Overview
The OPIA500BTR is a single-channel optoisolator manufactured by TT Electronics/Optek Technology. It features a transistor output configuration housed in a 5-SOP package. The device provides an isolation voltage of 3750Vrms between input and output circuits. Key electrical parameters include a minimum current transfer ratio of 19% and a maximum of 50%, both measured at a forward current of 16mA. This component is designed for applications requiring reliable signal transmission across isolated domains.
Feature Summary
- Provides galvanic isolation via infrared coupling between input LED and output phototransistor
- Delivers high isolation voltage rating for robust noise immunity
- Features standard transistor output for direct logic interface compatibility
Applications
- Industrial control systems requiring signal isolation
- Power supply feedback loops
- Microcontroller interface circuits with ground potential differences
Procurement Notes
Verify the specific suffix BTR indicates tape and reel packaging when ordering. Confirm the manufacturer designation as TT Electronics/Optek Technology to ensure authenticity. Check for obsolete status or lifecycle notices prior to finalizing procurement plans, as availability may be limited.
Selection Notes
Select this component when a single-channel isolation barrier with transistor output is required. Ensure the 3750Vrms isolation rating meets the system's safety requirements. Verify that the current transfer ratio specifications align with the driving circuit capabilities and load requirements.
Part Context
This part belongs to the Optek Technology line of optoelectronic components, now under TT Electronics. These devices are engineered for industrial and commercial applications where electrical isolation is critical for safety and signal integrity. The product range includes various isolators tailored for different speed and isolation voltage needs.
Replacement Considerations
Potential substitutes include other single-channel transistor output optoisolators with similar 3750Vrms isolation ratings and SOP-5 packages. Verify pinout compatibility and current transfer ratio ranges before substitution.
