ElFys has launched circular four-quadrant near-infra-red detector with a 14mm diameter active area, leading to 38.5mm2 of sensing surface in each quarter. Named QPD-385-Y, the sensor’s dark current is ...

Before today, we probably would have said that scratch-built relay computers were the sole domain of only the most wizardly of graybeards. But this impressive build sent in by [Will Dana] shows ...

When pin 4 of the LM555 is triggered (by shorting it to ground ... A transistor Q1 acts as a switch an ensures sufficient drive current is provided to the relay. Diode D1 acts as a flyback diode which ...

Toshiba Electronics has introduced a 60V 1A single-contact photo-relay in a 2.6 x 7mm 4pad SO4 package. Called TLP3640A, it can switch 60Vdc or 60Vac peak, with a typical on-resistance of 0.14Ω and ...

This design enhances carrier injection efficiency and reduces leakage currents, which are critical for improving the overall performance of high-power laser diodes[4]. Lastly, the study of quantum ...

Learn more about whether Fabrinet or Littelfuse, Inc. is a better investment based on AAII's A+ Investor grades, which compare both companies' key financial metrics.

The premature edge breakdown of the avalanche photon diode (APD) is an important factor that affects the single photon counting of the avalanche diode [4]. Guard ring is an effective method to prevent ...

By using clever coil driving, we can make even more energy savings. The values shown will switch the relay with a very short turn on delay (values given in brackets will produce a turn on delay of ...
