QTM611T1

Logic Output Optoisolators Overview

The QTM611T1 is a logic output optoisolator manufactured by QT Brightek. It features a Mini-Flat package with five pins and supports a data rate of 10 Mbps. The device utilizes DC input and provides an open collector, Schottky clamped output. Key electrical specifications include a common mode transient immunity (CMTI) of 20 kV/µs and a maximum propagation delay of 75 ns for both low-to-high and high-to-low transitions. The unit offers isolation voltage ratings of 3750 Vrms.

Logic Output Optoisolators Feature Summary

• High-speed signal transmission capability at 10 Mbps
• Robust noise immunity with 20 kV/µs CMTI rating
• Integrated Schottky clamping on the output stage

Logic Output Optoisolators Applications

• Digital communication interface isolation
• Signal coupling in noisy industrial environments
• Logic level translation between isolated circuits

Logic Output Optoisolators Procurement Notes

Verify component status as obsolete before procurement planning. Confirm availability through authorized distributors or secondary market suppliers. Ensure storage conditions comply with MSL 3 requirements if handling existing stock. Validate pinout compatibility with target PCB footprint to prevent installation errors during integration.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required within a compact surface-mount form factor. The Mini-Flat package suits space-constrained designs. Consider the 10 Mbps speed limit and 20 kV/µs immunity against higher-performance alternatives if system demands exceed these thresholds. Verify input drive requirements match the DC input type specification.

Logic Output Optoisolators Part Context

This part belongs to the logic output optoisolator category from QT Brightek. It is designed for applications requiring galvanic isolation between digital logic circuits. The Mini-Flat packaging distinguishes it from standard DIP or SOIC optocouplers, offering a smaller footprint suitable for modern dense PCB layouts while maintaining necessary isolation barriers.

Logic Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require functional equivalence analysis rather than pin-for-pin substitution. Consult manufacturer archives for potential successor series.
