4N32S(TB)-V

Overview

The 4N32S(TB)-V is a single-channel optoisolator manufactured by Everlight Electronics Co Ltd. It features a Darlington transistor output with a base terminal, housed in a surface-mount 6-SMD package. The device provides an isolation voltage of 5000 Vrms and operates within a temperature range of -55°C to 100°C. Key electrical parameters include a maximum collector-emitter voltage of 55V, a typical forward voltage of 1.2V at a maximum forward current of 60mA, and a minimum current transfer ratio of 100% at 1mA input. Switching characteristics specify a turn-on time of 25µs and a turn-off time of 18µs.

Feature Summary

Integrates a high-gain Darlington phototransistor output with a dedicated base pin for improved switching speed control.

Applications

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

Procurement Notes

Verify the specific suffix (TB) against the manufacturer's latest datasheet to confirm pinout orientation and tape-and-reel specifications. Ensure compliance with RoHS directives as indicated in official documentation. Cross-reference the part number with authorized distributors to confirm current availability status and lifecycle stage before finalizing procurement plans.

Selection Notes

Select this component when high gain is required due to the Darlington configuration, while noting that switching speeds are slower than standard phototransistors. The surface-mount package facilitates automated assembly. Verify that the 55V output voltage rating meets the circuit requirements and that the thermal management supports the specified operating temperature range.

Part Context

This component belongs to the 4N32 series of optocouplers from Everlight Electronics. It is designed for general-purpose isolation applications requiring robust signal transmission across isolated barriers. The series typically includes variants with different packaging options, such as DIP and SMD configurations, catering to diverse manufacturing needs.

Replacement Considerations

Compatible substitutes include the 4N32S(TA)-V and other generic 4N32-series equivalents. Verify pin compatibility and electrical ratings before substitution.

FAQ

What is the function of the base pin on the output transistor?

The base pin allows for external connection to improve the turn-off time of the Darlington transistor, enhancing switching performance compared to configurations without a base terminal.
