4N30SMT&R

Overview

The 4N30SMT&R is a single-channel optoisolator manufactured by Isocom Components 2004 LTD. It features a Darlington transistor output with an integrated base terminal, housed in a 6-SMD gull-wing package. The device provides 5300Vrms isolation voltage and supports a maximum forward current of 80 mA. It operates within a temperature range of -55°C to 100°C.

Feature Summary

• Darlington transistor output configuration with accessible base pin for improved switching control
• High isolation voltage rating of 5300Vrms for robust signal separation
• Surface-mount 6-SMD gull-wing packaging for automated assembly integration

Applications

• General-purpose digital signal isolation
• Microcontroller interface circuits
• Industrial control systems requiring galvanic isolation

Procurement Notes

Verify the manufacturer designation as Isocom Components 2004 LTD against official datasheets. Confirm the 6-SMD gull-wing package type and Darlington output configuration match system requirements. Ensure the 5300Vrms isolation rating meets safety standards for the intended application environment.

Selection Notes

Select this component when a Darlington output with base access is required for high gain applications. The surface-mount form factor suits space-constrained designs. Verify that the 80 mA forward current limit and 5300Vrms isolation are sufficient for the specific circuit topology and noise immunity needs.

Part Context

This part belongs to the standard optocoupler category utilizing infrared LED transmission. It serves as a cost-effective solution for basic isolation tasks where moderate speed and high gain are prioritized over ultra-fast switching characteristics.
