Optoisolators are devices that act as an electrical barrier between two circuits, creating a measure of electrical insulation between system components. One of the types of optoisolators is the transistor-photovoltaic output optoisolator, which employ a photovoltaic cell to alter the base-emitter voltage of a phototransistor. The LTV-355T-B is an example of this type of optoisolator.

The LTV-355T-B optoisolator is based around a Monolithic Silicon Detector Module (MSDM), which includes an infrared emitting diode and phototransistor in the same package. The emitter in the package creates an infrared signal which is received by the slave side phototransistor and used to switch it On or Off. This is the common “Minimum Pull-In” design, which ensures that even in long cables the optoisolator remains robust.

The MSDM optoisolator is powered by 5V DC and has a maximum operating temperature of 105°C. It is rated at 5A and 100V, with a typical On/Off ratio of 200:1. The package features an invert logic configuration, meaning that the output pin is high for an input signal of 0V and low for an input signal of 5V. On the master side of the optoisolator, the pinout is as follows: Input 0V, Output 5V, Ground 0V, Emitter Ground 0V, and Emitter 5V. The slave side of the device has four pins: Collector, Emitter, Ground, and Ground.

The LTV-355T-B optoisolator is ideal for use in many industrial and commercial applications. It is suitable for power control of motors, solenoids, and valves, and can be used to switch AC or DC, making it highly versatile. It can also be used to establish reliable, low-cost communications between local and remote components. In addition, it is ideal for noise filtering and computer interface applications.

The LTV-355T-B optoisolator is an efficient and reliable component ideal for a variety of applications. Its minimum pull-in design ensures reliable operation in long cable runs, while its 5A, 100V rating makes it suitable for use in both commercial and industrial applications. The device is powered by 5V DC and is easy to use, with an invert logic configuration and simple pinout. With its 5A, 100V rating and temperature rating of 105°C, the LTV-355T-B is an excellent choice for many applications.
