The IL755-2X007T is a single-channel, high-CTR transistor output optocoupler manufactured by Vishay. It provides electrical isolation between the input and output circuits, allowing for signal transfer without a direct electrical connection.

Applications

• Industrial control systems
• Motor control
• Power supplies
• Digital logic inputs
• Microprocessor system interfaces

Features

• High current transfer ratio (CTR)
• High isolation voltage
• Low saturation voltage
• Compact package
• High common-mode transient immunity

Benefits

• Improved system safety through electrical isolation.
• Protection of sensitive circuits from voltage spikes and surges.
• Efficient signal transfer with minimal signal loss due to the high CTR.
• Space-saving design due to the compact package.
• Reliable performance in noisy environments due to high common-mode transient immunity.

Additional Details

The IL755-2X007T consists of an infrared emitting diode (IRED) optically coupled to a silicon NPN phototransistor. When current flows through the IRED, it emits infrared light, which activates the phototransistor, allowing current to flow in the output circuit. The CTR is defined as the ratio of output collector current to input forward current. The high isolation voltage provides a significant safety margin against high-voltage transients. The typical operating temperature range is -55°C to +100°C. The package is lead-free and compliant with RoHS regulations.
