FOD4208TV

Triac, SCR Output Optoisolators Overview

The FOD4208TV is a triac and SCR output optocoupler manufactured by onsemi. It consists of an infrared emitting diode coupled to a hybrid random phase triac capable of driving discrete triacs. The device features snubberless operation, eliminating the need for external RC snubber networks in AC power control applications. Key electrical parameters include an isolation voltage of 5000Vrms, an off-state output voltage (VDRM) of 800V, and a maximum continuous output current rating. The component is housed in a 6-DIP package and complies with RoHS standards.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific ordering suffix 'TV' corresponds to the required tape and reel packaging configuration when sourcing components. Confirm that the selected variant meets all necessary regulatory compliance requirements for the target market. Ensure that the procurement channel provides valid manufacturer traceability documentation to guarantee component authenticity and quality assurance prior to integration into production lines.

Triac, SCR Output Optoisolators Selection Notes

Select this component for designs requiring snubberless operation to reduce bill of materials complexity. Verify that the 800V off-state voltage rating exceeds the peak line voltage of the application. Ensure the input forward current requirements align with the driving logic levels. Check thermal dissipation limits against the expected operating ambient temperature conditions to maintain reliable performance over the product lifecycle.

Triac, SCR Output Optoisolators Part Context

The FOD4208TV belongs to the FOD420 family, which includes devices like the FOD420, FOD4216, and FOD4218.
