FOD2743CS

Overview

The onsemi FOD2743CS is a single-channel optoisolator featuring a phototransistor output and an 8-SMD (鸥翼) package. It provides a 5000Vrms isolation voltage rating for electrical safety. The device operates with a DC input type and supports a collector-emitter saturation voltage of up to 400mV. It handles a maximum output voltage of 70V and a continuous output current of 50mA per channel. The current transfer ratio ranges from 50% to 100% at a forward current of 1mA. The component functions within a temperature range of -40°C to 85°C.

Feature Summary

Provides high-voltage galvanic isolation between input and output circuits
Utilizes a phototransistor output stage for signal transmission
Designed for surface-mount assembly in compact electronic systems

Applications

Industrial control system signal isolation
Power supply feedback loop coupling
Microcontroller interface protection

Procurement Notes

Verify the specific suffix 'CS' to confirm the 8-SMD鸥翼 package configuration, as other suffixes indicate different physical footprints. Confirm end-of-life status with the manufacturer or authorized distributors before finalizing design-in decisions. Ensure compatibility with existing PCB land patterns for the SMD variant. Check for available qualified replacement components if long-term supply stability is required for production runs.

Selection Notes

Select this component when a surface-mount form factor is required for space-constrained designs. The 5000Vrms isolation rating suits applications demanding robust noise immunity in high-voltage environments. Consider the transistor output characteristics for logic-level interfacing tasks. Evaluate the operating temperature range against the environmental conditions of the target application site.

Part Context

This part belongs to the FOD2743 family of optocouplers manufactured by onsemi. The family includes variants with DIP packages such as FOD2743BV and FOD2743BSD. The CS suffix specifically denotes the surface-mount version. These devices are designed for general-purpose isolation applications requiring reliable performance across industrial temperature ranges.
