Overview
The FOD2742BR2V is a transistor output optocoupler manufactured by onsemi, housed in an 8-SOIC package. It provides electrical isolation with a voltage rating of 2500 Vrms and features a single channel configuration. The device supports a maximum forward current of 20 mA and exhibits a typical forward voltage of 1.5 V. Its collector-emitter saturation voltage is specified at a maximum of 400 mV, while the collector-emitter voltage withstands up to 70 V. The unit operates within a temperature range of -25°C to 85°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Integrates a phototransistor output for signal transmission
- Designed for surface-mount assembly in compact layouts
Applications
- Industrial control systems requiring circuit isolation
- Power supply feedback loops
- Signal transmission across isolated grounds
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm that the marking matches '2742B' as documented in official specifications. Ensure compliance with RoHS3 standards and check for any specific handling requirements related to moisture sensitivity level 1. Validate packaging integrity upon receipt to prevent damage to the SOIC-8 leads.
Selection Notes
Select this component when a robust transistor output isolator is required for moderate-speed applications. Consider the 2500 Vrms isolation barrier for safety-critical designs. Evaluate the thermal operating range against environmental conditions. Compare performance metrics such as current transfer ratio and propagation delays with alternative models if higher speed or different output types are needed.
Part Context
This part belongs to the FOD2742 family of optocouplers from onsemi. It shares functional similarities with variants like the FOD2742BV but differs in packaging and reel specifications. The BR2V suffix indicates a specific tape-and-reel configuration suitable for automated surface-mount placement processes.
Replacement Considerations
Direct substitutes include other FOD2742 series variants such as FOD2742BV, provided pinout and isolation ratings remain compatible. Verify that replacement parts meet the same 2500 Vrms isolation requirement and fit the 8-SOIC footprint.
