Diodes are two-terminal active semiconductor components designed to allow electrical current to flow predominantly in one direction while blocking reverse current, performing fundamental rectification, signal demodulation, voltage clamping, and voltage reference functions in power supplies, signal chains, and protection circuits.
This massive product category covers standard rectifier diodes, fast and ultrafast recovery rectifiers, Schottky barrier diodes for high-efficiency switching, Zener diodes for voltage regulation, switching diodes, and Transient Voltage Suppressor (TVS) diodes for ESD protection. Critical selection metrics include maximum repetitive reverse voltage (VRRM), average forward current (IF), forward voltage drop (VF), reverse recovery time (trr), and package footprint (axial vs. surface-mount SMD packages like SOD-123, SMA, and SMB).
Octatronics catalogs a massive selection of diodes from industry leaders including Vishay Intertechnology, Nexperia, onsemi, Diodes Incorporated, and ROHM. Filter by diode type, package, and electrical specifications, and easily submit bulk RFQs online.
