Overview
The 4N32G is a single-channel optocoupler manufactured by Isocom Components 2004 LTD. It features an infrared LED input coupled to a Darlington transistor output with a base lead for improved switching speed. The device provides high isolation voltage of 5300Vrms and supports a maximum collector current of 50mA. It operates with a typical forward voltage of 1.2V and utilizes a standard 6-pin DIP package for through-hole mounting.
Feature Summary
- Integrates an infrared emitting diode with a photodarlington output structure
- Includes a dedicated base terminal to facilitate faster turn-off times
- Provides robust electrical isolation between input and output circuits
Applications
- General-purpose signal isolation in digital communication interfaces
- Switching applications requiring moderate current drive capabilities
- Industrial control systems needing galvanic separation
Procurement Notes
Verify the specific suffix (e.g., G, FSM) against your bill of materials, as packaging and pin configurations may vary. Confirm that the Darlington output type matches your circuit requirements rather than a standard phototransistor. Ensure the 6-pin DIP form factor fits your PCB layout constraints before ordering.
Selection Notes
Select this component when a higher output current capability than standard phototransistors is required. The integrated base lead allows for external biasing to optimize switching performance in high-speed digital applications. Consider the 5300Vrms isolation rating for safety-critical designs involving mains or industrial voltages.
Part Context
Isocom Components 2004 LTD specializes in infrared optoelectronic devices, offering replacements for legacy industry-standard components. The 4N32G belongs to their range of optocouplers designed to meet global manufacturing standards. The company focuses on providing flexible manufacturing options and specialized parameter selections for diverse circuit design needs.
Replacement Considerations
The 4N32FSM is a documented variant from the same manufacturer. Verify if the FSM suffix indicates a specific tape-and-reel packaging option or minor mechanical difference compared to the standard DIP version.
