AC DC Converters, Offline Switchers Procurement Notes

Verify availability status carefully as this component may be subject to discontinuation or limited supply conditions. Confirm the manufacturer designation, noting the transition from Fairchild Semiconductor to onsemi. Ensure the specific suffix RTYDTU matches the required pinout and packaging specifications for your design integration. Cross-reference datasheets for any process changes or compliance updates prior to final procurement decisions.

AC DC Converters, Offline Switchers Selection Notes

Select this component when a 650V rated power switch with 12A capacity is required for AC/DC topologies. The TO-220F package provides suitable thermal dissipation for through-hole implementations. Consider the 0.7Ω on-resistance impact on conduction losses. Verify that the operating temperature range of -25°C to +85°C meets the environmental requirements of the target application.

AC DC Converters, Offline Switchers Part Context

This part belongs to the QRC Power Switch family, which integrates high-voltage MOSFETs with control logic for offline power supplies. Originally released under the Fairchild Semiconductor brand, it is now managed by onsemi following their acquisition. The series is known for combining power switching and control functions to reduce component count in AC/DC converter designs.

AC DC Converters, Offline Switchers Replacement Considerations

Check for direct substitutes within the same QRC Power Switch family with compatible voltage and current ratings. Verify pin compatibility and thermal characteristics if replacing with other TO-220F packaged switches. Consult official obsolescence notices for recommended alternative part numbers.
