Diodes

Diodes steer and clamp current to perform tasks such as rectification, signal routing, voltage referencing, and transient protection. Typical uses include power supplies, sensor interfaces, logic-level steering, indicator LEDs, and voltage reference or clamp circuits.

Choices vary by forward voltage, reverse breakdown, power dissipation, leakage, and switching speed. Low‑drop Schottky parts suit efficient power paths, Zener types create simple reference clamps, small‑signal and switching diodes handle logic and high‑speed switching, and rectifiers manage higher currents. Packaging and polarity options affect ease of integration onto PCBs or breadboards, while thermal and leakage characteristics determine reliability in different operating conditions.
