MCT2E300

Transistor, Photovoltaic Output Optoisolators Overview

The MCT2E300 is a high-voltage optoisolator manufactured by onsemi, featuring a single channel with a transistor output that includes a base terminal. It provides an isolation voltage of 5300Vrms and operates within a temperature range of -55°C to 100°C. The device utilizes a 6-DIP package for through-hole mounting. Key electrical specifications include a maximum collector-emitter voltage of 30V, a DC forward current limit of 100mA, and a typical forward voltage of 1.25V. The unit supports a collector current of 50mA with a minimum current transfer ratio of 20% at 10mA input. Switching characteristics are defined by typical turn-on and turn-off times of 1.1µs and 50µs, respectively.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix designation when sourcing, as it may indicate packaging variations or environmental compliance status distinct from the base part number. Confirm availability status, as this component has been identified as obsolete in certain distributor catalogs. Ensure the selected variant matches the required lead-free and RoHS compliance standards for your manufacturing process. Cross-reference the manufacturer's official documentation for the most current lifecycle and replacement recommendations.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a standard transistor output optocoupler with an exposed base pin is required for flexible circuit design. The 5300Vrms isolation rating makes it suitable for applications demanding significant potential difference separation. Consider the 6-DIP package dimensions for PCB layout constraints. Evaluate the switching speed parameters against your system's timing requirements, as the turn-off time is relatively slow compared to high-speed logic isolators.

Transistor, Photovoltaic Output Optoisolators Part Context

The MCT2E300 belongs to the MCT2 series of optoisolators produced by onsemi. This series is characterized by its use of silicon planar technology for the LED emitter and phototransistor detector. The '300' suffix typically denotes a specific tape-and-reel or bulk packaging configuration rather than a functional change in the semiconductor die itself. It serves as a legacy component in onsemi's portfolio for general isolation needs.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Direct substitute part numbers include MCT2EM from onsemi and 4N25-000E from Broadcom Limited. These alternatives offer similar functional characteristics and pinouts. Verify mechanical compatibility and electrical parameter equivalence before finalizing any substitution in existing designs.
