4N33FSMT&R

Overview

The 4N33FSMT&R is a surface-mount optocoupler manufactured by Isocom Components 2004 LTD. It features a single channel with a Darlington transistor output and a 6-pin DIP package. Key electrical parameters include a maximum forward voltage of 1.65V, a typical rise time of 2µs, and a typical fall time of 11µs. The device supports a maximum input current of 60 mA and offers an isolation voltage of 5.3 kVrms. The current transfer ratio ranges from a minimum of 40% to a maximum of 80%.

Feature Summary

Utilizes a Darlington transistor output configuration for high gain applications
Provides electrical isolation via a 5.3 kVrms dielectric barrier
Designed for surface-mount installation in a compact 6-pin form factor

Applications

Industrial electronics signal isolation
Consumer electronics circuit protection
Microcontroller interface circuits

Procurement Notes

Verify the manufacturer designation as Isocom Components 2004 LTD or Isocom 2004 LTD when sourcing this component. Confirm the specific suffix 'SMT&R' indicates the surface-mount tape-and-reel packaging format. Ensure the part number matches the 4N33FSMT&R identifier exactly to avoid confusion with through-hole variants or other series members within the same family.

Selection Notes

Select this component when high current transfer ratios are required due to its Darlington output structure. It is suitable for applications needing robust galvanic isolation up to 5.3 kVrms. Consider the surface-mount package constraints and the specific pinout of the 6-pin DIP style. Verify that the input current limits and switching speeds align with the target circuit requirements.

Part Context

This part belongs to the CNY17/4N33 family of optocouplers. It shares similar physical dimensions with other devices in the series but differs in internal output configuration. The 4N33 variant specifically employs a Darlington pair, distinguishing it from standard phototransistor outputs found in parts like the CNY17-1SMT&R.
