Overview
The FODM2705R1V is a transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output coupled to an infrared LED. The device provides electrical isolation with a rated insulation voltage of 3750 Vrms. Key electrical parameters include a collector-emitter saturation voltage of 300 mV, a maximum collector current of 80 mA, and a forward voltage of 1.3 V. The unit operates within a temperature range of -40°C to +85°C and is supplied in a 4-SMD Gull Wing package.
Feature Summary
- Integrates an infrared emitting diode with an NPN phototransistor for signal transmission
- Provides high-voltage electrical isolation between input and output circuits
- Designed for surface-mount installation in compact applications
Applications
- General-purpose signal isolation in industrial control systems
- Interface circuits for microcontrollers and logic devices
- Power supply feedback loops requiring galvanic isolation
Procurement Notes
Verify component status as the FODM2705R1V is listed as obsolete and no longer manufactured by onsemi. Confirm availability through authorized distributors or secondary markets if sourcing is required. Ensure that any substitute components meet the original specifications for isolation voltage, pinout compatibility, and thermal performance before integration into designs.
Selection Notes
Select this component when a standard transistor output optocoupler with 3750 Vrms isolation is required. Consider the 80 mA collector current limit and 300 mV saturation voltage for load driving capabilities. Evaluate the 4-SMD package dimensions against board space constraints. Verify that the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the target application.
Part Context
The FODM2705R1V belongs to the FODM2705 family of transistor output optocouplers from onsemi. This series utilizes a gallium arsenide infrared LED coupled to an NPN silicon phototransistor. The family is designed for general-purpose isolation applications, offering reliable performance in compact surface-mount packages suitable for automated assembly processes.
Replacement Considerations
The FODM2705R2 is identified as a similar available substitute part number. Verify pinout compatibility and electrical parameter equivalence before substitution.
