SO-8-packaged device saves up to 40% space over two single-channel parts The PS9821 10-Mbit/s optocoupler is presented as the first such device to offer dual 3.3-/5.0-V operation from an 8-pin SO-8 ...

In LEDs heat and high currents hasten the dimming process which can lead to unreliable operation in LED-powered optocouplers. Some simple and straight-forward analysis will keep their light shining ...

When using an optocoupler in a linear application, you should consider its gain drift with temperature. Traditional single- and dual-transistor-output devices have a notable gain drift with ...

MALVERN, Pa., Feb. 25, 2026 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new series of phototransistor optocouplers that combine a high and linear current transfer ...

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 ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

Through light waves, optocouplers transfer signals of all types between components. Due to their mode of operation, they also provide electrical isolation and noise immunity not found in other ...
