OPI125

Overview

The OPI125 is a high-reliability photologic optically coupled isolator manufactured by TT Electronics/Optek Technology. It integrates a gallium aluminum arsenide infrared LED input with a push-pull, totem pole output stage. The device provides 15000 VDC isolation voltage and supports a data rate of 250 kbps. Key electrical parameters include a reverse voltage of 2 V, power dissipation of 200 mW, and a fall time of 100 ns. Operating temperatures range from -55°C to +85°C.

Feature Summary

High-voltage insulation capability for robust signal isolation
Push-pull output configuration for active drive performance
Integrated logic output for direct interface compatibility

Applications

High-reliability industrial control systems
Medical equipment requiring strict isolation
Automotive electronics applications

Procurement Notes

Verify the specific suffix variant (e.g., TX) against project requirements as specifications may vary. Confirm RoHS compliance status through official documentation. Ensure thermal management aligns with the 200 mW power dissipation rating. Check for end-of-life notices or obsolescence warnings prior to finalizing procurement plans.

Selection Notes

Select this component when high common-mode transient immunity and fast switching speeds are required. The push-pull output eliminates the need for external pull-up resistors in many logic interfaces. Consider the 15kV isolation barrier for safety-critical designs. Evaluate temperature stability if operating near the lower -55°C limit.

Part Context

This part belongs to the Optek Technology line of optoelectronic solutions, now under TT Electronics. The OPI series focuses on high-reliability optical coupling for demanding environments. These devices bridge the gap between standard optocouplers and specialized digital isolators.
