An isolator is a device designed to provide galvanic isolation between circuits. It ensures that two or more electrical circuits are operating independently of each other by preventing any current flow between them. The HCPL-3140#560 isolator is a single-channel opto-isolator with a variety of features, making it an ideal choice for several applications.

The HCPL-3140#560 provides isolation of up to 1000 Vrms and has a propagation delay of 4.0 ns, making it an ideal choice for applications requiring a high degree of electrical isolation such as:

• Medical Devices
• Aerospace and Defense
• Industrial Automation
• Power Electronic Control
• Measurement and Control

The HCPL-3140#560 can be used for both automotive and consumer applications due to its capability of blocking a DC input signal up to 40 Vrms and providing up to 2 A current output, with 10 mΩ on-resistance.

The HCPL-3140#560 isolator consists of a light transmitting material and a phototransistor, both of which work together to provide isolation between electrical circuits. The light-transmitting material is composed of two parts: An emitter and a detector. The emitter is a light emitting diode (LED) and is used to convert electrical energy into light energy. The detector is a phototransistor, which is used to convert the light energy back into electrical energy.

When the LED is driven in the forward direction, a small current passes through it, which in turn causes the LED to emit light. The light is then detected by the phototransistor, which then converts the light energy into a small electrical current, enabling electrical isolation between circuits.

The HCPL-3140#560 also provides an overvoltage protection of up to 40 Vrms, allowing it to safely handle higher voltage signals, protecting the circuits from damage due to overvoltage. It also has a dielectric strength of 1000 Vrms and a hot plugging capability of up to 70,000 insertions.

The HCPL-3140#560 offers high isolation and signal protection, and is ideal for applications requiring high isolation, fast response time, and minimal losses. It is capable of providing isolation of up to 1000 Vrms and performing up to 2 A current output with 10 mΩ on-resistance.
