The H11B255S (TA) is an optoisolator with a transistor photovoltaic output. An optoisolator is a type of output device, enclosed in an insulated package allowing it to operate safely in harsh environments, that allows the isolation of two circuits. Its purpose is mainly to protect high-impedance circuits, such as those in microprocessors, from damage by voltage spikes and other forms of electrical interference.The H11B255S (TA) is a diode-uri device in which a LED receives signals from the input, photovoltaic output circuit draws power from the input and produces a signal based on the input voltage. The control signal is transferred from the input side to the output side without any electrical connection between them.The H11B255S (TA) operates by isolating the input side from the output side. This is done by the use of a photo diode and a high-frequency optical modulator. The photodiode converts the electric signal coming from the input side into an optical signal, which is then transferred to the output side via an optical conversion process.The optical projection of the signal generated by the photodiode is then modulated by a high-frequency optical modulator. This modulation allows for a more efficient transfer of the signal to the output side without any loss of accuracy.The most important feature of the H11B255S (TA) is that it is an optically-isolated device, which allows for complete electrical isolation between the input and the output sides. This provides comprehensive protection against electrical surges, electrostatic discharge, and similar high-voltage disturbances.The H11B255S (TA) also has a high power handling capacity, which makes it suitable for applications that require a heavy-duty performance. This feature makes the H11B255S (TA) ideal for industrial and medical applications, such as high-power LED lighting, medical imaging, and so on.The H11B255S (TA) also features a wide range of operating temperature from -40°C to + 85°C. The wide temperature range ensures that the optical output is not affected by extreme temperatures and thereby extends the lifespan of the device.The H11B255S (TA) is also highly reliable, with an MTTF (Mean Time To Failure) rating of 100 thousand hrs, ensuring smooth operation over long-term use. In conclusion, the H11B255S (TA) is an optoisolator with transistor photovoltaic output designed for applications that require reliable electrical isolation from external sources. With its high power handling capacity, wide operating temperature range, and long MTTF, the H11B255S (TA) is an ideal choice for applications sensitive to electrical interference.
