Overview
The FODM214AV is a single-channel transistor output optocoupler manufactured by onsemi, designed for AC/DC sensing input applications. It features an NPN phototransistor output housed in an MFP-4 surface-mount package. Key electrical parameters include a maximum collector-emitter voltage of 80 V and a continuous collector current of 50 mA. The device provides an insulation voltage of 3750 Vrms. The current transfer ratio ranges from a minimum of 20% to a maximum of 400%. The forward voltage is specified at 1.2 V with a maximum forward current of 50 mA. Switching characteristics include a rise time of 3 µs and a fall time of 3 µs.
Feature Summary
- Provides galvanic isolation between input and output circuits via optical transmission.
- Designed specifically for AC and DC sensing input applications.
- Utilizes an NPN phototransistor output stage for signal switching.
Applications
- AC/DC sensing input circuits
- General purpose signal isolation
- Single channel data transmission
Procurement Notes
Verify the specific suffix AV against the manufacturer's official datasheet to confirm the MFP-4 package configuration and RoHS compliance status. Ensure the ordering part number matches the required tape and reel or tube packaging format as defined in the latest procurement documentation. Cross-reference the component marking with the official silkscreen guide to prevent counterfeit substitution during assembly.
Selection Notes
Select this component when a compact surface-mount solution is required for low-speed digital isolation. The MFP-4 package offers space efficiency compared to standard DIP options. Consider the 3750 Vrms isolation rating for safety requirements. Verify that the 20% to 400% CTR range meets the drive requirements of the downstream logic circuitry under all operating temperature conditions.
Part Context
This component belongs to the FODM214 series of transistor output optocouplers. It shares functional similarities with other members like the FODM214R2 but differs in packaging and specific electrical tolerances. The series is characterized by its suitability for general-purpose isolation tasks where moderate speed and high isolation voltage are prioritized over high-speed data rates.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult the manufacturer's official replacement guide or cross-reference tools for verified alternatives that match the pinout, isolation voltage, and package dimensions.
