TLP161G(TPR,U,C,F)

Triac, SCR Output Optoisolators Overview

The TLP161G(TPR,U,C,F) is a triac-output optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates an aluminum gallium arsenide infrared emitting diode with a photo-triac detector, providing electrical isolation for AC load control applications. The device features a built-in zero-crossing detection circuit to minimize switching noise and inrush current. It is housed in a compact 6-MFSOP package designed for surface mount assembly. The component offers an insulation voltage of 2500Vrms and supports one channel of operation.

Triac, SCR Output Optoisolators Feature Summary

• Integrates an AlGaAs infrared LED with a photo-triac output for efficient optical coupling
• Includes an internal zero-crossing detection circuit to reduce electromagnetic interference during switching
• Designed for surface mount technology using a mini flat SOP package format

Triac, SCR Output Optoisolators Applications

• AC load control circuits in industrial automation systems
• Solid-state relay interfaces requiring galvanic isolation
• Consumer appliance control boards managing AC power stages

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix (TPR, U, C, or F) against the original design specification to ensure correct packaging and tape configuration. Confirm that the obsolete status does not impact long-term supply chain requirements. Request manufacturer documentation to validate pinout compatibility with existing PCB layouts before procurement.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching capability is required to limit transient currents in AC loads. Ensure the operating voltage remains within the specified limits for the photo-triac output. Verify that the 2500Vrms insulation rating meets the safety isolation requirements of the target application environment.

Triac, SCR Output Optoisolators Part Context

This part belongs to the TLP161 series of mini flat couplers from Toshiba. The series provides various package options including MFSOP and DIP configurations. The TLP161G variant specifically denotes the triac output type with integrated zero-crossing functionality, distinguishing it from standard triac outputs without timing control.

Triac, SCR Output Optoisolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements may require redesigning the isolation interface. Evaluate alternative triac optocouplers with similar zero-crossing features and compatible package dimensions.
