FODM217DR2V

Overview

The FODM217DR2V 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. The device provides robust electrical isolation with an insulation voltage of 3750 Vrms. Key performance metrics include a minimum current transfer ratio of 300% and a maximum of 600%, ensuring reliable signal transmission. It supports a forward current of 50 mA with a forward voltage of 1.4 V. The phototransistor can withstand a maximum collector-emitter voltage of 80 V and a collector current of 50 mA. Switching characteristics are defined by rise and fall times of 3 µs each, making it suitable for general-purpose digital isolation tasks.

Procurement Notes

Verify the specific suffix R2V to confirm tape-and-reel packaging compatibility with automated assembly equipment. Ensure the SOP-4 footprint matches the target PCB layout dimensions. Cross-reference the manufacturer datasheet for absolute maximum ratings regarding thermal dissipation and reverse voltage limits before finalizing component selection for production environments.

Selection Notes

Select this component when a single channel with high current transfer ratio is required for isolated sensing. The SOP-4 package offers a balance between pin count and board space efficiency. Consider the 3 µs switching speed against system timing requirements. Verify that the 80 V collector-emitter voltage rating exceeds the load voltage expectations in the application circuit to ensure long-term reliability under varying operating conditions.

Part Context

This part belongs to onsemi's family of transistor output optocouplers. It shares functional similarities with other single-channel devices but is distinguished by its specific insulation voltage and current transfer ratio specifications. The SOP-4 form factor aligns with industry-standard small-outline packages used in consumer and industrial electronics for cost-effective isolation solutions.
