Rectifiers

Convert AC to DC using diodes; used in power supplies.

Schottkys (Schottky Diodes)

Fast-switching diodes with low forward voltage drop. Ideal for power efficiency and high-speed applications.

Bridges (Bridge Rectifiers)

Use 4 diodes to convert AC to DC more efficiently; found in most AC-to-DC converters.

Zeners (Zener Diodes)

Used for voltage regulation; operate in reverse breakdown to clamp voltage at a specific level.

TVS (Transient Voltage Suppression Diodes)

Protect circuits from voltage spikes; clamp dangerous transient voltages to safe levels.

Thyristors

Four-layer semiconductors (like SCRs); used for high-power switching (e.g., motor drives, AC power control).

MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors)

Voltage-controlled devices; common in switching power supplies and motor control.

Gallium Nitride (GaN) Power FETs

Advanced, high-efficiency power transistors; used in fast, compact power systems (high-frequency switching).

JFETs (Junction Field-Effect Transistors)

Voltage-controlled with high input impedance; often used in analog circuits and amplifiers.

IGBTs (Insulated-Gate Bipolar Transistors)

Combine MOSFET input with BJT output; ideal for high-voltage, high-current switching (e.g., EV inverters, motor drives).

Transistors

General-purpose devices (BJTs, FETs); used for amplification, switching, signal modulation.

IC & Voltage Regulator

Integrated circuits that stabilize voltage levels; includes linear regulators (e.g., 7805) and switching regulators (e.g., buck/boost).
