On Oct. 3, 1950, three Bell Labs scientists received a patent for a "three-electrode circuit element" that would usher in the ...

This file type includes high resolution graphics and schematics. The spread of h FE values in a batch of transistors may be wide enough to cause unreliable performance during mass production of a ...

Transistors are the fundamental building blocks behind today's electronic revolution, powering everything from smartphones to powerful servers by controlling the flow of electrical currents. But ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

Foundries and packaging houses are wrestling how to control heat in the testing phase, particularly as devices continue to shrink and as thermally sensitive analog circuits are added into SoCs and ...

This is a simple circuit which checks the polarity of the component. If you connected in right polarity the LED in the circuit will glow and it will not glow when you connected in wrong way. This is a ...

A transistor is a key component in electronics, often used as a switch or to amplify a signal from a sensor. NPN (negative-positive-negative) transistors are the most used transistor. An illustration ...
