Optoisolators are electrical devices that use optical isolation to protect the circuit used to control the device and the circuit which is being controlled. The LIA130STR is a type of optoisolator in the transistor, photovoltaic output family. It is a small size, low current device with an insulative base. It is used for electrical isolation in wide variety of applications.

The LIA130STR can be used to control both DC and AC device. It functions by having the input signal optically transmitted across a gap in the device, usually by means of an LED. The large distance of the gap ensures the absolute electrical isolation between the input and output circuits as no electricity is able to pass. The light reaching the photodiode on the opposite side of the gap is then converted into an electrical signal which can be used to control the magnetic field of an electronic switch. The output can then be used to control a device.

The LIA130STR consists of an 6-pin dual-in-line package containing a light transmitting diode, an optically insulated photodiode, a voltage clamping circuit and a short-circuit protection circuit. The light emitting diode is used to transmit a photocurrent through the optically isolated gap to the other side of the gap and then on to the photodiode. The photodiode then converts the input signal into a voltage , which is then amplified and passes internally to the output leads.

The LIA130STR features a maximum allowable maximum power rating of 4.0 W @ 32 V, a maximum permissible photo-dynamic power of 60 mW, and a maximum direct input current of 10 mA. The device also features a total isolation resistance of 100Mohm and dielectric strength of 100 V/m for 10 ms. Its insulation resistance is greater than 100Mohm, and its insulation withstand voltage is 1000VAC.

The LIA130STR is suitable for a variety of applications. It is often used in automotive, medical, consumer appliance, home automation, and industrial control systems. Its small size and low power consumption also makes it suitable for battery powered applications. The device can be used for electrical isolation circuit in a variety of systems, from motion controllers for robots, to the control of AC and DC systems used in everyday appliances. It is also commonly used in sensing systems, such as pressure sensing systems, which require electrical isolation for safety.

The LIA130STR is well suited for many common applications due to its low power, small size, and excellent isolation. It is a reliable and cost-effective optoisolator which can be used in a variety of applications. Its wide operating temperature range of -20 °C to +85 °C, and excellent isolation capabilities make it a great choice for a variety of systems where optical isolation is required or desired.
