4N30FSMT&R

Overview

The 4N30FSMT&R is a surface-mount optocoupler manufactured by Isocom Components 2004 LTD. It features a single channel with a Darlington transistor output and non-base configuration. The device provides an isolation voltage of 5.3 kVrms. Key electrical parameters include a maximum forward current (If) of 50 mA, a collector-emitter voltage (Vceo) of 80 V, and a typical switching time of 3.5 µs on and 95 µs off. It is housed in a 6-pin Surface Mount PDIP package.

Feature Summary

Utilizes a Darlington phototransistor output structure for high current transfer ratio capability.
Provides robust galvanic isolation between input and output circuits rated at 5.3 kVrms.
Designed in a compact surface-mount form factor suitable for automated assembly processes.

Applications

Industrial control systems requiring signal isolation
Power supply feedback loops
Microcontroller interface circuits

Procurement Notes

Verify the specific suffix 'FSMT&R' to confirm the tape-and-reel packaging format and the 'F' variant characteristics against standard 4N30 specifications. Ensure the procurement documentation explicitly states the manufacturer as Isocom Components 2004 LTD to distinguish from other vendors producing similar part numbers. Cross-reference the datasheet for any unique thermal or mechanical tolerances associated with this specific reel configuration.

Selection Notes

Select this component when a surface-mount solution is required for applications needing high gain via a Darlington output stage. The 5.3 kVrms isolation rating makes it suitable for mains-connected equipment. Consider the 50 mA maximum forward current limit when designing drive circuits. Verify that the 6-pin SMD footprint matches the PCB layout constraints compared to through-hole alternatives.

Part Context

This part belongs to the 4N30 series of optocouplers, which are widely used general-purpose devices. The 'FSMT&R' designation indicates a specific surface-mount variant produced by Isocom Components. While functionally similar to industry-standard 4N30 parts, manufacturers may have slight variations in electrical parameters such as CTR or switching speeds. Always consult the specific manufacturer datasheet for precise performance boundaries.

Replacement Considerations

Direct pin-compatible replacements include other 4N30-series surface mount optocouplers from different manufacturers. Verify that substitute parts meet the 5.3 kVrms isolation requirement and match the Darlington output configuration. Check if alternative packages offer improved thermal performance or higher current ratings if system requirements exceed the original specifications.
