Optoisolators, also known as optocouplers, are widely used in electronic devices to provide electrical isolation. A popular optoisolator is the TIL111SR2VM, which uses a combination of a light-emitting diode (LED) and a silicon bilateral switch to provide electrical isolation between two circuits. This type of optoisolator is classified as a Transistor, Photovoltaic Output optoisolator. In this article, we will explore the application field and working principle of the TIL111SR2VM.

The TIL111SR2VM optoisolator can be used in a variety of applications, including microprocessor-based systems, power supplies, and motor control systems. The device can be used to provide electrical isolation between a high-voltage circuit and a low-voltage circuit. It can also be used for input signal isolation when communicating between two circuits.

The optoisolator is comprised of two parts, the LED and the silicon bilateral switch. The LED is the light-emitting diode, and the silicon bilateral switch is a type of transistor. The LED is placed inside a light-tight package and receives its power from the input side of the optoisolator. The LED emits light when its anode is positively charged. The emitted light strikes the photosensitive diode, which in turn triggers the silicon bilateral switch. When the switch is triggered, it closes and allows current to flow through the output side of the optoisolator.

The TIL111SR2VM optoisolator provides a maximum isolation voltage of 500 VAC peak and is available in a variety of packages, including DIP, SMD, and through-hole. The device has a maximum LED forward voltage of 8 VDC and a maximum leakage current of 0.8mA. The device has a total capacitance of 1000pF and an impedance of 1.8KOhm.

Overall, the TIL111SR2VM optoisolator is a reliable and versatile device that can be used in a variety of applications. The device utilizes a combination of an LED and a silicon bilateral switch to provide electrical isolation between two circuits. The device provides a maximum isolation voltage of 500 VAC peak and has a maximum LED forward voltage of 8 VDC.
