Tools & Software

ST’s low V F , 200 to 400 V ultrafast diodes were designed with a priority on V F to minimize conduction losses, while the diodes remain fast enough to belong to the ultrafast category of diodes. In this way, these low V F diodes perfectly fit applications where the switching frequency is counted in tens of kilohertz.
