PC3SD21YTZBF

Triac, SCR Output Optoisolators Overview

The PC3SD21YTZBF is a single-channel optoisolator featuring a Triac output, manufactured by SHARP/Socle Technology. It provides an isolation voltage of 5000Vrms and includes an integrated zero-crossing detection circuit for precise switching control. The device operates with a typical forward voltage of 1.2V and has a maximum activation time of 50µs. It is housed in a compact 6-DIP package, designed for reliable signal transmission across isolated boundaries while minimizing electromagnetic interference through synchronized turn-on at the AC voltage zero point.

Triac, SCR Output Optoisolators Procurement Notes

Verify the manufacturer designation as SHARP/Socle Technology or Sharp Microelectronics to ensure component authenticity. Confirm the package type is 6-DIP and check for relevant safety certifications such as CSA, UR, or VDE depending on regional regulatory requirements. Ensure the specific suffix YTZBF matches the required zero-crossing functionality and packaging format before finalizing procurement orders.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to minimize inrush current and electromagnetic interference in AC circuits. The 5000Vrms isolation rating makes it suitable for high-voltage separation needs. Consider the 50µs activation time for timing-sensitive applications. The 6-DIP package offers standard mounting compatibility for through-hole assembly processes in industrial equipment designs.

Triac, SCR Output Optoisolators Part Context

This part belongs to the family of Triac and SCR output optoisolators from SHARP/Socle Technology. These devices are engineered for applications requiring galvanic isolation between control logic and high-power AC loads. The series emphasizes safety compliance and noise reduction through integrated zero-crossing technology, distinguishing them from standard random-phase optotriacs used in less sensitive switching environments.

Triac, SCR Output Optoisolators Replacement Considerations

Check datasheets for compatible alternatives within the same manufacturer's portfolio that maintain identical pinout configurations and zero-crossing features. Verify that substitute components meet the same 5000Vrms isolation and 6-DIP package requirements to ensure mechanical and electrical interchangeability without redesigning the PCB layout.
