Switching power supplies, operating directly from input power lines, are generally required to have their outputs galvanically isolated from the input, in order to reduce the danger of electrical ...

Würth Elektronik has released a detailed and thoughtful app note on using opto-couplers, particularly ‘817’ types. AN0007a* ‘Understanding phototransistor optocouplers’ goes deep into analogue and ...

Optocouplers provide high-voltage isolation between a low-voltage device like a microcontroller or a pulse-width modulation (PWM) generator and a high-voltage device like an intelligent or integrated ...

This white paper discusses the use of hermetic optocouplers in military and space electronics applications. The use of hermetic optocouplers provide a highly reliable result compared to its plastic ...
