IC's and Semiconductor Parts & Devices

We have a wide selection of ICs and Semiconductors. Choose from communication encoders and decoders, logic, analog chips, microcontrollers, memory chips, transistors, diodes and more. Semiconductors are available in a variety of packages and manufacturers. A-Gem Supply also offers various price points to make sure you have the right product for the right build.

Semiconductors have a unique atomic structure that allows their conductivity to be controlled by stimulation with electric currents, electromagnetic fields, or even light. This makes it possible to construct devices from semiconductors that can amplify, switch, convert sunlight to electricity, or produce light from electricity.

Semiconductor devices are electronic components that exploit the electronic properties of semiconductor materials, principally silicon, germanium, and gallium arsenide, as well as organic semiconductors. Semiconductor devices have replaced thermionic devices (vacuum tubes) in most applications. We still sell old radio tubes, you can find a selection of classic components in our vintage section.


Many of our semiconductor parts and devices are used to build custom security systems. We are one of the leading burglar and fire alarm companies in Boise.


A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification, since it "straightens" the direction of current.


The most common function of a diode is to allow an electric current to pass in one direction (called the diode's forward direction), while blocking current in the opposite or reverse direction. Thus, the diode can be viewed as an electronic version of a check valve. Check our diodes for sale.

integrated Circuits

An integrated circuit (IC), sometimes called a chip or microchip, is a semiconductor wafer on which thousands or millions of tiny resistors, capacitors, and transistors are fabricated. An IC can function as an amplifier, oscillator, timer, counter, computer memory, or microprocessor.


transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. They start and stop the flow of a current, plus control the amount of the current.


A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. When you adjust the volume in audio systems, you are using a potentiometer knob or dial.
