Key Takeaways Bypass diodes carry the full module current during partial shading; thermal design inside a plastic junction box is what decides survival, not just the diode rating. Match VF, leakage and surge capability to the module current and temperature — see the photovoltaic diode engineering guide and our module and string protection article. For … Read more
Key Takeaways The isolated gate driver has two jobs: amplify the controller signal into a fast, strong gate pulse and isolate the low-voltage side from a floating power rail. For SiC and IGBT bridges, evaluate dv/dt immunity, propagation delay, dead-time control and CMTI — our GaN half-bridge drive guide covers the timing side. Match driver … Read more

General purpose rectifier diodes are the practical choice for 50/60 Hz transformer secondaries, low-frequency bridge rectifiers, relay flyback paths, and simple reverse-polarity protection. This guide answers a narrow design question: when is a 1N400x-, 1N540x-, or equivalent standard silicon rectifier appropriate, and how should it be sized in a capacitor-input supply? The important stress is … Read more
The decisive question is not whether a standard rectifier can conduct the required current, but whether it can stop conducting before the next switching transition. Standard-recovery silicon diodes are economical and dependable at line frequency, yet stored minority-carrier charge can impose reverse-recovery current on a MOSFET or IGBT in faster converters. That current raises turn-on … Read more
A silicon PN rectifier trades stored charge for robust voltage blocking, mature manufacturing, and attractive cost. This page explains that trade at device-physics level: how the depletion region blocks reverse voltage, how drift-region thickness and doping set resistance and breakdown capability, and why injected minority carriers reduce conduction loss but later create reverse-recovery charge. Those … Read more
In high-current rectification, RMS heating, surge energy, and the thermal interface often matter more than the headline current rating. This guide treats the diode as part of a power assembly: semiconductor, package, busbar or PCB, thermal-interface material, heatsink, mounting hardware, and the commutating MOSFET or IGBT. It connects IF(AV), IF(RMS), IFSM, I²t, conduction loss, recovery … Read more
At high voltage, the diode rating is only one part of the insulation system. PCB creepage, air clearance, contamination, humidity, altitude, field concentration, potting materials, and measurement technique can become the actual failure limit. This guide focuses on preventing puncture, surface tracking, corona, and partial-discharge damage in high-voltage rectifiers and series stacks. It explains why … Read more
For an SMD rectifier, the PCB is not merely a mounting surface—it is a major part of the heatsink and the assembly process. This guide starts with SMA, SMB, SMC, and related package choices, then connects land pattern, copper area, layer stack, thermal vias, solder paste, voiding, and nearby heat sources to junction temperature and … Read more
