Applications

• General-purpose digital signal isolation
• Microcontroller interface protection
• Industrial control circuit isolation

Procurement Notes

Verify the specific suffix 'TRE' indicates tape and reel packaging when sourcing. Confirm the obsolete status with the manufacturer or authorized distributors prior to finalizing procurement plans. Ensure compatibility with existing surface-mount reflow profiles and handling procedures for small outline packages.

Selection Notes

Select this component when 5000Vrms isolation is required in a minimal footprint. The transistor output suits low-speed digital switching tasks. Consider thermal management within the specified operating range. Verify that the 4-SMD package aligns with the target PCB layout constraints and automated assembly capabilities.

Part Context

This part belongs to the Optek optoisolator family, designed for reliable electrical isolation. It serves as a discrete solution for separating ground planes in mixed-signal systems. The transistor output configuration offers a balance between speed and cost for basic isolation needs.
