4N32SM

Overview

The 4N32SM is a surface-mount Darlington output optocoupler manufactured by Isocom Components. It features a single channel with an infrared LED input and a high-gain Darlington transistor output. The device provides electrical isolation of 5300 Vrms between input and output circuits. Key electrical parameters include a maximum forward current of 80 mA, a typical current transfer ratio of 500%, and a collector-emitter breakdown voltage of 30 V minimum. It operates within a temperature range of -55°C to 100°C.

Feature Summary

High gain Darlington transistor output configuration for signal amplification
Surface mount plastic package design for automated assembly
High voltage isolation capability between input and output sides

Applications

Industrial control systems requiring galvanic isolation
Signal switching in low-power digital circuits
Microprocessor interface circuits for noise immunity

Procurement Notes

Verify the specific manufacturer designation when sourcing, as Isocom Components may supply devices under different branding or part number variations compared to original equipment manufacturers. Confirm that the surface mount package matches the required footprint and soldering profile for the intended PCB layout. Ensure compliance with relevant safety standards for isolation voltage ratings before integration into certified equipment.

Selection Notes

Select this component when high current transfer ratio is required from a single-channel optoisolator in a surface mount form factor. Consider the 5300 Vrms isolation rating for applications demanding robust electrical separation. Evaluate the thermal performance limits, specifically the 100°C maximum operating temperature, against the expected ambient conditions of the final assembly environment.

Part Context

This device belongs to the 4N32 series of optocouplers, which are characterized by their Darlington output structure. The 'SM' suffix typically denotes a surface mount variant, distinguishing it from through-hole DIP packages. Isocom Components specializes in infrared optoelectronic devices, offering alternatives to standard industry parts with similar pinouts and functional characteristics.
