Selection guides, application notes and design checks for rectifiers, Schottky diodes, TVS protection, MOSFETs, SiC and IGBTs — written for engineers and sourcing teams.
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 modified date: … 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. (Last modified date: August 31, 2026) The Method in One Sentence: … Read more
The AWSS10H60 is a 10 A, 60 V Schottky barrier rectifier in an eSGC (TO-277) package from Good-Ark, positioned for high-current automotive lighting.

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. Why Solder Joints Fail in Lamp Modules The lamp module’s … 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.

The AWSS family covers the automotive lighting and ECU domain with four parts in one footprint: 5 A and 10 A, crossed with 60 V and 100 V, all in eSGC (TO-277). This guide maps the lineup, matches the load, and walks the sample and validation strategy. Four Parts, One Family: The AWSS Lineup Map … Read more
Compact drivers are moving away from the SMC package, and the PDFN56 AMBRP10H100 is a common landing point: smaller footprint, better thermal path, and the same 10 A/100 V class. This guide covers the footprint and thermal comparison, the electrical parity check, and the migration steps from PCB to validation. Why Designers Are Moving Away … Read more
The AMBRP10H100 is a 10 A, 100 V Schottky barrier rectifier in a PDFN56 package from Good-Ark, with 0.76 V typical forward drop at 10 A, a 180 A surge rating, and 3 °C/W junction-to-case resistance. It targets automotive lighting, ECU, and SMPS output stages where a low-profile, board-mounted rectifier carries real current. This article … Read more
