Automotive lighting moved from halogen to LED and now to matrix and adaptive systems, and the Good-Ark device families are part of the power-stage roadmap, and each step changed the power stage: more current, faster dimming, tighter protection, and a hotter lamp module. This guide traces the evolution and its device implications. Last updated: October … Read more

PV and energy storage systems are changing the electrical environment for power semiconductors: higher-power modules, 1500 Vdc architectures, SiC penetration in inverters, and bidirectional storage stages each shift what a diode must carry. This guide maps the trends and their component-selection implications. Last updated: October 16, 2026 Module, String, and Storage Architectures The architecture decides … Read more

A failed TVS is usually the protection telling you something: the rating was wrong for the waveform, the placement let the inductance win, or the pulse count exceeded the part’s capability. This guide covers the failure modes, the three classic mistakes, and the redesign checklist. Last updated: October 11, 2026 TVS Failure Diagnosis — Three … Read more

Surge damage leaves evidence before it leaves a part: a melted die, a cracked package, or a slow leakage drift. Reading the signature and tracing it to the event — inrush, lightning coupling, or load dump — is what turns a failed part into a protection upgrade. This guide covers the signatures, the tracing, and … Read more

A second source for a power semiconductor is an engineering decision, not a purchasing shortcut: the alternative must be qualified electrically, thermally, and mechanically before it earns a place on the BOM. This guide covers the qualification, the cross-reference, the lifecycle management, and the direct-manufacturer relationship that keep a supply strategy honest. Last updated: October … Read more

Ten amps continuous in a sealed automotive housing is a thermal case study: the forward-drop loss at temperature, the junction calculation, and the copper-and-housing countermeasures. This guide walks the worked case from loss to verification, with the parameters to confirm from the official datasheet.

AWSS10H60 appears in the Good-Ark new-release table as a 10 A, 60 V Schottky rectifier in eSGC (TO-277). The main design question is how the installed board handles a higher-current conduction path. The 10 A catalog label must be tied to a waveform, a mounting condition and a thermal limit. Last updated: October 16, 2026 … Read more

In an automotive lamp module, the solder joint under the TO-277 exposed pad is the weakest connection: thermal cycling and vibration fatigue it long before the die fails. This guide covers the mechanism, the footprint and process rules, the qualification thinking, and the design checklist. Last updated: October 16, 2026 Why Solder Joints Fail in … Read more

Data center power is moving toward higher PSU efficiency levels, 48V rack buses, and higher power per server, and the AC-DC input stage carries the consequences in voltage, current, and thermal duty. This report covers the efficiency roadmap, the 48V architecture, the input-stage implications, and the cooling context, with the sources noted at the end. … Read more

Energy storage systems are converging on DC-coupled architectures, battery racks in the 800–1500 Vdc range, and bidirectional power conversion, and each choice defines what the power semiconductors must carry. This report covers the architecture, the rack voltage, the PCS topologies, and the protection and thermal duty, with the sources noted at the end. Last updated: … Read more

The PV module industry has moved from full-cell, 60-cell panels toward half-cut cells and higher power classes, and the shift changes what the bypass stage and the junction box must carry. This report covers the cell-architecture trend, the power-class progression, the string-current consequences, and the qualification context, with sources noted at the end. Last updated: … Read more

AWSS5H100 appears in the Good-Ark new-release table as a 5 A, 100 V Schottky rectifier in eSGC (TO-277). The selection question is whether the higher reverse-voltage class is needed while the current requirement remains in the 5 A class. Increasing the voltage label alone does not settle the choice.
