FODM214R2

Overview

The FODM214R2 is a single-channel transistor output optocoupler from onsemi, designed for AC/DC sensing applications. It features an NPN phototransistor output housed in a compact SOP-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 high isolation with a rated insulation voltage of 3750 Vrms. It operates within a wide temperature range of -55°C to +110°C. The current transfer ratio ranges from 20% to 400%, with typical rise and fall times of 3 µs.

Feature Summary

• Provides galvanic isolation between input and output circuits using an LED and phototransistor configuration.
• Supports both AC and DC input signal sensing capabilities for versatile interface applications.
• Offers high voltage isolation capability suitable for protecting low-voltage control circuits from high-voltage noise.

Applications

• AC/DC line sensing circuits
• General-purpose signal isolation
• Microcontroller interface protection

Procurement Notes

Verify the specific suffix R2 confirms the reel packaging format required for automated assembly processes. Ensure the SOP-4 footprint matches the target PCB design constraints. Confirm RoHS compliance status aligns with environmental regulations for the intended market. Cross-reference the manufacturer part number against official datasheets to avoid counterfeit components.

Selection Notes

Select this component when a single-channel isolation solution with moderate speed (3 µs) is required. The SOP-4 package offers space efficiency compared to larger DIP packages. Consider the 3750 Vrms isolation rating for safety requirements. Evaluate the CTR range to ensure sufficient gain for the specific load conditions in the application circuit.

Part Context

This device belongs to the FODM214 series of transistor output optocouplers manufactured by onsemi. The series is characterized by its compact form factor and reliability for industrial and consumer electronics. The R2 suffix typically denotes tape-and-reel packaging, distinguishing it from tube-packaged variants like the FODM214A.

Replacement Considerations

The FODM214 is listed as a related part number in distributor databases, potentially serving as a functional equivalent or predecessor. Verify pinout compatibility and electrical specifications before substitution. Other members of the FODM214 family may offer different packaging options but share similar core characteristics.
