Updated: October 27, 2026 A practical power MOSFET selection guide starts with voltage and polarity, then loss (conduction + switching), gate-drive limits, and package thermal reality on your PCB. Use this map with N- vs P-channel, SMPS MOSFET choice, and IGBT basics when silicon FETs stop fitting the operating point. The Selection Map Power MOSFET … Read more
Updated: November 9, 2026 This guide is the shared reference for gate-drive design across the Good-Ark library. It covers the two questions every drive design answers—how much current, and how much dead time—plus the protection set, and it routes the device-specific detail to the dedicated articles. Read this page for the method; read the linked … Read more
Updated: October 27, 2026 N-channel vs P-channel is a polarity and drive decision: most high-efficiency load switches and power stages favor N-channel with appropriate high-side drive, while P-channel simplifies high-side switches at the cost of RDS(on) and size. Pair with power MOSFET selection guide and MOSFET for SMPS. Need Often better Why Low-side switch N-channel … Read more
Updated: November 11, 2026 Every MOSFET datasheet leads with RDS(on), and it is tempting to sort a supplier table by that number and take the smallest value. But on-resistance is bought with silicon area, and silicon area is bought with gate charge, switching loss, and cost. This article explains the economics behind low RDS(on), works … Read more
The TO-252, also called DPAK, is the workhorse surface-mount power package: small enough for high-volume assembly, rugged enough for automotive and industrial boards, and thermally capable when the PCB is designed properly. Its performance, however, is decided more by the copper around it than by the package itself. This article explains how a TO-252 MOSFET’s … Read more

Key Takeaways Super junction MOSFETs use charge-balanced pillars to break the classic voltage-versus-RDS(on) trade-off, which is why they dominate high-voltage PFC, flyback and LLC stages. Compare datasheets by application conditions — RDS(on) at the real junction temperature, not the 25 °C headline number; our low RDS(on) guide explains where the money actually goes. Pair the … Read more
Key Takeaways Two letters on a datasheet—”trench” or “planar”—tell you more about a power MOSFET than most of its front-page numbers. Before you finalize the BOM, compare the related options: Trench vs Planar MOSFETs and TO-252 (DPAK) Power MOSFETs. Verify your choice against official product data and application guidance: Good-Ark MOSFET product families and Good-Ark … Read more
