Optoisolators - Transistor, Photovoltaic OutputAn optoisolator is an electrical device that applies to the same basic principle as an opto-coupler, but with added benefits. Unlike an opto-coupler that utilizes a light source to transfer a signal from one circuit to another, an optoisolator is an electronic component that employs an electronic or photovoltaic output to transfer electrical signals. This type of device is the preferred choice for applications that need to combine electrical isolation with high speed data communication. The K825P optoisolator is one such device that offers performance and capabilities geared towards a wide variety of application fields. The K825P is an LED photovoltaic optoisolator with a transistor output. It features an open collector transistor output from a 4-pin DIP package, which provides 4000 Volts of maximum isolation. In addition, because it has a base emitter voltage of 1.5 Volts, K825P provides very high speed switching capabilities. The power supply voltage requirement for K825P is 5.0-24 Volts, and the operating temperature range is -40ºC to +85ºC, making it suitable for even the most extreme applications. This LED optoisolator features an output current of 90mA, and has a forward current of 2000 ΜA typical, with an off-state collector current of 100nA maximum. These operating characteristics make it an ideal candidate for a wide variety of applications.When it comes to the working principle of the K825P optoisolator, the idea is quite simple. When an electrical signal is applied to the optoisolator’s input side, the LED in the device turns on and emits a light visible to the phototransistor on the output side. This light induces a current in the phototransistor, which is then amplified and sent as output. This entire process results in complete electrical isolation between the input and output sides, which keeps any resulting interference to a minimum. Thanks to its combination of performance and durability, the K825P optoisolator is perfectly suited for a wide range of applications. These include low voltage current sensing, security systems, motor control, liquid level monitoring, and automatic adjustment systems. In addition, the device’s low on-resistance switching also makes it a favorable choice for industrial automation, and for applications where data transmission speeds and reliability are essential, such as in process control. Overall, the K825P optoisolator offers excellent performance in a small package, which makes it an excellent choice for everyday applications and specialized mission-critical projects alike. Thanks to its isolated circuit, fast response time, and its wide operating temperature range, the K825P ensures maximum performance in even the most challenging of environments.
