Semiconductor devices relays

Every semiconductor device has an absolute maximum voltage rating that, unlike any typical mechanical relay, cannot be exceeded even momentarily — without possibly causing its immediate destruction. So most mosfets do not allow any latitude whatsoever, in terms of their voltage ratings. 

Printed circuit (PC) A conductive pattern on an insulating surface that may or may not include active devices such as relays (large) or semiconductor devices (small). If semiconductor devices are applied to the circuit pattern (appliqued), the circuit is called a hybrid microcircuit. 

At present the IV-VI series of semiconducting materials comprises a number of the most promising materials for IR applications [1-4]. An interest in these materials is primarily because they are narrow band gap semiconductors and therefore have the potential to be employed in devices as optically active components in the near-infrared (NIR) and infrared (IR) spectral region and are hence beneficial to applications for solar cells, detectors, telecommunications relays, etc. The interest in the IV-VI materials has also grown in recent years because of the observation that they are thought to demonstrate efficient multiple exciton generation (MEG) [3,5-7]. This has implications for the efficiencies of solar cells and other applications based on these materials, especially as it provides a means by which the Shockley/Queisser efficiency limit may be overcome.
