James IFSM—peak forward surge current—is a single-pulse rating: the part survives one large current event at a defined pulse width and starting temperature, and every repeated event ages it. This guide explains what the number actually means, how it is tested, and how to check it against the real events your circuit produces. Last updated: October … Read more
Forward voltage (VF) is not a fixed datasheet number; it is a function of current, junction temperature, and device construction. Design with the maximum VF at the operating temperature, and the loss math—conduction loss is simply IF × VF—stops producing surprises. This guide covers the physics behind the number, how it moves with temperature, and … Read more
A transient voltage suppressor is selected by three voltages, in order: the stand-off voltage (VRWM) that the circuit must tolerate continuously, the breakdown voltage (VBR) where conduction starts, and the clamping voltage (VC) that the protected node will see during the surge. This guide explains the three, the waveform behind the power class, and the … Read more
A three-phase bridge rectifier uses six diodes to produce six output pulses per cycle, delivering smoother DC than a single-phase bridge and using the three-phase source efficiently. This guide covers the conduction sequence, the ratings that change with line voltage, the thermal reality, and how to size an SGBJ-class bridge for industrial input. Last updated: … Read more
In a bridge, two diodes conduct in series during every half-cycle, so the forward drop is doubled—and at a 5 V output, a 0.5 V saving per diode is 20% of the rail. A Schottky bridge delivers that saving for low-voltage AC inputs, within a voltage ceiling and a leakage budget. This guide covers where … Read more
A standard bridge is built for 50/60 Hz, and at higher input frequencies its recovery behavior turns into loss, ringing, and heat. A fast recovery bridge replaces the slow diodes with recovery-controlled ones, earning its keep in 400 Hz systems, high-frequency AC links, and telecom rectifiers. This guide covers where the family wins, how to … Read more
A bridge rectifier turns AC into pulsating DC with four diodes in one package, and the package is the point: matched die, consistent thermal behavior, and one assembly step instead of four. This guide explains the full-wave operation, the three bridge families, the ratings, and the package reality behind the catalog rows. Last updated: October … Read more
A general-purpose silicon rectifier diode does four jobs in a circuit—rectify, freewheel, clamp, and block reverse current—and it is the right part whenever the voltage fits, the frequency is low, and the loss budget accepts a higher forward drop. This guide covers the four roles, the datasheet read row by row, and the upgrade path … Read more
Selecting a Schottky rectifier means balancing four ratings—reverse voltage, average current, surge current, and junction temperature—against the leakage and forward-drop tradeoffs that change with every voltage class. Work through the ratings in a fixed order, verify the thermal budget at the hottest working condition, and the selection writes itself. This guide walks through that process … Read more
Key Takeaways QFN and DFN are the leadless workhorses of modern power and signal electronics: small, low-inductance, and thermally capable when the PCB cooperates. Before you finalize the BOM, compare the related options: TO-252 (DPAK) Power MOSFETs and Low RDS(on) Power MOSFETs. Verify your choice against official product data and application guidance: Good-Ark MOSFET product … Read more
Key Takeaways In a converter switching at 500 kHz or 1 MHz, the gate driver is not a peripheral—it is the timing engine. Before you finalize the BOM, compare the related options: High-Speed Gate Driver Design for GaN Half-Bridges and Isolated Gate Drivers for High-dv/dt SiC and IGBT Bridges. Verify your choice against official product … Read more
Blocking Diodes: When They Are Necessary A blocking diode allows current to flow from the module to the load but not backward. The classic case is off-grid: at night, a battery connected to the panel would discharge through the module’s series resistance and reverse-bias the cells. The blocking diode stops the reverse current and protects … Read more
