Overview
The OPIA817ATUE is a transistor output optoisolator manufactured by TT Electronics/Optek Technology. It features a single channel with a Photodarlington output configuration housed in a 4-SMD package. The device provides an isolation voltage of 5000 Vrms and supports a maximum collector current of 80 mA. Key electrical parameters include a forward current of 50 mA, a forward voltage of 1.2 V typical, and a collector-emitter saturation voltage of 200 mV maximum. The unit operates within a temperature range of -30°C to +100°C and has a power dissipation rating of 200 mW.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits for signal transmission.
- Utilizes a Photodarlington output structure to deliver high current transfer ratios.
- Designed for surface-mount installation to facilitate automated PCB assembly processes.
Applications
- Industrial automation control systems requiring circuit isolation
- General-purpose signal coupling in electronic interfaces
- High-reliability modules for industrial environments
Procurement Notes
Verify the specific suffix 'TUE' corresponds to the tube packaging format, as other suffixes like 'TRE' indicate tape and reel options. Confirm RoHS compliance status and lead-free certification details directly from the manufacturer's documentation before procurement. Ensure the 4-SMD footprint matches the target PCB design constraints.
Selection Notes
Select this component when a high-current Darlington output is required for driving loads directly without additional amplification. The 5000 Vrms isolation rating makes it suitable for applications demanding significant noise immunity. Consider the 4-SMD package size for space-constrained designs compared to through-hole alternatives.
Part Context
This part belongs to the Optek transistor output optocoupler family produced by TT Electronics. These devices are engineered for robust performance in industrial settings. The OPIA817ATUE specifically offers a surface-mount variant, distinguishing it from DIP or other package types within the broader product line.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs using equivalent specifications such as CTR, isolation voltage, and package dimensions.
