MCT2E

Transistor, Photovoltaic Output Optoisolators Overview

The MCT2E is a discontinued optoisolator manufactured by onsemi, distributed by Isocom Components. It features a single channel with a transistor output including a base terminal. The device provides 5300Vrms isolation voltage and operates within a temperature range of -55°C to 100°C. Key electrical parameters include a maximum forward current of 100 mA, a typical forward voltage of 1.25V, and a collector-emitter saturation voltage of 400mV. The unit supports a maximum output voltage of 30V and a continuous output current of 50mA. Switching times are typically 1.1µs for turn-on and 50µs for turn-off.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides galvanic isolation between input and output circuits using an infrared LED and phototransistor pair.
• Includes a dedicated base terminal on the output transistor to facilitate faster switching speeds or improved drive capabilities.
• Designed for through-hole mounting in standard 6-DIP packages.

Transistor, Photovoltaic Output Optoisolators Applications

• General-purpose digital signal isolation
• Microprocessor system interface circuits
• Solid-state relay driver applications

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify component status as the MCT2E is officially obsolete and no longer manufactured. Confirm availability through authorized distributors like Isocom Components. Ensure replacement parts meet original specifications for isolation voltage and package dimensions. Check datasheets for updated electrical characteristics if sourcing alternatives.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component for legacy designs requiring a standard transistor-output optocoupler with a base pin. Consider the 6-DIP package compatibility with existing PCB footprints. Evaluate the 5300Vrms isolation rating against system safety requirements. Note that newer variants may offer different packaging or enhanced performance metrics.

Transistor, Photovoltaic Output Optoisolators Part Context

The MCT2E belongs to the MCT2 family of optoisolators produced by onsemi. This series is widely used in industrial and consumer electronics for signal transmission across isolated boundaries. The specific MCT2E variant utilizes a DIP-6 package, distinguishing it from surface-mount counterparts like the MCT2ESR2VM.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitutes include the MCT2EM and MCT2EX. Verify pinout compatibility and electrical ratings when transitioning to these alternatives. The MCT2EM is available from onsemi, while the MCT2EX is offered by Isocom Components.
