TCMT4106

Overview

The TCMT4106 is a quad-channel transistor-output optocoupler manufactured by Vishay Semiconductor Opto Division. It provides electrical isolation with a rated voltage of 3750Vrms across four independent channels. The device features a 16-SOP surface-mount package, suitable for space-constrained designs. Key electrical parameters include a maximum collector-emitter voltage of 70V and a peak output current of 50mA per channel. The typical turn-on and turn-off times are 6µs and 5µs, respectively, while rise and fall times are specified at 3µs and 4.7µs. The unit operates within a temperature range of -40°C to 100°C.

Feature Summary

• Quad-channel configuration for multi-signal isolation in compact form factor
• High isolation voltage rating ensuring safe electrical insulation compliance
• Transistor output architecture supporting standard digital interface logic levels

Applications

• Industrial control system signal isolation
• Data communication interface protection
• Power supply feedback loop isolation

Procurement Notes

Verify the specific ordering suffix (e.g., TR, CT) to confirm packaging type before purchase. Ensure the component meets RoHS3 and REACH regulatory requirements for your target market. Confirm that the 28-week standard lead time aligns with project schedules. Validate that the 16-SOP footprint matches the PCB design constraints. Check for any recent Product Change Notices affecting manufacturing capacity or sourcing locations.

Selection Notes

Select this component when high-density isolation is required for multiple signals simultaneously. The quad-channel design reduces board space compared to discrete single-channel units. Consider the 3750Vrms isolation rating for applications requiring robust safety barriers. Evaluate the switching speed specifications against the system's data rate requirements. Ensure the operating temperature range covers the environmental conditions of the final assembly.

Part Context

This part belongs to the TCMT series of optocouplers from Vishay, designed for general-purpose isolation applications. The series offers various channel counts and output types to suit different circuit architectures. The TCMT4106 specifically addresses the need for multi-channel isolation in surface-mount designs, providing a balance between performance and physical size for modern electronic equipment.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameter margins if considering alternative quad-channel optocouplers from other manufacturers. Ensure any replacement maintains the same isolation voltage rating and package dimensions.
