4N27S1(TA)

Overview

The Everlight 4N27S1(TA) is a single-channel transistor output optocoupler housed in a surface-mount 6-SMD package. It provides electrical isolation with a rated insulation voltage of 5000 Vrms. The device features an NPN phototransistor output and supports a maximum forward current of 60 mA with a typical forward voltage of 1.5 V. Key electrical parameters include a collector-emitter voltage of 80 V, a saturation voltage of 500 mV, and a power dissipation rating of 200 mW. The unit operates within a temperature range of -55°C to +110°C.

Feature Summary

Provides high-voltage electrical isolation between input and output circuits
Integrates an infrared emitting diode with an NPN phototransistor detector
Designed for surface-mount assembly using standard soldering methods

Applications

Signal isolation in industrial control systems
Interface circuits for microprocessors and logic devices
Switching applications requiring galvanic isolation

Procurement Notes

Verify the specific lifecycle status before procurement, as this component may be classified as obsolete or end-of-life by the manufacturer. Confirm that the surface-mount package dimensions match the target PCB footprint. Ensure compliance with RoHS directives if required for the final assembly. Cross-reference datasheet revisions to confirm pinout consistency with existing designs.

Selection Notes

Select this component when a surface-mount form factor is required for transistor-output optocouplers. Consider the 5000 Vrms isolation rating for safety requirements. Evaluate the 3 us switching speed against system timing constraints. Verify that the operating temperature range meets environmental specifications. Compare CTR specifications if signal transfer efficiency is critical.

Part Context

This part belongs to the 4N27 family of optocouplers, which are widely used for general-purpose isolation. The 'S1' suffix typically denotes a specific surface-mount variant compared to through-hole DIP versions. The manufacturer offers related variants with different packaging or lead configurations.
