ON Semiconductor 4N27VM Optocoupler

The ON Semiconductor 4N27VM is a versatile optocoupler device that provides an effective solution for electrical isolation requirements in various electronic applications. This optoelectronic component is designed to transfer electrical signals between two isolated circuits through light waves, ensuring that high voltages cannot directly flow from one side of the circuit to the other. As a result, the 4N27VM is an ideal choice for protecting sensitive electronics from voltage spikes and surges.

Featuring a gallium arsenide infrared LED and a silicon phototransistor, this optocoupler allows for a direct current transfer ratio in a compact DIP-6 package. The 4N27VM has been engineered to deliver high performance with a wide current transfer ratio (CTR) range, typically between 20% to 300%, which provides designers with flexibility in their circuit designs.

Key specifications of the 4N27VM include:

• Input-to-output isolation voltage (VISO) of 5000Vrms, which offers excellent insulation and stability.
• Operating temperature range from -55°C to +100°C, making it suitable for industrial environments.
• Forward current (IF) of 60mA and collector-emitter voltage (VCEO) of 30V, ensuring compatibility with standard digital logic levels.
• Response times are fast, with a typical rise time of 2µs and fall time of 2µs, which is essential for applications requiring quick signal processing.

The 4N27VM is commonly used in microprocessor inputs, digital logic inputs, power supply isolation, and analog signal isolation. Its ability to provide electrical insulation while allowing signal transmission makes it a critical component in preventing ground loops and common mode noise that can disrupt or damage sensitive electronic equipment.

ON Semiconductor's commitment to quality and reliability is evident in the 4N27VM, which is UL recognized and meets or exceeds industry standards for safety and performance. Whether you're designing a new circuit or looking to retrofit an existing system, the 4N27VM offers a reliable and cost-effective solution for your isolation needs.
