Overview
The FODM2705V is a discontinued AC input-transistor output optocoupler from onsemi, featuring 3750Vrms isolation voltage. It utilizes an NPN phototransistor output with a current transfer ratio ranging from 50% to 300%. Key electrical parameters include a maximum collector-emitter voltage of 40V, a maximum collector current of 80mA, and a forward voltage of 1.3V. The device operates within a temperature range of -40°C to 110°C and exhibits typical rise and fall times of 3μs.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits
- Designed for direct AC input applications without external rectification
- Features fast switching characteristics suitable for signal transmission
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback loops
- Signal interfacing in noisy environments
Procurement Notes
This component is officially listed as discontinued by the manufacturer. Verification of availability should focus on obsolete inventory or authorized distributors holding remaining stock. Ensure that any sourced units are genuine and match the original specifications, as substitutes may require design re-evaluation due to potential parameter variations.
Selection Notes
Engineers replacing this part must consider the discontinuation status. Selection of alternatives requires matching the 3750Vrms isolation rating, NPN transistor output type, and SMD-4 package form factor. Verify that substitute components meet the same AC input compatibility and thermal operating range requirements to maintain system integrity.
Part Context
The FODM2705V belongs to the FODM series of optocouplers from onsemi. This series is characterized by compact surface-mount packages and robust isolation capabilities. The specific model targets applications needing reliable signal transfer across isolated boundaries with minimal propagation delay.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult official replacement guides or contact the manufacturer for qualified alternatives compatible with the FODM series specifications.
