FODM3062

Triac, SCR Output Optoisolators Overview

The FODM3062 is a Triac and SCR output optocoupler featuring an integrated zero-crossing detection circuit. It consists of an infrared emitting diode coupled to a hybrid triac driver capable of driving discrete triacs. The device provides electrical isolation with a rated isolation voltage of 5250 Vrms. It operates within a temperature range of -40°C to +85°C. Key electrical parameters include a maximum forward voltage of 1.3 V, a peak forward current of 60 mA, and a maximum trigger current of 10 mA. The off-state voltage rating is 600 V, and the power dissipation is 250 mW.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix code on the component marking against the official datasheet to confirm pinout and packaging configuration. Confirm that the intended application environment remains within the specified operating temperature limits. Ensure input current does not exceed the absolute maximum ratings to prevent LED degradation. Check for any recent process change notifications or obsolescence notices from the manufacturer before finalizing procurement plans.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to minimize inrush currents and noise in AC loads. Compare the 600 V off-state voltage rating against the peak line voltage plus transients in the target application. Evaluate the 10 mA trigger current requirement against the available drive signal strength from the microcontroller or logic interface. Consider the PDIP-6 package constraints for thermal management and board space availability.

Triac, SCR Output Optoisolators Part Context

The FODM3062 belongs to the MOC3 series of optocouplers from onsemi. It is functionally similar to other zero-crossing triac drivers but offers specific integration levels suitable for industrial and consumer AC control. The device represents a transition point in onsemi's portfolio following the Fairchild Semiconductor acquisition, where part numbering conventions may have shifted from underscores to hyphens in some documentation contexts.
