MOSFETs from Infineon, onsemi, Vishay Siliconix, Nexperia, Toshiba, and ROHM.

How to Choose MOSFETs
A practical selection framework for MOSFETs covering specifications, packaging, lifecycle, and sourcing on Octatronics.
Define electrical and environmental requirements
Start with the required function and operating conditions for MOSFETs, then lock in critical parameters such as breakover voltage, on-state current, gate trigger current, holding current, and dv/dt capability. Match these against datasheet limits, not catalog summaries alone.
Validate package and land pattern compatibility
Confirm the MOSFETs package matches your PCB footprint, pick-and-place constraints, and moisture sensitivity handling. Verify reel/tape or tube packaging for production.
Check lifecycle, compliance, and alternates
Review lifecycle status (Active, NRND, EOL), RoHS, and approved alternate sources for MOSFETs before committing to high-volume builds. Use Octatronics cross-reference data when a drop-in replacement is needed.
Compare manufacturers and request pricing
Filter MOSFETs by manufacturers such as onsemi and ROHM, compare key specs side by side, then submit an RFQ with quantity, target delivery, and traceability requirements.
