Overview
The FODM124R2 is a single-channel transistor output optocoupler manufactured by onsemi. It integrates a gallium arsenide infrared emitting diode with a phototransistor to provide electrical isolation between input and output circuits. The device features VDE certification for safety compliance. Key electrical parameters include an isolation voltage of 3750Vrms, a collector-emitter voltage of 80V, and a minimum current transfer ratio of 100% at 1mA forward current. It is housed in a 4-pin Mini-Flat surface-mount package designed for compact PCB layouts.
Feature Summary
- Provides high-voltage electrical isolation via integrated infrared LED and phototransistor
- Features VDE certification for enhanced safety standards compliance
- Utilizes a compact 4-pin Mini-Flat surface-mount package design
Applications
- Industrial control systems requiring signal isolation
- Consumer electronics power supply feedback loops
- General-purpose digital signal transmission across isolated boundaries
Procurement Notes
Verify the specific ordering suffix matches the required tape and reel configuration for automated assembly processes. Confirm that the component status remains active within the manufacturer's portfolio before finalizing procurement plans. Ensure all handling procedures adhere to electrostatic discharge precautions during storage and installation phases.
Selection Notes
Select this component when a low-profile surface-mount solution is required for galvanic isolation. The 80V collector-emitter rating suits standard logic-level switching applications. Verify that the 3750Vrms isolation capability meets the specific safety requirements of the target equipment design and regulatory environment.
Part Context
This part belongs to onsemi's family of transistor output optocouplers designed for general-purpose isolation tasks. The Mini-Flat package variant offers space-saving advantages compared to traditional through-hole DIP packages while maintaining comparable electrical performance characteristics for modern surface-mount technology manufacturing lines.
Replacement Considerations
Cross-reference with other onsemi Mini-Flat series devices if pinout compatibility is critical. Verify equivalent isolation voltages and current transfer ratios when evaluating alternative suppliers or different package variants within the same product family.
