Choice of a Single and Dual LED

Phototransistor or Photo Darlington Sensor

Low-cost plastic Dual-In-Line (DIP) package

Agency Approvals:

Description:

The OPIA series optocouplers are designed for applications that use an analog output (Phototransistor or

Photodarlington) in a surface mount package. A wide selection of configurations are available. With typical

isolation voltage of 2,500 or 3,750 Volts(RMS), these products meet typical power system isolation requirements.

Theory of operation: The LED transmitter is used to illuminate the Photo sensor providing electrical isolation

between two power systems while maintaining the ability to transmit information from one power system to the

other. In many applications, analog signal levels may be required to be transmitted between two power systems

while maintaining isolation between the power systems up to 3,750 Volts(RMS). A variety of LED and photo

sensor configurations are available depending on the system requirements.

The Current Transfer Ratio (CTR) is determined using the output current and input current for analog photo

sensors. CTR ratios can range from as low as 5 to over 9,000 depending on the device.

Photosensor − Current 20mA

CTR =

*100 = 200

LED − Current

10mA

All SMD products are shipped in a shipping tube with “TR” identified on the end of the part number.

Example: OPI401ATRE is a 4-Pin SMD shipped in tape and reel (TR)

Applications:

• High voltage isolation: 2,500 or 3,750 Volts(RMS)

• PCBoard power system isolation

• Industrial equipment power isolation

• Medical equipment power isolation

• Office equipment
