This page organizes our engineering articles by product family so you can learn how each device type works, how to compare parts, and how to select the right one for your design. It is a learning path, not a catalog: official product lists and datasheets are maintained on the Good-Ark website at en.goodark.com.
Power MOSFETs
MOSFETs dominate low- and mid-voltage switching. Start with polarity selection, then dive into RDS(on) trade-offs, logic-level drive, structure choices and super-junction designs. Packaging matters too: see TO-252 (DPAK) thermal design.
Silicon Carbide (SiC)
SiC brings high-voltage efficiency to solar, charging and server power. Read 650V SiC in PFC and server power, 1700V SiC for solar and rail, 1200V SiC selection, and junction-temperature reliability. For purchasing teams: what to verify before SiC design-in.
IGBTs
IGBTs remain the workhorse for high-power, medium-frequency switching. See 650V devices for induction heating, 1200V devices for motor drives, and the IGBT sourcing guide.
Rectifiers & Fast-Recovery Diodes
Rectification is the backbone of power conversion. Learn how to choose a power rectifier and how to compare datasheets, then explore axial, SMD, high-voltage and high-current families. For switching applications, see fast-recovery diodes, ultra-fast recovery selection, and package guides: TO-220, SMB, SMA, TO-247. Popular axial parts are covered in the 1N4004G, 1N4001G and 1N4002G articles.
Schottky Barrier Diodes
Schottky devices deliver low forward voltage and fast switching. Start with the practical selection guide, then explore dual common-anode, dual common-cathode, high-current, low-VF, SMD, automotive and trench variants.
TVS & ESD Protection
Protection devices keep designs alive. Compare the SMBJ, SMAJ and SMCJ families, the 1500W TVS and 600W TVS classes, plus low-clamping-voltage and the TVS family guide. For ESD: CAN bus, USB, low-capacitance, automotive, multi-line arrays and SOD-523.
Zener & Voltage Reference Diodes
For regulation and reference: voltage-regulator Zener basics, SMD Zener regulators and precision references.
Bridge Rectifiers
AC-to-DC conversion often starts with a bridge. See low-profile bridges, single-phase modules, three-phase modules, SMD packages and the standard bridge deep guide.
Small-Signal Devices & Transistors
Signal-level switching and conditioning: SOT-23 bipolar transistors, NPN, PNP, pre-biased, digital switching, small-signal Schottky, SOT-23 switching diodes, high-speed switching and SOD-123.
