Optoisolators are devices that are designed to provide electrical isolation between two or more circuits by using light to pass signals between them. They can also be used as components in a variety of applications. The VO4158H-X007T is an optically coupled triac/SCR output isolator, and it is commonly used in applications that require a high degree of electrical isolation and the ability to control both AC and DC currents. The VO4158H-X007T combines a high isolation voltage, up to 4000 VACrms, and a current rated at 4 A.

The VO4158H-X007T is designed to provide protection against miswiring and surge damage by providing a barrier between two or more circuits. This isolator is typically used in motor control, safety circuits, signal switching, and other industrial applications. It can also be used as a standalone controller in circuits where signal isolation is necessary or desired. The VO4158H-X007T has a one-of-a-kind SCR operation that allows for an optimized performance even when driving heavy loads. This provides reliable and accurate control over a wide range of current loads, making it an ideal solution for demanding applications.

The working principle of the VO4158H-X007T is based on optically-coupled isolation. The core of the device is an injection-molded housing that houses a pair of light-emitting diodes (LEDs) and a complementary pair of photo-transistors. The inputs of the LED are connected to the signal that is to be isolated, and the LEDs are connected to the optical isolator output, which is then connected to the load. The LEDs emit light pulses that are received by the photo-transistors, which in turn, compete against each other and control the power switch. The respective photo-transistor will be activated first and control the power switch.

The VO4158H-X007T also features a built-in EMI filter, which helps to minimize EMF interference caused by large currents. This helps to provide full protection from electrical surges. Additionally, it has an operating temperature range of -40°C to +85°C, making it suitable for a wide range of applications. The VO4158H-X007T is UL approved, low-cost, and highly reliable, making it an ideal choice for any application requiring a cost-effective solution.

Overall, the VO4158H-X007T is a reliable optoisolator that can be used in a variety of applications requiring electrical isolation. It is a low-cost solution that provides reliable operation and protection against EMF interference. It is UL approved and features a wide operating temperature range, making it suitable for a variety of environments. With its high isolation voltage rating and current capacity, the VO4158H-X007T makes an ideal choice for demanding applications.
