MCT9001SD

Transistor, Photovoltaic Output Optoisolators Overview

The MCT9001SD is a dual-channel optocoupler from onsemi featuring NPN phototransistor outputs in an 8-SMD gull-wing package. It provides 5000 Vrms isolation voltage for robust signal transmission between isolated circuits. The device supports a maximum forward current of 60 mA with a typical forward voltage of 1V. Key electrical parameters include a minimum current transfer ratio of 50% at 5mA input, a maximum collector-emitter saturation voltage of 400mV, and a collector current rating of 30mA. Operating temperatures range from -55°C to +100°C, with rise and fall times of 2.4µs.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific ordering suffix (e.g., TR, CT) matches the required packaging format such as tape and reel or cut tape. Confirm RoHS compliance status and material declaration details through official onsemi documentation prior to procurement. Ensure the selected variant aligns with the intended surface-mount assembly process requirements.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required within a compact surface-mount footprint. Consider the 5000 Vrms isolation rating for high-voltage separation needs. Evaluate the 50% minimum CTR requirement against the driving circuit capabilities. Verify that the 30mA collector current limit suffices for the load application without exceeding thermal constraints.

Transistor, Photovoltaic Output Optoisolators Part Context

The MCT9001SD belongs to the MCT9001 series of transistor-output optocouplers. It complements other variants like the MCT9001S (MDIP package) by offering a surface-mount solution. This series is designed for general-purpose isolation tasks where space efficiency and reliable signal transmission are prioritized over higher speed or logic output types.
