TCET1100G

Optoisolators - Transistor, Photovoltaic Output

The TCET1100G optoisolator, known as an optocoupler, is a modern interface technology used in various applications to isolate a device electrically from its environment. It is widely used for electronic applications such as motor controls, signal transmission and noise reduction. The primary purpose of an optocoupler is to provide electrical isolation between the input and the output while preserving the signal integrity and preventing electrical interference.

Optocouplers are typically composed of two parts, a light-emitting diode (LED) and a photosensitive device such as a photodiode, phototransistor or photo-VI. The LED is driven by current when a voltage is applied to its input terminal, and emits light, which is received by the photosensitive device. The photosensitive device then produces a current output, which in turn is applied to an external circuit or device.

The TCET1100G optoisolator is a direct-coupled isolation device utilizing a phototransistor output, which is coupled directly to the LED. It is designed to provide reliable, high-speed, low-amplitude signal transmission from one component to another within an application. The device can be used to connect digital, analog, and mixed-signal circuits to other components. It can also be used to reduce noise and EMI caused by power line transients and other environmental factors.

The device features a negative-going LED input, which is designed to be driven directly from a positive voltage source. When voltage is applied, the LED emits light, which is shone onto the phototransistor. The phototransistor then absorbs this light to generate current. This current is then used to drive the output circuits of the device.

The TCET1100G optoisolator is ideal for applications that require high-speed, low-power, and reliable signal transmission. It is well-suited for applications such as motorcontrols, robots, communication systems, diagnostic equipment, automotive systems, and electronic equipment. The device has a wide input voltage range and low input capacitance, which make it ideal for high-speed data transfer. It is also capable of operating at frequencies up to 60 MHz and is highly resistant to ESD, RFI, and EMI.
