SFH619A-X007 Datasheet/PDFOptoisolators - Transistor, Photovoltaic Output
The SFH619A-X007 is a transoptor isolator with photovoltaic output in a compact 8-pin flat epoxy package. It contains an infrared light emitting diode and a phototransistor which is well suited for driving digital logic circuits such as an TTL. A wide supply voltage range of 2.2V to 36V makes it extremely versatile. It also has a near-zero holding current that makes it highly efficient since it draws very little current from the circuit. The SFH619A-X007 can also work at elevated temperatures, enabling it to be used in high-performance applications such as in automotive applications.
The SFH619A-X007 is primarily used to isolate two circuits when a high insulation voltage is required. It has a wide operating temperature range, from -40°C to +150°C, which makes it suitable for harsh environments. It has an insulation voltage of 3750Vrms, which guarantees reliable operation in circuit. It also has a wide reverse DC power supply range of 6V to 28V, making it suitable for a variety of applications.
The SFH619A-X007 wind isolator\'s working principle is based on the use of an infrared emitting diode and a NPN phototransistor output. The infrared emitting diode converts electrical power into infrared light, which is then detected by the phototransistor. The phototransistor output is basically a voltage signal based on the intensity of the infrared light. When the input signal is low, the light intensity is lower and the phototransistor produces a low voltage signal. When the input signal is high, the light intensity is higher and the phototransistor produces a higher voltage signal.
The SFH619A-X007 provides excellent noise rejection and excellent transient protection, making it ideal for applications where there is a risk of interference or power glitches. It is used in a variety of applications ranging from automotive electronics, white goods, and lighting control systems to industrial security systems and medical devices. It also provides a reliable interface for the various control systems such as power management and lighting control.
