FODM1009R2

Overview

The FODM1009R2 is a single-channel transistor output optocoupler manufactured by onsemi, designed for 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 a rated insulation voltage of 5000 Vrms. Key electrical parameters include a minimum current transfer ratio of 200% and a maximum of 400%, ensuring reliable signal transmission. The input forward current is rated at 50 mA with a forward voltage of 1.4 V. The output can withstand a maximum collector-emitter voltage of 70 V and a maximum collector current of 50 mA. Timing characteristics specify a typical rise time of 5.7 µs and a fall time of 8.5 µs. The component operates within a temperature range of -40°C to +110°C and has a power dissipation rating of 150 mW.

Feature Summary

• Provides high-voltage isolation between input and output circuits using optical coupling technology.

Applications

• DC sensing input circuits
• General purpose signal isolation

Procurement Notes

Verify the specific ordering suffix R2 corresponds to the required tape and reel packaging configuration before procurement. Confirm that the SOP-4 package dimensions align with the target PCB footprint. Ensure the thermal management design supports the specified power dissipation limits under maximum operating conditions. Cross-reference the manufacturer datasheet for any recent updates to mechanical drawings or reliability data.

Selection Notes

Select this component when a single-channel isolation barrier is required for low-speed DC signals. The NPN phototransistor output is suitable for interfacing with digital logic inputs. Consider the 5000 Vrms isolation rating for safety compliance in mains-connected systems. Evaluate the 200% to 400% current transfer ratio range to ensure adequate noise margin for the application.

Part Context

This part belongs to the FODM1009 series of transistor output optocouplers from onsemi. The series is characterized by its small form factor and suitability for space-constrained designs. The R2 suffix typically denotes a specific packaging variant, such as tape and reel, intended for automated assembly processes. It serves as a standard solution for basic galvanic isolation needs in industrial and consumer electronics.

Replacement Considerations

Direct substitutes may include other single-channel NPN output optocouplers with comparable isolation voltages and CTR ranges. Verify pinout compatibility and package dimensions to ensure drop-in replacement feasibility without PCB redesign.
