The EL3H7(B)(TA)-G is a Phototransistor Output Optocoupler manufactured by Everlight Electronics Co Ltd. This optocoupler provides electrical isolation between input and output circuits using an infrared LED and a phototransistor. This allows for signal transfer without a direct electrical connection, protecting sensitive circuits from high voltages and noise.

Applications:

• Programmable Logic Controllers (PLCs)
• Industrial Control Systems
• Power Supplies
• Motor Control
• Data Transmission

Features:

• High Isolation Voltage
• Compact Package
• High Current Transfer Ratio (CTR)
• Low Input Current
• RoHS Compliant

Benefits:

• Provides Electrical Isolation and Safety
• Protects Microcontrollers and Sensitive Circuits
• Reduces Noise and Ground Loops
• Enables Signal Transmission Across Different Voltage Levels

Additional Details:

The EL3H7(B)(TA)-G Optocoupler uses an infrared light-emitting diode (LED) to transmit a signal to a phototransistor. When current flows through the LED, it emits light, which activates the phototransistor on the output side. The amount of current that flows through the phototransistor is proportional to the current through the LED, allowing for signal transfer. The 'B' designation may refer to a specific CTR range. The (TA) indicates tape and reel packaging. The -G indicates it is a Green product and RoHS compliant. It is important to consult the manufacturer's datasheet for specific values of CTR, isolation voltage, forward voltage, and other electrical characteristics to ensure proper application and optimal performance within the intended circuit. Ensure appropriate current limiting resistors are used on the input side to prevent damage to the LED.
