Tips: Difference between fast recovery rectifier diode and standard rectifier diode

Fast recovery rectifier diodes and standard rectifier diodes differ primarily in their recovery time and performance characteristics.

Recovery Time: Fast recovery diodes have shorter reverse recovery times, which allows them to switch more quickly between conducting and blocking states. This makes them suitable for high-frequency applications.
Switching Efficiency: Fast recovery diodes minimize power losses during switching, improving overall efficiency in power conversion circuits.
Applications: Fast recovery diodes are often used in applications like switch- mode power supplies and inverters, while standard rectifier diodes are commonly found in low-frequency circuits, such as simple rectification tasks.
Construction: Fast recovery diodes typically have designs optimized for rapid switching, whereas standard diodes may prioritize robustness over speed.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
