Overview
The 4N29FSM is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features a Darlington transistor output configuration housed in a 6-pin DIP package. Key electrical specifications include a maximum DC forward current of 50 mA, a typical forward voltage of 1.2V, and a maximum collector-emitter saturation voltage of 1V. The device provides an isolation voltage of 5300Vrms and operates within a temperature range of -25°C to 100°C.
Feature Summary
- Darlington transistor output for high current gain
- High isolation voltage rating of 5300Vrms
- Wide operating temperature range from -25°C to 100°C
Applications
- General purpose signal isolation
- Microprocessor input/output interfacing
- Solid-state relay driver circuits
Procurement Notes
Verify the specific suffix 'FSM' against official Isocom Components datasheets to confirm pinout and packaging details. Ensure compatibility with existing circuit designs regarding forward current limits and saturation voltage requirements before procurement.
Selection Notes
Select this component when high current transfer ratio is required due to the Darlington output structure. Consider the 6-pin DIP form factor for through-hole mounting applications requiring robust mechanical stability and standard spacing.
Part Context
This part belongs to the general-purpose optocoupler family produced by Isocom Components 2004 LTD. The manufacturer specializes in infrared optoelectronic devices and often provides alternatives to discontinued industry-standard components. The 4N29 series is widely recognized for its reliability in isolation applications.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify pin compatibility and electrical parameters with alternative manufacturers if direct substitution is necessary.
