ISP847X

Optoisolators, or optocouplers, are used in many different applications to optically couple electrical systems. The ISP847X optoisolator is a transistor-photovoltaic-output (TPO) type of optocoupler that provides high isolation voltage, high switching speed, low current consumption, constructive thermal resistance, and low capacitance. The ISP847X is RoHS compliant and also UL1577 certified.

The ISP847X is a type 4N35 optoisolator with TVS (transient voltage suppression) protection to guard against ESD (electrostatic discharge) and surge events. It is packaged in a small 8-SO vedger size which makes it very suitable for applications with limited board space. It is a single-channel optoisolator with an LED input, an NPN phototransistor output, and an operating voltage of 6V to 20V.

The ISP847X includes an LED encased in an optically isolated quartz chip. When an input voltage is applied to the LED, it emits a high-intensity visible light which is directed to the integrated NPN phototransistor. The phototransistor is an NPN output type that provides an amount of current to the load proportional to the light intensity received from the LED.

The ISP847X also utilizes a unique, highly optimized manufacturing process that reduces the capacitance between the LED and phototransistor outputs. This makes the optoisolator more resilient to surge and ESD events. The optoisolator is also designed with a patented three-layer construction, which eliminates the need for extra insulation layers and improves performance.

The ISP847X optoisolator is well suited for a variety of applications. It can be used in AC/DC power supplies, controllers, electronic ballasts, motor control systems, medical devices, and any circuit that requires an optoisolator. It is an ideal choice for applications requiring a stable, reliable, and high-speed optoisolator along with TVS protection.

The ISP847X optoisolator has an excellent switching speed of 1ms and a relatively low current consumption of 20mA. The operating temperature range is -40°C to 85°C and its insulation resistance is greater than 10⁸ MΩ. The ISP847X is also easy to install due to its compact size and included mounting pins.

In conclusion, the ISP847X is a high-speed, high-isolation optoisolator with TVS protection. It is versatile and suitable for a variety of applications requiring optical isolation between the input and output circuits. The ISP847X offers a reliable and energy efficient solution for optically isolating circuits.
