TLP161J(IFT7,U,C,F

Triac, SCR Output Optoisolators Overview

The TLP161J(IFT7,U,C,F) is a Triac and SCR output optocoupler manufactured by Toshiba Semiconductor and Storage. This component is classified as obsolete and is no longer in active production. It features a single-channel configuration designed for AC signal isolation applications. The device integrates an infrared emitting diode with a photo-triac output to provide electrical isolation between control circuits and high-voltage AC loads. As an end-of-life product, it has been discontinued from the manufacturer's portfolio.

Triac, SCR Output Optoisolators Feature Summary

• Single-channel Triac output configuration for AC load control
• Optical isolation between input LED and output triac
• Designed for zero-crossing detection applications

Triac, SCR Output Optoisolators Applications

• AC power switching circuits
• Solid state relay driver interfaces
• Industrial control system isolation

Triac, SCR Output Optoisolators Procurement Notes

This component is officially listed as End of Life (EOL) by Toshiba Semiconductor and Storage. Active manufacturing has ceased, and standard supply channels do not support new orders. Procurement must rely on existing surplus stock or authorized distributors holding legacy inventory. Verification of authenticity and storage conditions is critical when sourcing from secondary markets due to the component's discontinued status.

Triac, SCR Output Optoisolators Selection Notes

Designers should treat this part as unavailable for new implementations. Current projects requiring similar functionality must select alternative active components from Toshiba's current Triac output optocoupler lineup. Evaluate modern substitutes based on matching isolation voltage, forward current requirements, and package dimensions to ensure compatibility with existing board layouts and thermal constraints.

Triac, SCR Output Optoisolators Part Context

The TLP161J belongs to Toshiba's historical range of phototriac optocouplers. It was engineered to provide reliable galvanic isolation for triggering TRIACs and SCRs in AC mains applications. The specific suffixes indicate packaging and tape-and-reel configurations. Its discontinuation reflects the manufacturer's shift toward newer generation devices with enhanced performance specifications and updated compliance certifications.

Triac, SCR Output Optoisolators Replacement Considerations

Direct replacement requires verifying pinout compatibility and electrical parameters against current Toshiba Triac output optocouplers. Substitutes must maintain equivalent isolation ratings and trigger current thresholds. Review datasheets for any differences in zero-crossing behavior or peak off-state voltage to ensure circuit stability.
