IS201

Transistor, Photovoltaic Output Optoisolators Overview

The IS201 is a single-channel high-density phototransistor optically coupled isolator manufactured by Isocom Components 2004 LTD. It integrates an infrared light-emitting diode with an NPN silicon phototransistor within a 6-pin DIP package. Key electrical specifications include a maximum isolation voltage of 5300Vrms, a typical rise time of 2µs, and a typical fall time of 11µs. The device supports a maximum forward current of 60 mA and operates with a current transfer ratio ranging from 40% to 80%. It is designed for DC input applications and complies with RoHS standards.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., R for tape and reel) against the required packaging format. Confirm that the 5300Vrms isolation rating meets system safety requirements. Ensure the 60mA maximum forward current aligns with the driving circuit capabilities. Check for RoHS compliance documentation if environmental regulations apply. Validate the DIP-6 package dimensions against the PCB footprint design.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high-density mounting is required alongside robust galvanic isolation. The NPN phototransistor output is suitable for standard logic level interfacing. Consider the 40-80% current transfer ratio range for gain calculations in the application circuit. The 5300Vrms isolation provides significant margin for industrial noise immunity. Ensure the operating temperature range covers the intended environment.

Transistor, Photovoltaic Output Optoisolators Part Context

The IS201 belongs to Isocom's high-density phototransistor optocoupler family. It shares functional similarities with other single-channel isolators but distinguishes itself through its specific pin configuration and isolation voltage rating. This series is commonly used in applications requiring reliable signal transmission across isolated boundaries without electromagnetic interference.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Cross-reference with CNY17-1SMT&R for similar DIP-6 transistor output configurations. Verify pinout compatibility before substitution. Ensure replacement parts meet or exceed the 5300Vrms isolation requirement. Check that the current transfer ratio specifications are compatible with the existing circuit design.
