4N33S(TA)

Overview

The 4N33S(TA) is a single-channel optoisolator manufactured by Everlight Electronics Co Ltd. It features an infrared emitting diode coupled to a Darlington phototransistor output with a base terminal for improved switching performance. The device provides high isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to +110°C. It is available in a 6-SMD, Gull Wing surface mount package.

Feature Summary

Integrates an infrared LED emitter with a Darlington phototransistor receiver for enhanced current transfer ratio
Includes a dedicated base terminal on the phototransistor to facilitate faster turn-off times and reduce storage delay
Provides robust electrical isolation between input and output circuits rated at 5000 Vrms

Applications

Signal isolation in industrial control systems
Interface circuits for microprocessors and logic devices
Switching power supply feedback loops

Procurement Notes

Verify the specific suffix TA indicates the tape and reel packaging configuration when ordering. Confirm the manufacturer part number matches Everlight Electronics Co Ltd specifications. Ensure the 6-SMD gull wing footprint aligns with the target PCB design. Check for RoHS compliance status if required by project regulations. Validate lead times as availability may vary by distributor.

Selection Notes

Select this component when a higher current transfer ratio than standard NPN outputs is required. The integrated base allows for external biasing to optimize switching speed. Consider the surface mount form factor for automated assembly processes. Verify that the 5000 Vrms isolation rating meets the safety requirements of the application environment.

Part Context

This device belongs to the 4N33 series of optocouplers from Everlight. It serves as a surface mount alternative to through-hole variants like the 4N33M. The series is widely used for general-purpose signal isolation where moderate speed and high gain are necessary.
