Innoscience Technology has launched a 100V bi-directional GaN-on-silicon bi-directional transistor, intended to replace a pair of back-to-back mosfets for turning a power rail on and off.

In theory, the hundreds of photons, controlled by the triggering photon, could fan out and switch off hundreds of other transistors in an optical circuit.

Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team developed a thickness-controlled black phosphorous tunnel field ...

During the power-off transient, when the voltage goes below 4.63 V, the transistor switches off. This in turn de-energizes the relay, which then rapidly cuts off the power supplied to the relay coil.

Complementary circuits integrating plastic MEMS switches and organic transistors allow us to realize large-area, flexible, high-power applications.

Obviously, the function of muting circuits is to mute (kill) the audio signal. This can be done in a number of ways including switches, relay contacts, junction FETs, analog switches and bipolar ...

A new vertical architecture, in which the semiconductor is sandwiched vertically between the electrodes, boosts performance and could allow stacking transistors for dense electronic circuits.

Beyond Silicon Transistors: Switches Made of Carbon Thoughts on a Smarter Planet is a special blogger series in partnership with leading IBM experts.

A snubber circuit limits voltage spikes in power converters. Snubbers are also used in the output of Class-D audio amplifiers for the same reasons (Fig. 1). When the transistor you use to switch ...
