VOx619A series devices feature an infrared emitting diode that is optically coupled to a phototransistor detector. Optocouplers in the DIL-4 and LSOP-4 packages offer a high maximum rated isolation ...

The VOx619A series phototransistor optocouplers from Vishay Intertechnology, Inc. 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 ...

The optocoupler continues to evolve to meet increasingly stringent requirements emerging from power-conversion apps, where safety is a top design driver. This week's PowerBites focuses on some recent ...

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 ...

A difficult challenge in power-supply design is tailoring the response of the control loop. With the loads dynamically changing at a much higher frequency, the control loop has to keep up. To handle ...

Deep in the heart of your latest project lies a little silicon brain. Much like the brain inside your own bone-plated noggin, your microcontroller needs protection from the outside world from time to ...

Hybrid-electric vehicles must operate reliably under harsh conditions that demand special qualities on the part of power-conditioning electronics. Consider the electrical system for a hybrid-electric ...

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 ...

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 ...
