Overview
The OPI120 is a five-pin through-hole optocoupler from the OPI120 series, designed for DC input applications. It features a maximum forward voltage of 1.5V and supports a maximum input current of 150mA. The device provides an isolation voltage of 15kV dc, ensuring robust electrical separation between circuits. Typical rise and fall times are both 2μs, facilitating standard-speed signal transmission. The minimum and maximum current transfer ratios are specified as 20% and 50%, respectively. Operating temperatures range from -55°C to 100°C. The component holds UL recognition under file number E58730.
Feature Summary
- Provides high-voltage electrical isolation via a 15kV dc barrier.
- Utilizes a five-pin through-hole package for direct PCB mounting.
- Features fast switching characteristics with 2μs typical response times.
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in environments with high noise interference
- Power supply feedback loops
Procurement Notes
Verify that the specific order matches the manufacturer part number OPI120 and the Optek brand designation. Confirm compliance with the stated UL recognition file E58730 if regulatory certification is required for the end application. Ensure the procurement documentation explicitly lists the operating temperature range of -55°C to 100°C to guarantee suitability for the intended thermal environment.
Selection Notes
Select this component when a through-hole optocoupler with high isolation voltage is necessary. The 150mA maximum input current allows for flexible driver interface options. Consider the 2μs switching speed against system timing requirements. Verify that the 5-pin package dimensions fit the available PCB layout space compared to surface-mount alternatives.
Part Context
This device belongs to the OPI120 series manufactured by TT Electronics/Optek Technology. The series focuses on providing reliable optical isolation solutions using through-hole technology. The manufacturer specializes in optoelectronic components for industrial and general-purpose applications.
Replacement Considerations
Consult official datasheets for cross-reference models within the same series or equivalent isolation ratings. Verify pinout compatibility and current transfer ratio specifications before substituting.
