Optoisolators are devices which allow data to flow between two independent circuits while preventing them from affecting each other. The TLP385 is a type of optoisolator, also known as a transistor-photo-voltaic (TPV) output, which uses a photodiode to detect and transfer signals to another circuit. This article will explain the application field, working mechanism, and features of TLP385 optoisolator.

Application Field:

TPL385 optoisolator is designed for isolation sensing with high-speeds and excellent wave shape. It can be used in many applications, such as industrial automation, home appliances, automotive, and medical equipment. This optoisolator can be used in a wide range of digital and analog signals, including data transfer, level sensing, switch and relay control, proximity sensing, and voltage/current sensing.

Working Principle:

The TLP385 optoisolator consists of a photodiode and a phototransistor. When voltage is applied to the photodiode, it emits light which is picked up by the phototransistor. The phototransistor amplifies the light and sends a signal to the output of the optoisolator. The optical and electrical isolation provided by the optoisolator keeps the circuit which was detecting the signal isolated from the circuit which was sending the signal, thus allowing a safe data communication.

Features:

The TLP385 optoisolator is designed for maximum immunity to transient voltages and has a wide frequency response up to 100kHz. It also features fast emission and response times, up to 6000 Volts RMS isolation, high reliability, and peak output currents of up to 500mA. The optoisolator is also RoHS compliant and available in various package configurations.

In summary, the TLP385 optoisolator is a versatile device which provides isolation, voltage protection, and signal transfer in a variety of applications. It can be used in industrial automation, home appliances, automotive, and medical equipment, and can be used to transfer digital and analog signals. It features fast emission and response times, high immunity to transient voltages, and is RoHS compliant.
