TLP669L(S,C,F)

Triac, SCR Output Optoisolators Overview

The TLP669L(S,C,F) is a triac output optoisolator manufactured by Toshiba Semiconductor and Storage. It features a gallium arsenide infrared LED coupled to a zero-crossing detection triac output. The device provides electrical isolation with an insulation voltage of 5000Vrms. Key electrical parameters include an off-state output terminal voltage of 800 V and a minimum static dV/dt of 200 V/µs. It operates as a single-channel component designed for high noise immunity applications.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix variant (S, C, or F) required for your application, as these denote different packaging or tape-and-reel configurations. Confirm that the obsolete status does not impact long-term supply chain stability for existing designs. Ensure compatibility with the target PCB footprint for the 6-DIP package before finalizing procurement orders.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is critical to minimize inrush current and noise in AC loads. The 800 V off-state voltage rating supports standard mains voltage applications. Consider the 5000Vrms isolation level for safety compliance in high-voltage separation requirements between control and power sections.

Triac, SCR Output Optoisolators Part Context

This part belongs to Toshiba's family of triac output optoisolators designed for AC load switching. It integrates a photodetector and a triac within a single package to provide galvanic isolation. The design emphasizes reliability and noise rejection for use in equipment requiring precise timing and safe operation under varying line conditions.

Triac, SCR Output Optoisolators Replacement Considerations

The TLP669L(S,C,F) is listed as obsolete and no longer manufactured. Engineers must identify equivalent components from other manufacturers that match the 800 V off-state voltage, 5000Vrms isolation, and zero-crossing functionality. Pinout compatibility and package dimensions should be verified for direct replacement.
