FODM3023R4-NF098

Triac, SCR Output Optoisolators Overview

The FODM3023R4-NF098 is a single-channel triac output optocoupler manufactured by onsemi. It features a gallium arsenide infrared LED coupled to a phototriac, providing galvanic isolation with an insulation voltage of 3750 Vrms. The device operates without a zero-crossing circuit, classifying it as a random phase triac driver. Key electrical parameters include a maximum continuous output current of 70 mA and a peak repetitive off-state voltage (VDRM) of 600 V. The component supports a forward current of up to 60 mA and dissipates 300 mW of power. It functions within a temperature range of -40°C to +100°C.

Triac, SCR Output Optoisolators Feature Summary

• Provides high-voltage galvanic isolation between control circuits and power loads via optical coupling.
• Functions as a random phase triac driver, enabling triggering at any point in the AC cycle.
• Integrates a sensitive gate phototriac for efficient switching of AC power devices.
• Designed for surface mount installation in compact MiniFlat packages.

Triac, SCR Output Optoisolators Applications

• Solid state relays requiring random phase triggering
• AC motor speed control systems

Triac, SCR Output Optoisolators Procurement Notes

Verify that the specific suffix NF098 corresponds to the required tape and reel packaging configuration. Confirm that the 600 V blocking voltage rating aligns with the peak line voltages present in the target application circuit. Ensure thermal management strategies account for the specified 300 mW power dissipation limit during operation.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triggering is necessary rather than zero-crossing switching. The 600 V rating suits standard low-voltage AC applications. Consider the MiniFlat package constraints for PCB layout. Verify compatibility with the driving logic levels against the LED forward voltage specifications.
