TLP185 (GB-TPR, SE application field and working principle) is an optoisolator belonging to the Transistor, Photovoltaic Output type. Optoisolators are devices in which an input signal is converted to an output signal using one or more components including a photovoltaic cell. In the case of TLP185 (GB-TPR, SE) this cell is a photodiode that is triggered by the input signal. The photodiode then generates a current, which carries the output signal.

Generally speaking, optoisolators are used in applications where it is necessary to isolate the input and output signals. This is usually achieved by using a photodiode or light-emitting diode to isolate the signals, since they are not directly connected to each other. For example, in industrial automation applications, optoisolators can be used to design systems that can be installed in hazardous areas with the highest level of safety. In this way, dangerous signals can stay isolated from the system.

TLP185 (GB-TPR, SE) provides a sharp rise time and fast fall time for a wide range of input signals. The device also provides low power consumption and high level of insulation. The operating voltage range of this device is from 3.0 to 16 V, while the output current can be up to 2 mA. The maximum power dissipation of TLP185 (GB-TPR, SE) is maximum 180 mW, and the operating temperature ranges from -20 to +85 °C.

The working principle behind TLP185 (GB-TPR, SE) is relatively simple. It consists of a photodiode, phototransistor and an LED. When the input signal is applied, the LED emits light. This light is picked up by the photodiode and converted into a current which is then amplified by the phototransistor. The amplified signal is then collected at the output circuit.

The phototransistor used in this device is of a specific design to prevent saturation of the transistor and to ensure the stability of the signal. The collector, emitter and base of this component are connected to separate pins in order to reduce the input capacitance and maintain the insulation between the input and output circuits. Furthermore, the emitter of the transistor is located below the photocell in order to reduce the effect of the ambient light level.

TLP185 (GB-TPR, SE) is a widely used optoisolator in industrial, automotive and telecommunications applications. It offers a combination of fast switching time, high insulation and low power consumption. The signal isolation provided by this device is excellent, making it ideal for applications where safety is a priority. The device’s rugged design makes it reliable in various harsh environments.
