TLP2161(F)

Optoisolators are widely used in digital and analog circuit protection. They provide safety measures by creating an optical transmission barrier between the high voltage power source and the logic circuit. Optoisolators can be generally divided into two varieties: logic output and analog output. The TLP2161(F) optoisolator belongs to the former and is typically used to isolate logic circuits or other low-voltage components from high voltage, high current or high noise in power drive applications.

The TLP2161(F) features a logic output configuration in which signal transmission is based on an optical transmission barrier between the input and output sides of the device. It features a built-in high-input impedance ohmic photocoupler, which consists of an infrared LED and a phototransistor. The LED, which is connected to the input side of the device, emits infrared light through a crystal window when a voltage is applied to the input side. Meanwhile, the phototransistor picks up the signal on the output side and responds by changing its voltage. Depending on the configuration, the phototransistor will either switch on and off or provide a higher or lower voltage output.

The TLP2161(F) is commonly used in a range of applications such as power electronics, motor control, and lighting control. It can be used to eliminate surge voltage on the input side, isolate logic signals of different domains, prevent high voltage from entering the logic circuit, and isolate logic signals from noise in power lines. Additionally, it is also used to provide an electrical disconnection on the output side. The device is available with a single or dual channel input and output voltage of 3.3V or 5V. Furthermore, it has a surge voltage withstand capacity of 2 kV and isolation voltage of 2600VAC. The isolation voltage rating allows the TLP2161(F) to effectively prevent noise from entering the sensitive components.

TLP2161(F) optoisolators are commonly used in applications such as industrial sensors, microprocessor measurement and control, and PLCs. In such applications, they provide signal isolation as well as noise isolation, eliminating ground loops and preventing noise transmission between logic circuits and high voltage components. Additionally, they can provide a level shifting in logic signal voltages, allowing logic signals to be connected between circuits with different operating voltages.

In summary, TLP2161(F) optoisolators are highly valued for their ability to provide optical transmission barriers between the input and output sides of the device. They are suitable for a range of applications where there is a need to protect the logic circuit from high voltage, high current and high noise on the power drive side. The devices feature a high-input impedance ohmic photocoupler, with a single or dual channel input and output voltage of 3.3V or 5V. The surge voltage withstand capacity and isolation voltage of the device provide effective protection to the logic circuit from noise.
