The H11B8153SD optoisolator is an isolating device designed to transfer electrical signals between two circuits in a way that is electrically isolated. It does this by using a photovoltaic or photo-conductive effect. The circuit contains one transistor and one photovoltaic cell. The optoisolator is most commonly used for controlling circuits from a distance or for providing a level of electrical noise immunity. It can also be used for remote control applications, where it will act as an input device to a switch or logic circuit.

Technical Specifications

The H11B8153SD optoisolator has an isolation voltage rating of 1000 Vrms, a transmission current of 0.5mA, a switching voltage of 4.7V, a trigger LED current of 10mW, and a collector-emitter voltage of 80V. It also has a response time of 3µs and a storage temperature range of -40°C to +125°C. The pinout consists of two (2) pins for the LED and two (2) pins for the transistor.

How it Works

The H11B8153SD optoisolator works by transferring electrical signals between two circuits using a photovoltaic or photo-conductive effect. This device contains one transistor and one photovoltaic cell. When the LED is driven with a current, it emits light, which is then converted into a voltage by the photovoltaic cell. This voltage is then used to trigger the transistor, which controls the circuit by allowing current to flow through it.

The optoisolator can act as either an input device or an output device. When used as an input device, it can be used to switch a circuit off and on from a distance. When used as an output device, it can be used to control an electronic circuit without the need for a physical connection.

Applications

The H11B8153SD optoisolator is most commonly used in motor control applications, due to its high isolation voltage rating. It can also be used in medical equipment, home appliances, and telecommunications equipment. It can also be used in industrial, automotive, navigation, and power control systems. Additionally, it can be used to detect position, pressure, temperature, and other physical parameters in various monitoring and control circuits.

Conclusion

The H11B8153SD optoisolator is an isolating device designed to transfer electrical signals between two circuits in a way that is electrically isolated. It is most commonly used for controlling circuits from a distance or for providing a level of electrical noise immunity. It can also be used in a variety of motor control, medical equipment, home appliance, telecommunications equipment, and industrial applications.
