Overview
The 4N30FSM is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a DC input type and a Darlington transistor output configuration housed in a 6-pin DIP package. The device provides an isolation voltage of 5300Vrms. Key electrical parameters include a maximum output voltage of 80V, a channel output current of 80mA, and a typical forward voltage (Vf) of 1.2V.
Feature Summary
- Darlington output structure for high current transfer ratio
- Unconnected base pin design to enhance noise immunity in high EMI environments
Applications
- Industrial control systems requiring galvanic isolation
- Signal transmission in high electromagnetic interference (EMI) environments
- General-purpose digital signal isolation circuits
Procurement Notes
Verify the specific suffix 'FSM' against official Isocom documentation to confirm package style and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for 6-pin DIP configurations. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.
Selection Notes
Select this component when high current drive capability is required from the phototransistor side due to the Darlington configuration. The unconnected base pin makes it suitable for applications where external noise susceptibility must be minimized without additional circuitry. Verify that the 80V output voltage rating meets the load requirements of the target circuit.
Part Context
Isocom Components 2004 LTD specializes in infrared optoelectronic devices with over 40 years of industry expertise. The company focuses on optocouplers and opto-switches, maintaining manufacturing capabilities through partnerships with contract manufacturers while retaining engineering and testing operations in the UK.
Replacement Considerations
The 4N30SMT&R is listed as a surface mount variant within the same product family. Verify pinout compatibility and package dimensions before substitution.
