TLP168J(TPR,U,C,F)

Triac, SCR Output Optoisolators Overview

The TLP168J is a mini-flat coupler from Toshiba Semiconductor and Storage, designed for surface mount assembly. It integrates an infrared emitting diode with a photo-triac output to provide electrical isolation. The device features a zero-voltage turn-on circuit, ensuring reliable switching of AC loads at the zero-crossing point of the voltage waveform. This component offers high insulation voltage and low power consumption, making it suitable for applications requiring safe and efficient control of AC circuits.

Triac, SCR Output Optoisolators Feature Summary

• Integrates an infrared LED and a photo-triac for optical signal transmission
• Includes a built-in zero-voltage turn-on circuit for precise AC load control
• Utilizes a small-outline package optimized for surface mount technology

Triac, SCR Output Optoisolators Applications

• Solid-state relays for AC load switching

• AC power supply control circuits
• Industrial automation systems requiring isolated switching

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix (TPR, U, C, or F) against your bill of materials, as these denote variations in packaging or tape specifications rather than functional differences. Confirm that the required insulation voltage and current ratings align with your system design before ordering. Ensure compatibility with surface mount reflow soldering profiles specified in the official datasheet.

Triac, SCR Output Optoisolators Selection Notes

Select this component when a compact solution for AC load control with inherent zero-crossing detection is required. It is appropriate for designs prioritizing space efficiency and reduced electromagnetic interference due to soft switching characteristics. Consider the maximum RMS current and peak off-state voltage limits to ensure adequate margin for your specific application environment.

Triac, SCR Output Optoisolators Part Context

This part belongs to Toshiba's mini-flat coupler series, which focuses on providing high-density isolation solutions. The TLP168J specifically addresses the need for reliable triac outputs in small form factors. It complements other optocouplers in the lineup by offering integrated zero-crossing functionality within a standard surface mount footprint.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes may include other Toshiba triac output optocouplers with similar pinouts and electrical characteristics, such as the TLP260J, provided the insulation voltage and package type are compatible. Always verify that any replacement maintains the zero-voltage turn-on feature if critical for your application.
