TLP266J(V4T7TR,E

Triac, SCR Output Optoisolators Overview

The TLP266J(V4T7TR,E) is a phototriac output optocoupler manufactured by Toshiba Semiconductor and Storage. It features an integrated zero-crossing detection circuit for precise AC load switching. The device utilizes a GaAs infrared LED coupled to a photo-triac, housed in a compact SO-6-4 surface-mount package. Key electrical specifications include a maximum forward current of 20 mA, an isolation voltage of 3750 Vrms, and a peak off-state voltage (VDRM) of 600 V. The unit supports a maximum trigger current of 10 mA and operates within a temperature range of -25°C to +85°C.

Triac, SCR Output Optoisolators Feature Summary

• Integrated zero-crossing detection circuit ensures low-noise switching at AC voltage zero points.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix (V4T7TR,E) against official Toshiba documentation to confirm tape-and-reel packaging and exact pinout configuration. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Cross-reference datasheet revisions to confirm parameter consistency before finalizing procurement orders.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing functionality is required to minimize electromagnetic interference during AC switching. Compare trigger current requirements against available drive capabilities. Consider thermal management needs given the 200 mW power dissipation limit in the specified package. Validate insulation voltage ratings against system safety standards.

Triac, SCR Output Optoisolators Part Context

This part belongs to the TLP266J series of triac-output photocouplers designed for general-purpose AC load control. It differs from non-zero-crossing variants like the TLP265J by incorporating internal timing logic for synchronized switching. The series is engineered for reliability in industrial environments requiring robust electrical isolation.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes may include other Toshiba zero-crossing triac optocouplers with identical pinouts and electrical ratings. Verify package dimensions and isolation voltage specifications when considering cross-manufacturer alternatives.
