Optoisolators are electronic devices which provide electrical isolation between circuits. The TLP759 (D4, J, F) optoisolator is a type of transistor-photovoltaic (TPO) optoisolator. TPO optoisolators are designed to isolate circuits by using a light-emitting diode (LED) to drive a PNP-type transistor. The photo-voltaic effect causes the LED to emit electrons, which are then collected by the transistor and collected by the collector terminal. The resultant current flow creates a zero-impedance separation between the input and the output circuits.

The TLP759 optoisolator has many advantages over other types of optoisolators; it has high isolation resistance of 1000Vrms, fast response time of 5 to 10 nanoseconds, and its isolated output stage can provide high current drive up to 25 MA. Additional features of the TLP759 include an on-chip resistor that helps minimize the LED’s loading effect and reduce power consumption, and a maximum collector-emitter voltage of 1.6 A.

The TLP759 is often used in automotive, industrial, and control applications, as well as in communications, medical, and telecom applications. For example, in automotive applications the optoisolator can be used to isolate the power circuits in the engine control unit, to reduce electrical noise and prevent unwanted current. In industrial applications, the TLP759 can be used to provide optical isolation for process instrumentation, reducing susceptibility to electrical noise and providing electrical control points with higher levels of isolation. The medical field employs optoisolators to ensure the safety of medical devices, such as pacemakers and other implantable devices, by isolating sensitive components from outside electrical interference. The telecom industry makes use of the TLP759 optoisolator for electro-magnetic interference (EMI) shielding of communication systems, while providing high-sensitivity coupling between radio-frequency components.

The TLP759 optoisolator is a simple yet effective device which can provide excellent isolation between circuits while reducing the effect from external electrical noise. Due to its high isolation resistance and fast response time, it is ideal for applications requiring reliable voltage isolation and improved control. The optoisolator is also able to reduce power consumption, enabling it to be used in power-sensitive applications, such as in medical and telecom systems.
