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

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
