Diodes are electronic components that conduct electric current in only one direction, functioning as a one-way valve. Diodes are manufactured using semiconductor materials such as silicon, germanium or selenium and are used as voltage regulators, signal rectifiers, oscillators and signal modulators / demodulators.
Electromechanical relays are devices that complete or interrupt a circuit by physically moving electrical contacts into contact with each other.
General-purpose diodes are electric components that conduct electric current in only one direction, functioning similarly to a one-way valve.
Insulated gate bipolar transistors (IGBT) are bipolar transistors with an insulated gate. They combine the advantages of the bipolar transistor (high voltage and current) with the advantages of the MOSFET (low power consumption and high switching).
Metal-oxide semiconductor field-effect transistors (MOSFETs) are electronic devices with a built-in capacitor as the input and a conducting channel as the output. An electrode called a gate controls the width of the channel and determines how well the MOSFET conducts.
Network and communication chips are semiconductor integrated circuits (IC) used in telecommunication devices and systems.
PIN diodes are three-layer semiconductor diodes consisting of an intrinsic layer separating heavily doped P and N layers. The charge stored in the intrinsic layer in conjunction with other diode parameters determines the resistance of the diode at RF and microwave frequencies.
Rectifier diodes are designed for use in rectification circuits. Rectifiers are used to convert AC to DC.
RF transistors are designed to handle high-power radio frequency (RF) signals in devices such as stereo amplifiers, radio transmitters, and television monitors.
Bipolar RF transistors consist of an N-type or P-type layer sandwiched between two layers of the opposite type. They are designed to handle high-power radio frequency (RF) signals in devices such as stereo amplifiers, radio transmitters, and television monitors.
Schottky diodes in their simplest form consist of a metal layer that contacts a semiconductor element. The metal / semiconductor junctions exhibit rectifying behavior (i.e., the current passes through the structure more readily with one polarity than the other).
Silicon controlled rectifiers (SCR) are four-layer (PNPN) thyristors with three terminals: an input control terminal (gate), an output terminal (anode), and a terminal common to both the input and output (cathode). SCRs are used mainly with high voltages and currents, often to control alternating current (AC) where the change of sign causes the device to switch off automatically.
Solid state relays (SSR) or semiconductor relays are semiconductor devices that can be used in place of mechanical relays to switch electricity to a load in many applications.
Specialty diodes are specialty or proprietary products and accessories related to diodes.
Specialty relays and accessories are specialty or proprietary products and accessories related to relays.
Specialty transistors are specialty or proprietary products and accessories related to transistors.
Thyristors are a class of four-layer (PNPN) semiconductor devices that act as switches, rectifiers, or voltage regulators.
Transistors are electronic devices made of semiconductor material that amplify a signal or open or close a circuit.
Triacs are three-terminal silicon devices that are configured in an inverse parallel arrangement to provide load current during both halves of the AC supply voltage. They are often used to control motor speed.
Varactor diodes are p-n junction diodes that are designed to act as a voltage controlled capacitance when operated under reverse bias.
Zener diodes are PN junction devices that are designed to operate in the reverse-breakdown region.
