A faster-than-average current rectifier is a fast diode. Fast and ultrafast rectifiers are described in comparison to conventional rectifiers, which are made for low-frequency uses such rectifying sinusoidal current from an AC mains supply.
Put the multimeter between the anode and the cathode (+ on 1 or 3, – on 2) to test them; they ought to produce a forward voltage of about 0.7V.
The Global Ultrafast Rectifier Diode market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
To achieve the optimal performance for every application, ST offers ultrafast diodes with trade-offs between forward voltage (VF) and reverse recovery time (tRR).
Due to their distinctive reverse recovery charge (QRR) and softness trade-offs, each of the specific series of these 600V ultrafast diodes targets a relatively narrow range of applications based on converter/PFC frequency and noise imperatives. Some of them can also be utilized as ideal secondary rectification diodes in circuits at the bottom of the converter line-up.
ST’s R series of low QRR, 600 V ultrafast diodes are designed for PFC (power factor corrector) applications that operate in continuous mode and under challenging switching situations. They are optimized for rapid recovery circuits. The current spectrum of this series, which has a low reverse recovery charge (QRR), ranges from 4 to 30 A.
