Optoisolators are specialty devices that feature an electrical light source such as an LED, a photo detector, and a suitable passive electrical component such as a resistor. The optoisolator isolates an input electrical signal from the output and by using a light-based signal it prevents any interaction between the two electrically-driven signals.

The PC3H711NIP1B is a transistor, photovoltaic output optoisolator, making it ideal for a number of different applications, such as in regulated power supplies, circuit protection applications, full-wave or half-wave rectification, LED lighting and other motor control applications.

The PC3H711NIP1B optoisolator has a minimum lead spacing of 4.4 mm and a maximum lead spacing of 6.6 mm. It is constructed with a dielectric isolation barrier between the output transistor and phototransistor in order to prevent signal leakage between the two.

The PC3H711NIP1B also features a very high dielectric strength of up to 2000 Vrms between the input and output, as well as a wide voltage range for input and output of up to 30V. Additionally, the device has a very good switching speed, with a maximum rise time of up to 0.5µs. The PC3H711NIP1B is also very reliable due to its ESD protection for both the input and output junction.

When it comes to the working principle of this optoisolator the key component is the photoelectric effect. This phenomenon occurs when a voltage is applied to the photo-transistor of the device and a light source is applied to it. The light source causes electrons in the transistor to become energized and move. When this happens, an electric current is created in the transistor and this current is used to drive the output load.

If greater current or voltage control is needed, then the PC3H711NIP1B can be used with an external photovoltaic transistor. This allows for faster rise and fall times as well as greater current and voltage control. The PC3H711NIP1B can also be used to drive small relays or mechanical switches such as those used in motor control applications.

In summary, the PC3H711NIP1B is an optoisolator that is ideal for a number of different applications due to its high dielectric strength, wide voltage range, fast switching speed, and its ability to operate with photo-transistors for greater current and voltage control. It is constructed with a dielectric isolation barrier between the output transistor and phototransistor in order to prevent signal leakage, and it is exceptionally reliable due to its ESD protection for both the input and output junction.
