FODM1008R4V

Overview

The FODM1008R4V is a single-channel transistor output optocoupler manufactured by onsemi. It features an NPN phototransistor output housed in a compact LSOP-4 surface-mount package. The device provides high isolation with a rated insulation voltage of 5000 Vrms. Key electrical parameters include a collector-emitter saturation voltage of 300 mV maximum, a forward current of 50 mA, and a forward voltage of 1.4 V. The current transfer ratio ranges from 130% to 260%. Switching characteristics are defined by a rise time of 5.7 µs and a fall time of 8.5 µs. It operates within a temperature range of -40°C to +110°C.

Feature Summary

• Provides galvanic isolation between input and output circuits using infrared LED and NPN phototransistor technology.
• Offers high dielectric strength with a 5000 Vrms insulation voltage rating for safety-critical applications.
• Features low collector-emitter saturation voltage to minimize power loss in the output stage.
• Designed for surface-mount assembly in a small form factor LSOP-4 package.

Applications

• Industrial automation control systems
• Process automation signal isolation
• High-power module interface circuits

Procurement Notes

Verify the specific suffix R4V corresponds to the required tape-and-reel packaging configuration, as standard versions may differ in shipping format. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the exact pinout and isolation ratings specified in the datasheet to avoid compatibility issues in existing designs.

Selection Notes

Select this component when high isolation voltage and low saturation voltage are required in a compact surface-mount footprint. The NPN phototransistor output is suitable for interfacing with digital logic or microcontroller inputs. Consider the 5.7 µs rise time for moderate-speed signal transmission requirements. Evaluate thermal management needs based on the 150 mW power dissipation limit at elevated operating temperatures up to 110°C.

Part Context

This device belongs to the FODM1008 series of transistor output optocouplers from onsemi. The series is designed for general-purpose isolation applications requiring reliable performance in industrial environments. The R4V suffix typically denotes specific packaging or reel specifications within the product line, distinguishing it from bulk or cut-tape variants like the base FODM1008 model.

Replacement Considerations

Compatible substitutes include the FODM1008R2V, which shares identical electrical characteristics and pinout but may differ in packaging quantity or reel specifications. Verify that any replacement maintains the same 5000 Vrms isolation rating and NPN phototransistor output type to ensure circuit functionality remains unchanged.
