FODM3053R2

Triac, SCR Output Optoisolators Overview

The FODM3053R2 is a Triac output optocoupler from onsemi, designed for random phase triggering applications. It features a 600V peak blocking voltage and provides 3750Vrms isolation voltage between input and output channels. The device operates with a maximum DC forward current of 60mA and requires a maximum LED trigger current of 5mA. It supports an RMS on-state current of 70mA and maintains a minimum static dV/dt of 1kV/µs. Operating temperatures range from -40°C to 100°C.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., NF098) against official datasheets to confirm packaging type and reel specifications. Ensure compatibility with required safety certifications such as UL or VDE for the target application environment. Cross-reference pinout configurations to prevent installation errors in surface mount designs.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase triggering is required rather than zero-crossing detection. The 600V blocking voltage suits standard AC line applications. Verify that the 70mA RMS current rating meets load requirements. Consider the 4-SMD footprint constraints during PCB layout planning.

Triac, SCR Output Optoisolators Part Context

This part belongs to the FODM30xx family of Triac output optocouplers. The series offers various voltage ratings including 250V, 400V, and 600V options. These devices are engineered for compact industrial and consumer AC switching solutions requiring galvanic isolation.

Triac, SCR Output Optoisolators Replacement Considerations

Check for direct substitutes within the FODM30xx series with matching voltage ratings. Verify equivalent isolation voltages and current capabilities before substitution. Confirm package compatibility for existing footprints.
