The Isocom Components 2004 LTD IS202X is a series of single-channel optocouplers. Optocouplers (also known as optoisolators) are components that transfer electrical signals between two isolated circuits using light. They prevent high voltages or rapidly changing voltages on one side of the circuit from damaging components or interfering with signals on the other side. The IS202X series is a widely used general-purpose optocoupler.

Applications

• Microcontroller input isolation
• Power supply feedback control
• Digital logic isolation
• Noise isolation in industrial control systems

• Telecommunications equipment

Features

• High isolation voltage
• Current transfer ratio (CTR) options
• High speed switching
• Compact package
• UL, VDE, and CSA safety approvals (check specific model)
• RoHS compliant

Benefits

• Electrical isolation: Protects sensitive circuits from high voltages and transients.
• Noise immunity: Reduces noise coupling between circuits.
• Improved safety: Enhances safety in high-voltage applications.
• Flexible design: Offers various CTR options to meet different application requirements.
• Compact size: Saves board space.
• Meets industry safety standards: Ensures compliance with safety regulations.

Additional Details

The IS202X series generally consists of an LED on the input side and a phototransistor on the output side. When current flows through the LED, it emits light, which activates the phototransistor, allowing current to flow through the output circuit. Different versions of the IS202X are available with varying current transfer ratios (CTR), which is the ratio of the output current to the input current. The isolation voltage typically ranges from several kilovolts. The switching speed varies depending on the specific model but is generally suitable for many digital applications. Common package types include DIP and surface-mount options.
