Selection guides, application notes and design checks for rectifiers, Schottky diodes, TVS protection, MOSFETs, SiC and IGBTs — written for engineers and sourcing teams.
Incoming inspection is where the datasheet becomes the acceptance line: the visual and mechanical checks catch the obvious, the electrical spot checks verify the ratings, and the traceability ties every lot to its evidence. This guide covers the practice, the checks, and the sampling. Why Incoming Inspection Pays Incoming inspection is the cheapest quality control … Read more
The TO-277 (eSGC) package is the automotive board-level 5 A workhorse, and its exposed pad is the thermal contract: the pad, the vias, the copper, and the stencil decide whether the package performs to its data. This guide covers the construction, the footprint, the thermal comparison, and the assembly. TO-277 Construction and Why It Exists … Read more
In a PDFN leadless package, the exposed bottom pad is the electrical and thermal exit: it carries current, conducts heat into the board, and decides whether the part performs to its datasheet. This guide covers pad design, thermal vias, stencil and reflow, and the inspection that verifies the joint—using the PDFN56 packages of the AMBRP … Read more
An SMD package absorbs moisture from the air, and at reflow temperatures that moisture turns to steam inside the body—cracking the package, lifting the die, or delaminating the lead frame. The moisture sensitivity level (MSL) rating tells you how long the part can sit out before that risk appears. This guide covers the mechanism, the … Read more
Rectifier layout is the engineering of loops: the switching loop, the ground return, and the thermal path decide the noise and the temperature, and the layout review is the design’s final gate. This guide covers the critical-loop concept, the input and output sides, and the thermal separation. The Critical Loop Concept Every switching rectifier circuit … Read more
Motor-drive input bridges fail in recognizable patterns—repeated surges, phase loss, and overvoltage—and the evidence chain reads the pattern before the fix. This guide covers the stress profile, the patterns, the failure analysis, and the corrections. The Drive Input Stage’s Stress Profile The motor drive’s input bridge lives in the harsh-grid reality: line dips and surges, … Read more
PV bypass diode failures appear as string underperformance or a damaged junction box, and the evidence chain runs from the shading pattern to the junction-box temperature. This guide covers the failure mechanisms, the hot-spot damage patterns, the thermal evidence, and the module-versus-device attribution. Why Bypass Diodes Fail in the Field The bypass diode conducts the … Read more
Noise on a rectifier output is three different problems wearing one name: low-frequency ripple from the filter, high-frequency switching noise from the converter, and ringing from the layout. Classifying the symptom first decides the fix. This guide walks the classification, the probing, the rectifier-specific sources, and the cures. Symptom Classification: Ripple vs Switching Noise vs … Read more
The on-board charger is moving in three directions at once: bidirectional power flow, higher bus voltages, and higher power density. Each trend changes the rectifier story, and this guide traces the three causal chains and their device implications. The Bidirectional Trend: V2X Changes the Power Flow Vehicle-to-everything (V2X) capability turns the OBC from a one-way … Read more
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. The Lighting Evolution … 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. Module, String, and Storage Architectures The architecture decides where the diodes sit. A … 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 modified date: August 31, 2026) TVS Failure Diagnosis — … Read more
