650V SiC MOSFETs for PFC and Server Power: When SiC Moves Down to 650 V

650V SiC MOSFETs for PFC and Server Power: When SiC Moves Down to 650 V

Key Takeaways Silicon carbide built its reputation at 1200 V, where silicon has no clean answer. Before you finalize the BOM, compare the related options: 650V SiC MOSFETs for PFC and Server Power and 1700V SiC MOSFETs for 1500V Solar and Rail Power. Verify your choice against official product data and application guidance: Good-Ark SiC … Read more

SiC Power Device Design Guide: Voltage, Topology, and Reliability

This guide is the entry point to the Good-Ark silicon carbide library. It maps the SiC decisions—which voltage class, which device (MOSFET or diode), which topology, and how hot the design can run—and points to the dedicated articles that carry the detail. Use it to position the design before the datasheet comparison. The SiC Decision … Read more

How to Select a PV Bypass Diode: VF, Leakage, Surge, and Thermal Limits

The bypass rectifier is the smallest component in a solar module and one of the most thermally stressed: it carries the full string current in a sealed junction box, at high ambient, for hours under shading. Its selection is a rating exercise—forward drop, leakage at temperature, surge, and the thermal path—and getting any of them … Read more

PV Bypass Diode Modules vs Discrete Diodes: Assembly, Thermal, and Reliability

A solar module’s bypass protection can be built from discrete diodes or from a bypass diode module—an integrated assembly that packages several diodes, the lead frame, and often the connectors into one unit. The two approaches reach the same electrical function through different assembly and thermal paths, and the choice affects production yield, field reliability, … Read more

TO-247 vs TO-220 vs D2PAK IGBTs: Thermal Mounting and Module Crossover

Not every IGBT design needs a power module. Below a few tens of kilowatts, discrete IGBTs in TO-247, TO-220, and TO-263 packages carry the load with lower cost, simpler sourcing, and a flexible layout—provided the package’s thermal, mounting, and insulation realities are respected. This article covers the discrete side of IGBT selection: how the packages … Read more

1200V SiC Diodes for EV Charging and Industrial PFC: Selection Criteria

The 1200 V silicon carbide diode is the quiet workhorse of high-voltage power stages: it blocks the DC bus, carries the boost current, and freewheels the load—without the reverse-recovery penalty that forces silicon designs to compromise. This article is about the device-selection side of that story: which ratings matter at 1200 V, which application roles … Read more

PV Protection Architecture: Bypass Diodes, Blocking Diodes, String Fuses, and Surge Protection

This guide is the entry point to the Good-Ark photovoltaic protection library. It maps the protection layers of a PV system—from the module substring to the inverter input—and routes each threat to the right device and the right article. Use it to position the protection architecture before selecting components. The Protection Layers PV protection is … Read more

Gate Drive Design Guide: Sizing, Timing, and Protection

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 articles for the device … Read more

Power Package Thermal Design: From Rth(j-a) to Junction Temperature

This guide is the shared reference for the thermal method used across the Good-Ark package and device articles. It explains the thermal chain, the board design levers, and the measurement discipline, so the package-specific articles can focus on their own differences instead of repeating the fundamentals. If you are new to power thermal design, read … Read more

Power Discrete Package Testing: What to Verify Before Mass Production

The gap between a power device that works on the bench and one that survives years in the field is filled by testing—at the datasheet level, the thermal level, the reliability level, and the assembly level. For engineers and buyers qualifying power discretes, understanding what is tested, how, and with what criteria separates a trustworthy … Read more

Isolated DC-DC Power Modules for Gate Drive and Industrial Control: Selection

An isolated DC-DC converter can be built from a transformer, a controller, and a handful of discrete parts—or bought as a module that packages all of it into one component. For gate-drive supplies, industrial control boards, and sensor power, the module is often the engineering-correct choice: it moves the isolation design, the magnetics, and the … Read more
