Overview
The FODM2701BR2 is a single-channel transistor output optoisolator manufactured by onsemi. It features a gallium arsenide infrared LED coupled to an NPN phototransistor in a compact 4-SMD surface-mount package. The device provides high isolation voltage of 3750Vrms between input and output circuits. Key electrical characteristics include a collector-emitter breakdown voltage (VCEO) of 80V, a maximum collector current of 50mA, and a typical rise/fall time of 5 microseconds. The unit operates within a temperature range of -40°C to 110°C.
Feature Summary
- High isolation voltage capability for safe circuit separation
- Compact surface-mount design for space-constrained applications
- Fast switching speed suitable for digital signal transmission
Applications
- Industrial control systems requiring galvanic isolation
- Communication equipment signal interfacing
- Power supply feedback loops
Procurement Notes
Verify the specific suffix 'R2' indicates tape and reel packaging configuration. Confirm the component status as obsolete before finalizing designs. Ensure compatibility with existing footprint requirements for 4-SMD packages. Check for alternative sourcing channels due to potential discontinuation. Validate thermal management needs for the specified operating temperature range.
Selection Notes
Select this component when high isolation voltage and small form factor are critical. Consider the transistor output type for logic-level interfacing. Evaluate the 5-microsecond switching speed against system timing requirements. Assess the 80V collector-emitter voltage rating for load compatibility. Verify the surface-mount mounting style matches the PCB assembly process.
Part Context
This part belongs to onsemi's family of transistor output optocouplers designed for general-purpose isolation. The FODM2701 series offers reliable performance in noisy environments. The BR2 suffix typically denotes specific packaging or testing variations within the product line. These devices are commonly used where electrical safety standards require reinforced insulation barriers.
Replacement Considerations
Public sources indicate the FODM2701BR2 is classified as obsolete. No direct public substitute part numbers are confirmed in the provided data. Designers should consult official obsolescence notices for recommended alternatives.
