OPI7010

Overview

The OPI7010 is a transistor output optocoupler manufactured by TT Electronics/Optek Technology. It consists of an infrared emitting diode coupled to an NPN silicon phototransistor within a single package. The device features a maximum collector-emitter voltage of 30 V and a maximum collector current of 30 mA. It operates with a DC forward current up to 50 mA and provides a minimum current transfer ratio of 20%. The unit supports a reverse voltage of 2 V and has a maximum collector-emitter saturation voltage of 400 mV.

Feature Summary

• Integrates an infrared LED with an NPN silicon phototransistor for signal isolation
• Provides electrical isolation between input and output circuits
• Designed for general-purpose switching and logic interface applications

Applications

• General-purpose signal isolation in electronic circuits
• Logic level interfacing between different voltage domains
• Switching applications requiring galvanic isolation

Procurement Notes

Verify the specific package variant and suffix codes against the manufacturer's latest documentation, as Optek products may have multiple packaging options or revision histories. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability can vary. Ensure the selected component matches the required pin configuration and thermal characteristics for the intended PCB layout.

Selection Notes

Select the OPI7010 when a low-cost, general-purpose optoisolator with a transistor output is required. Consider the 6 kV isolation rating and the 20% minimum CTR for basic switching tasks. Evaluate the operating temperature range of -40°C to +85°C against environmental conditions. Compare performance metrics such as propagation delay and saturation voltage if high-speed or low-voltage drop applications are critical.

Part Context

The OPI7010 belongs to the OPI7002 family of optically coupled isolators from TT Electronics/Optek Technology. These components are designed to provide reliable electrical isolation using an infrared LED and a silicon phototransistor. The family is commonly used in industrial and consumer electronics where cost-effective isolation solutions are needed for data transmission or power supply feedback loops.
