4N35 Optocoupler Phototransistor IC

The 4N35 is a general-purpose optocoupler designed to provide electrical isolation between two circuits. It consists of a gallium arsenide infrared LED and a silicon phototransistor, allowing for efficient signal transfer while maintaining isolation.

Key Features:

• Gallium Arsenide Infrared LED: Emits infrared light to control the phototransistor.
• Silicon Phototransistor: Converts the received infrared light into an electrical signal.
• High Isolation Voltage: Ensures electrical separation between input and output circuits.
• Wide Operating Temperature Range: Suitable for various environments.
• DIP-6 Package: A common package type for discrete semiconductors, providing a standard pinout and mounting configuration.

Specifications:

• Input Current (If): 10mA (typical)
• Output Current (Ic): 50mA (typical)
• Isolation Voltage: 5000VRMS
• Forward Voltage (Vf): 1.5V (typical)
• Collector-Emitter Saturation Voltage (Vce(sat)): 0.4V (typical)
• Package: DIP-6

Applications:

• Signal isolation
• Noise suppression
• Power supply control
• Motor control
• Industrial automation
• Medical devices
