James The TVS’s placement decides whether the datasheet’s clamp is the circuit’s clamp: close to the connector, short to ground, and a small loop are the rules, and the parasitic inductance is the enemy. This guide covers the rules, the overshoot, the PCB checklist, and the pulse verification. Last updated: October 11, 2026 Why Placement Matters … Read more
Paralleling two rectifier diodes raises the current capability only if the branch currents actually split as intended, and the split is decided by the VF match at temperature, the layout symmetry, and the measurement. This guide covers the motivation, the sharing physics, the layout rules, the derating, and the verification that make a parallel pair … Read more
Ringing on a rectifier’s switching node is the layout’s parasitics talking, and the snubber is the damping answer: an RC snubber is the first tool, sized by hand from the measured waveform, and an RCD snubber takes over at higher power. This guide covers the source, the calculations, the component selection, and the bench verification. … Read more
SMB (DO-214AA) and SOD-123 packages carry TVS and small rectifier functions, and their small mass makes them more sensitive to the reflow process than the power packages beside them. This guide covers the process sensitivity, the pads, the tombstone defect, and the inspection that keep a small package reliable on a production board. Last updated: … Read more
Lead-free soldering raises the reflow temperature and puts the moisture-sensitivity discipline on a tighter clock, and power rectifiers are among the most exposed packages. This guide covers what lead-free changes, the profile parameters, the peak-versus-package limit, and the process qualification. Last updated: October 11, 2026 What Lead-Free Changes for Power Devices Lead-free solder alloys melt … Read more
Choosing a TVS from a catalog means navigating power classes, voltage families and packages before the datasheet is even opened. Good-Ark’s TVS portfolio spans axial and surface-mount series from the small-signal protection end to the high-energy DO-201 and SMC classes, and the search starts with the rail voltage and the surge energy, not with a … Read more
A part search for “GS” returns silicon MOSFETs and SiC Schottky diodes with the same prefix, and the engineer who does not read the full part number can design a three-terminal transistor where a two-terminal diode belongs. Good-Ark’s silicon-carbide portfolio is two families with one naming trap: GS-series SiC Schottky diodes for rectification and freewheeling, … Read more
An automotive program does not buy a diode; it buys a part with qualification evidence, a mission-profile fit and a traceable supply chain. Good-Ark’s automotive discrete portfolio spans rectifiers, Schottky diodes, TVS and protection parts, MOSFETs and wide-bandgap devices organized by function, so a design team can start from the electrical role and find the … Read more
Replacing a discontinued diode is a specification exercise rather than a search exercise, and the difference matters because the obvious approach — finding something with a similar number — produces false confidence. The method below takes about twenty minutes per part and produces a substitution you can defend. When replacement is the right move Replacement … Read more
The difference between a useful datasheet and a dangerous one is provenance. A file with the right part number but the wrong revision, or no issuing manufacturer at all, will look correct and lead to a wrong design decision. Establishing where a document came from takes about two minutes and is worth doing every time. … Read more
The 24 V rail in an industrial cabinet and the 24 V rail in a truck look alike on a label and behave very differently under transients. The industrial rail carries switching spikes from contactors and motor drives; the truck rail adds load dump, cranking dips and the harsh pulses of commercial vehicles defined by … Read more

An engineer searching for “Schottky rectifier” faces a catalog problem, not a physics problem: the same technology appears in SOD-123 packages for signal clamping and in TO-220 dual-die parts for 20 A outputs, and the datasheet that fits one application is useless for the other. Good-Ark organizes its Schottky products by current class and function … Read more
