Overview
The FODM2705R2V is a single-channel transistor output optocoupler manufactured by onsemi, designed for surface-mount applications. It features an NPN phototransistor output and supports AC input signals. Key electrical parameters include a maximum collector-emitter voltage of 40 V, a maximum collector current of 80 mA, and a forward voltage of 1.4 V at 50 mA forward current. The device provides an insulation voltage of 3750 Vrms and operates within a temperature range of -40°C to +110°C. Power dissipation is rated at 150 mW, with a typical current transfer ratio of 300%.
Feature Summary
- Supports AC input signal detection capabilities
- Provides high isolation voltage for safety compliance
- Utilizes Mini-Flat (SMD-4) package for compact mounting
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal interfacing between low-voltage logic and higher voltage circuits
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging options such as cut tape or reel quantities. Ensure the part number suffix matches the required lead time and manufacturing date codes. Cross-reference datasheet specifications against application requirements before finalizing procurement orders.
Selection Notes
Select this component when AC input detection is required in a surface-mount design. Compare current transfer ratio and saturation voltage against load requirements. Ensure the operating temperature range meets environmental conditions. Verify that the 40 V collector-emitter voltage rating exceeds the maximum circuit voltage.
Part Context
This device belongs to the FODM series of optocouplers from onsemi. It is functionally similar to the FODM2705R2 but utilizes a surface-mount Mini-Flat package instead of through-hole configuration. The series is designed for general-purpose isolation applications where compact size and reliable performance are prioritized.
Replacement Considerations
FODM2705R2 serves as a pin-compatible alternative with identical electrical characteristics but differs in package type. Verify footprint compatibility and thermal management requirements when substituting between SMD and through-hole variants.
